Nicolas CRAMP\u00c9<\/span>Charg\u00e9 de recherche, CNRS<\/span><\/div><\/div>
01\/09\/2025 – 31\/12\/2025
\nAfter completing his higher education at the *\u00c9cole Sup\u00e9rieure de Physique et de Chimie Industrielles* (ESPCI Paris), Nicolas Cramp\u00e9<\/a> pursued a doctoral thesis at the *Laboratoire d’Annecy de Physique Th\u00e9orique (LAPTh)* (LAPTh) at the University of Savoie. He joined CNRS in 2009 and successively held positions at the University of Montpellier and then at the University of Tours from 2018 onward.<\/p>\n

A specialist in exactly solvable systems and representation theory, Nicolas Cramp\u00e9 employs algebraic tools to explore the underlying symmetries of various physical problems. His research focuses on calculating entanglement entropies in quantum mechanics, evaluating mean values in non-equilibrium statistical models, and spectral analysis of Hamiltonians. More recently, he has also shown interest in certain special functions and their role in studying algebra representations, understanding association schemes, and analyzing quantum integrable models.<\/div><\/div><\/div>

Lucile DEVIN<\/span>Ma\u00eetre de conf\u00e9rences, Universit\u00e9 du Littoral C\u00f4te d'Opale<\/span><\/div><\/div>
01\/09\/2025 – 31\/08\/2026
\nLucile Devin<\/a> is an Associate Professor at the Universit\u00e9 du Littoral C\u00f4te d\u2019Opale (Calais). She specializes in analytic number theory and defended her PhD in 2017 under the supervision of Florent Jouve at the Laboratoire de Math\u00e9matiques d\u2019Orsay. She then pursued several postdoctoral positions, which initiated many collaborations: with Daniel Fiorilli at the University of Ottawa, Chantal David at the Centre de Recherches Math\u00e9matiques in Montr\u00e9al, and Anders S\u00f6dregren at Chalmers University, Gothenburg.<\/p>\n

Her research focuses on two specific areas within analytic number theory. Following Chebyshev\u2019s observation suggesting a bias in the distribution of prime numbers among congruence classes, Lucile Devin has studied axiomatizations and generalizations of such biases. Some hypotheses proposed to explain this phenomenon require a deeper understanding of the zeros of associated L-functions. Her second line of research addresses precisely this point: proving certain instances of the Katz\u2013Sarnak and Sarnak\u2013Shin\u2013Templier universality conjectures concerning the vertical distribution of zeros in families of L-functions.<\/div><\/div><\/div>

Richard GRIFFON<\/span>Ma\u00eetre de conf\u00e9rences, Universit\u00e9 Clermont-Auvergne<\/span><\/div><\/div>
01\/02\/2026 \u2013 31\/08\/2026
\nRichard Griffon has been a ma\u00eetre de conf\u00e9rences (associate professor) at Universit\u00e9 Clermont Auvergne since January 2021. His research lies at the intersection of number theory and Diophantine geometry. His work primarily focuses on the arithmetic of elliptic curves and abelian varieties over function fields, the asymptotic study of special values of their L-functions\u2014following the spirit of the Brauer\u2013Siegel theorem and its generalisations\u2014as well as isogenies between abelian varieties and their interactions with various notions of height. He defended his PhD thesis in July 2016 at Universit\u00e9 Paris Diderot, under the supervision of Marc Hindry, on analogues of the Brauer\u2013Siegel theorem for families of elliptic curves defined over function fields. After his PhD, he was a postdoctoral researcher at Universiteit Leiden and then at Universit\u00e4t Basel. He is a member of the GAEC (ANR) and PadLEfAn (ANR) projects, as well as the international network IRN GandA (CNRS).<\/p>\n

In his work, he established an unconditional analog of the Brauer\u2013Siegel theorem for several families of (super)elliptic curves, including Legendre curves, Hessian curves, and superelliptic curves over function fields, as well as for the family of Fermat surfaces over finite fields. He achieved this by explicating the associated L-functions and analyzing the fine distribution properties of their zeros. In collaboration with Le Fourn and Pazuki, he obtained results on the differential height variation in isogeny classes of abelian varieties over function fields and an optimal isogeny theorem for elliptic curves in this context.<\/div><\/div><\/div>

01\/09\/2025 – 31\/08\/2026
\nClaire Guerrier<\/a> defended her PhD in mathematical modeling for neuroscience in 2011. After a postdoctoral fellowship at UBC, where she worked between the Department of Mathematics and the Brain Research Center, she has been a CNRS research scientist at the *Laboratoire Jean-Alexandre Dieudonn\u00e9* (CNRS & Universit\u00e9 C\u00f4te d’Azur) since 2019. Her expertise focuses on solving multiscale problems, combining stochastic and continuous parts, asymptotic analysis, and mean first-passage time theory. She has led several interdisciplinary projects with experimental laboratories \u2014 on the pre-Botzinger complex with the Paris-Saclay Neuroscience Institute (CNRS & Universit\u00e9 Paris-Saclay), on neuronal integration with the Faculty of Medicine at the University of British Columbia (UBC), and on myelin adaptation with the MBP consortium (McGill University), as well as a recent project on fungal growth with the Laboratoire interdisciplinaire des \u00e9nergies de demain (Universit\u00e9 Paris Cit\u00e9).<\/div><\/div><\/div>
S\u00e9bastien LABB\u00c9<\/span>Charg\u00e9 de recherche, CNRS<\/span><\/div><\/div>
01\/09\/2025 \u2013 14\/07\/2026
\nS\u00e9bastien Labb\u00e9<\/a> has been a CNRS research fellow at the Laboratoire Bordelais de Recherche en Informatique at the University of Bordeaux since January 2017, after postdoctorates at the University of Paris-Diderot Paris 7 and the University of Li\u00e8ge (Belgium). S\u00e9bastien Labb\u00e9 obtained his PhD in 2012 in mathematics and computer science at the Universit\u00e9 du Qu\u00e9bec \u00e0 Montr\u00e9al under the supervision of Srecko Brlek. He is currently at the University of Montpellier for the second year of his thesis, carried out under a France-Quebec cotutelle under the co-direction of Val\u00e9rie Berth\u00e9.<\/p>\n

S\u00e9bastien Labb\u00e9 is interested in combinatorics, discrete geometry, symbolic dynamics and number theory. His research explores the interactions between these fields, contributing to a better understanding of dynamical systems and geometric structures. His most recent results concern aperiodic Jeandel-Rao tessellations, which he describes by substitutions and by cutting and projection schemes in dimension 4. He is also interested in numeration systems, continued fractions and their generalizations in higher dimensions, and open problems such as Markoff’s injectivity conjecture. Since 2008, he has been involved in the development of the SageMath open-source mathematical software, which he uses daily in his research. During his stay at the CRM in 2025-2026, he is keen to develop new collaborations with LaCIM colleagues in the field of mathematics.<\/div><\/div><\/div>

Didier LESESVRE<\/span>Ma\u00eetre de conf\u00e9rences, Universit\u00e9 de Lille<\/span><\/div><\/div>
04\/01\/2026 \u2013 03\/07\/2026
\nDidier Lesesvre<\/a> is a lecturer at the University of Lille. His research focuses on number theory and the analytic theory of automorphic forms. He completed his thesis in Paris under the supervision of Farrell Brumley, during which time he benefited from extended research stays at EPFL with Ian Petrow and Philippe Michel, as well as in G\u00f6ttingen with Valentin Blomer. He defended his thesis in 2018 and then worked for three years at Sun Yat-Sen University in China.
\nHis work focuses more specifically on families of automorphic forms, using duality formulas from noncommutative harmonic analysis: trace formulas. While automorphic forms are difficult to study individually, these tools make it possible to obtain arithmetic statistics, i.e., average results for these families. He has worked on making Arthur’s trace formula usable in practice in the context of quaternion algebras, and the relative trace formula in the context of GSp(4). He has thus established Weyl’s laws for certain families of automorphic forms, density theorems controlling the number of exceptional forms, given global and local distribution results, and studied various statistics on the zeros of automorphic L-functions.<\/div><\/div><\/div>
Marc-Hubert NICOLE<\/span>Professeur des universit\u00e9s, Universit\u00e9 de Caen<\/span><\/div><\/div>
01\/09\/2025 – 31\/08\/2026
\nMarc-Hubert Nicole has been a full professor at Universit\u00e9 de Caen since 2021, after completing his habilitation to supervise research (HDR) in May 2020. He supervised the PhD of Francesco Iudica (now a postdoctoral fellow at Beijing University, China) on the p-adic Kudla program for the unitary group U(3), as well as the postdoctoral fellowship of Maria Rosaria Pati (now a tenure-track professor in Genoa, Italy).<\/p>\n

Since 2021, he has been actively involved in the development of the p-adic Kudla program in arithmetic geometry, notably through the organization of events encouraging the participation of young scientists already working either on the classical Kudla program or on p-adic methods: the 30th Arithmetic Meetings in Caen in May 2022, the Cetraro conference on \u201cArithmetic Theta Series and p-adic Modular Forms\u201d in June 2024, and the Luminy conference on \u201cp-adic Aspects of the Kudla Program\u201d in June 2026.<\/p>\n

During a previous stay in Montr\u00e9al in 2020\u20132021 (with the support of the CRM-CNRS IRL), he co-organized at the CRM, together with Henri Darmon (McGill) and many other participants, an in-person seminar during the (pandemic) thematic trimester of fall 2020 on the early stages of the program. In winter 2021, he co-funded the postdoctoral fellowship of Jackson Morrow (now an assistant professor in Texas) at the CRM and, with him and Giovanni Rosso (Concordia), organized a working group on non-Archimedean variants of o-minimal geometry.<\/div><\/div><\/div>

Emmanuel ROYER<\/span>Professeur des universit\u00e9s, Universit\u00e9 Clermont-Auvergne<\/span><\/div><\/div>
01\/09\/2025 – 31\/08\/2026
\nEmmanuel Royer<\/a> is a university professor at the University of Clermont-Auvergne, where he directed the *Laboratoire de math\u00e9matiques Blaise Pascal* from 2014 to 2018. He then became Deputy Scientific Director of the National Institute for Mathematical Sciences and their Interactions at CNRS from 2018 to 2023, responsible for support units (including the CIRM in Marseille, the IHP in Paris, and Mathdoc, which promotes open access publishing), mediation and educational links, gender parity, and communication.<\/p>\n

Since completing his PhD under the supervision of \u00c9tienne Fouvry and Philippe Michel, which he defended in 2001, he has worked in number theory, focusing particularly on modular forms and related functions. Recently, for example, he has studied the distribution of partial sums of Kloosterman sums from an analytical perspective; and, from a more algebraic viewpoint, the formal deformations of quasi-modular and Jacobi forms generalizing Rankin-Cohen brackets.<\/div><\/div><\/div>

During the academic year, the National Center for Scientific Research<\/a>\u00a0hosts the following scientists at the international research laboratory in mathematics it has established in Montreal with the Centre de Recherches Math\u00e9matiques<\/a>.<\/p>\n<\/div>

Pierre BAUMANN<\/span>Charg\u00e9 de recherche, CNRS<\/span><\/div><\/div>
01\/11\/2024 – 30\/06\/2025
\nPierre Baumann<\/a> is a research scientist at CNRS, based at the *institut de recherche math\u00e9matique avanc\u00e9e* in Strasbourg. His research focuses on the representations of Lie groups and algebras, sitting at the intersection of algebra, combinatorics, and geometry. In his mathematical garden, one can find various species of preprojective algebras, varieties of affine Grassmannians, affine root systems, crystal bases of polytopes and paths, cluster structures, and the ever-intriguing perverse sheaves. His stay at the CRM will allow him to continue his long-standing collaborations with colleagues from LACIM (UQAM).<\/p>\n

Pierre Baumann has also been involved in various outreach activities at the local level. He notes that one of his \u201ccurses\u201d is that his most widely read mathematical text is a handout on the history of the discipline for undergraduate students, while (in his opinion) some of his more personal works are equally deserving of attention.<\/div><\/div><\/div>

Nicolas BOUSQUET<\/span>Charg\u00e9 de recherche, CNRS<\/span><\/div><\/div>
01\/09\/2024 – 31\/08\/2025
\nAfter completing a PhD in theoretical computer science in 2013 at LIRMM in Montpellier, [Nicolas Bousquet](https:\/\/perso.liris.cnrs.fr\/nbousquet\/) joined CNRS in 2016 as a research scientist, first at the G-SCOP laboratory in Grenoble and then at the LIRIS laboratory in Lyon since 2020.<\/p>\n

The core of his research focuses on structural graph theory and graph algorithms. However, his research interests extend beyond these areas: game theory, combinatorics, etc. In recent years, he has been particularly interested in reconfiguration problems, which aim to determine the conditions that guarantee the existence of transformations between solutions to a problem. He has also explored distributed algorithms and local certification problems.<\/p>\n

This year, he is hosted at the LACIM (Laboratory of Algebra, Combinatorics, and Mathematical Computing) at UQAM, where he is investigating the connections between combinatorics and reconfiguration.<\/div><\/div><\/div>

Mich\u00e8le COUDERETTE<\/span>Ma\u00eetresse de conf\u00e9rences, Universit\u00e9 Paris-Est Cr\u00e9teil<\/span><\/div><\/div>
01\/09\/2024 – 31\/08\/2025
\nAfter completing a PhD under the supervision of Amade-Escot, Dorier, and Leutenegger, defended in 2018 and entitled \u201cA Comparative Study on the Implementation of a Didactic Engineering for Teaching Subtraction in the First Cycle of Primary Education Across Several Didactic Systems: Case Studies in Switzerland and France\u201d, Mich\u00e8le Couderette<\/a> has been an assistant professor in mathematics didactics at the University of Paris-Est Cr\u00e9teil since 2019. Her research, conducted within the Andr\u00e9 Revuz Didactics Laboratory (LDAR), is closely related to teacher training and focuses on the analysis of teaching practices in ordinary contexts. It aims to account for transpositive phenomena at play during the implementation of teaching situations and to determine the modalities of co-construction of knowledge by students and their teachers.<\/p>\n

Since 2019, her research has specifically focused on the teaching of algorithms in primary and secondary education, particularly the interactions between algorithms and mathematics in programming tasks that involve mathematical knowledge. During her stay at the CRM-CNRS in Montreal, she plans to give her research a comparative dimension: the comparison of didactic systems from countries with different teaching cultures and traditions helps to highlight the generic and specific dimensions of teaching and learning practices, thus providing insight into what determines teachers’ actions from both institutional and personal perspectives.<\/div><\/div><\/div>

01\/01\/2025 – 31\/08\/2025
\nAfter completing his higher education at the *\u00c9cole Sup\u00e9rieure de Physique et de Chimie Industrielles* (ESPCI Paris), Nicolas Cramp\u00e9<\/a> pursued a doctoral thesis at the *Laboratoire d’Annecy de Physique Th\u00e9orique (LAPTh)* (LAPTh) at the University of Savoie. He joined CNRS in 2009 and successively held positions at the University of Montpellier and then at the University of Tours from 2018 onward.<\/p>\n

A specialist in exactly solvable systems and representation theory, Nicolas Cramp\u00e9 employs algebraic tools to explore the underlying symmetries of various physical problems. His research focuses on calculating entanglement entropies in quantum mechanics, evaluating mean values in non-equilibrium statistical models, and spectral analysis of Hamiltonians. More recently, he has also shown interest in certain special functions and their role in studying algebra representations, understanding association schemes, and analyzing quantum integrable models.<\/div><\/div><\/div>

\nSophie Dabo-Niang<\/a> is a professor of applied mathematics at the University of Lille until 2010 and a researcher at INRIA Lille. She holds a PhD in statistics from Sorbonne University (2002). After a first teacher and researcher position at University Paris 2 from 2002 to 2004, she obtained an assistant Professor position at University Lille 3 in 2004. Her research focuses on the representation of time and spatial in random environments through the use of stochastic changes driven by real problems in various areas (i.e biology, economics, epidemiology, physics, environmental and hydrological studies, oncology).<\/p>\n

She has authored over 80 scientific articles and 2 books, and has supervised 16 PhD theses. She led the Quantitative Methods team at the LEM CNRS 9221 (2015-2019) and the EQUIPPE laboratory at Lille 3 (2010-2015). She is currently leading the mathematics team at the Oncolille Institute. She is deeply committed to promoting mathematics and fostering the inclusion of women.

\nSebastien Darses<\/a> is an assistant professor in mathematics at Aix-Marseille University. He has worked in various fields, including high-dimensional probability and statistics. His recent interests lie in analytic number theory, specifically concerning approximation problems and identities related to the Riemann zeta function. S-He is is also the leader of the educational project [HighKholl](https:\/\/sites.google.com\/view\/sebastien-darses\/teaching-project).<\/div><\/div><\/div>

01\/09\/2024 – 31\/08\/2025
\nThierry Daud\u00e9 has been an assistant professor in mathematics since 2010, initially at the University of Cergy-Pontoise, and since 2022 at the University of Franche-Comt\u00e9. His research mainly focuses on the study of geometric inverse problems stemming from general relativity or medical imaging. For example, he is interested in the anisotropic Calder\u00f3n problem, which explores whether it is possible to determine (or even reconstruct) a metric within a compact Riemannian manifold with boundary based on measurements taken solely on the boundary. These measurements are encoded by the Dirichlet-to-Neumann operator. Alongside colleagues F. Nicoleau (Nantes) and N. Kamran (Montreal), he has notably produced counterexamples to uniqueness in the local Calder\u00f3n problem for manifolds with only H\u00f6lder regularity. In the field of general relativity, Thierry Daud\u00e9 is currently interested in determining the geometry of black hole-type spacetimes based on the knowledge of the quasinormal modes (resonances) of these black holes. This work is motivated by the fact that the frequencies of these resonances can now be calculated thanks to the LIGO and VIRGO gravitational wave detectors.<\/div><\/div><\/div>

01\/09\/2024 – 31\/12\/2024
\nDenis Grebenkov<\/a> is a CNRS research director at the Institute of Physics. After defending his thesis in 2004 at \u00c9cole Polytechnique, his research has focused on diffusion phenomena and their applications. The central question of his studies is to understand the link between the geometric structure of a complex system and its transport properties. This theme encompasses various topics across different disciplines. On the mathematical side, it involves the spectral properties of the Laplace operator, the Steklov problem, even non-Hermitian operators, the description of stochastic processes confined by irregularly shaped interfaces, asymptotic analysis, optimization, and inverse spectral problems. On the applied side, it addresses intracellular transport, diffusion-controlled chemical reactions, first-passage statistics, and more. These studies combine theoretical and numerical tools and involve collaborations with experimentalists.<\/p>\n

Denis Grebenkov is the author of 185 publications, and his contributions have been recognized with the thesis prize from \u00c9cole Polytechnique in 2004, the Giulio Cesare Borgia Prize in 2010, the CNRS Bronze Medal in 2012, and the Friedrich Wilhelm Bessel Prize in 2019.

More precisely, his work deals on the one hand with an original construction of ALF hyperk\u00e4hlerian metrics using global analysis techniques, and on the other with structure theorems (uniqueness, asymptotic behavior) of complete, finite-volume Kcsc or even \u201cextremal\u201d metrics on the complementary of a divisor.
\nBeyond complex geometry (with algebraic accents), singular complex Monge-Amp\u00e8re equations are at the heart of most of this work, and remain very present in Auvray’s current investigations, such as the deformation of ALF metrics up to certain critical thresholds, and the analysis of Kcsc\/extreme metrics through the Chen-Cheng approach.<\/p>\n

H.A. has been a member of several ANR projects in recent years, as well as the main organizer of the Orsay Harmonic Analysis seminar in 2027-2019, and the co-organizer of various working groups, workshops and conferences. He is also the recipient of a Simons Chair in spring 2024, on the occasion of the thematic semester Geometric Analysis at the CRM. <\/div><\/div><\/div>

Denis GREBENKOV<\/span>Directeur de recherche, CNRS<\/span><\/div><\/div>
01\/07\/2024 – 31\/08\/2024
\nDenis Grebenkov<\/a> is a CNRS research director at the Institute of Physics. After defending his thesis in 2004 at \u00c9cole Polytechnique, his research has focused on diffusion phenomena and their applications. The central question of his studies is to understand the link between the geometric structure of a complex system and its transport properties. This theme encompasses various topics across different disciplines. On the mathematical side, it involves the spectral properties of the Laplace operator, the Steklov problem, even non-Hermitian operators, the description of stochastic processes confined by irregularly shaped interfaces, asymptotic analysis, optimization, and inverse spectral problems. On the applied side, it addresses intracellular transport, diffusion-controlled chemical reactions, first-passage statistics, and more. These studies combine theoretical and numerical tools and involve collaborations with experimentalists.<\/p>\n

Denis Grebenkov is the author of 185 publications, and his contributions have been recognized with the thesis prize from \u00c9cole Polytechnique in 2004, the Giulio Cesare Borgia Prize in 2010, the CNRS Bronze Medal in 2012, and the Friedrich Wilhelm Bessel Prize in 2019. He is the recipient of a Simons Chair in fall 2024 to conduct research on the Steklov problem in collaboration with Canadian mathematicians.<\/div><\/div><\/div>

01\/09\/2023 – 31\/08\/2024
\nAfter completing a PhD under the supervision of Amade-Escot, Dorier, and Leutenegger, defended in 2018 and entitled \u201cA Comparative Study on the Implementation of a Didactic Engineering for Teaching Subtraction in the First Cycle of Primary Education Across Several Didactic Systems: Case Studies in Switzerland and France,\u201d Mich\u00e8le Couderette has been an associate professor in mathematics didactics at the University of Paris-Est Cr\u00e9teil since 2019. Her research, conducted within the Andr\u00e9 Revuz Didactics Laboratory (LDAR), is closely related to teacher training and focuses on the analysis of teaching practices in ordinary contexts. It aims to account for transpositive phenomena at play during the implementation of teaching situations and to determine the modalities of co-construction of knowledge by students and their teachers.<\/p>\n

Since 2019, her research has specifically focused on the teaching of algorithms in primary and secondary education, particularly the interactions between algorithms and mathematics in programming tasks that involve mathematical knowledge. During her stay at the CRM-CNRS in Montreal, she plans to give her research a comparative dimension: the comparison of didactic systems from countries with different teaching cultures and traditions helps to highlight the generic and specific dimensions of teaching and learning practices, thus providing insight into what determines teachers’ actions from both institutional and personal perspectives.<\/div><\/div><\/div>

Yves D\u2019Angelo <\/span>Professor of Applied Mathematics at Universit\u00e9 C\u00f4te d'Azur <\/span><\/div><\/div>
Yves D’Angelo has been Professor of Applied Mathematics at Universit\u00e9 C\u00f4te d’Azur in Nice since 2016, and a research associate at the Inria center at Universit\u00e9 C\u00f4te d’Azur in Sophia-Antipolis.
\nPreviously Professor at INSA Rouen (from 2005 to 2016), he was also a research associate at the Laboratoire Interdisciplinaire des Energies de Demain at the University of Paris.
\nHis career alternates between academic positions in France (Paris, Poitiers, Rouen, Nice) and abroad (Yale, Milan, Lund),
\nas well as in industry (Dassault, EADS, MBDA).
\nSome of his research activities concern mathematical modeling and asymptotic analysis in the context of turbulent combustion and active interfaces: stochastic integro-differential equations with memory, nonlinear and non-local stochastic evolution equations, network approaches to directed percolation.
\nOther work is more applied, involving direct numerical simulation (DNS) or large-scale simulation (LES), on massively parallel machines and using dedicated algorithms (HPC) of reactive turbulent multispecies fluid flows.<\/p>\n

Some of Yves D’Angelo’s work combines DNS (small-scale) and asymptotic approaches (meso or macro-scale), with a strong software and algorithmic development component. Our experience in modeling and simulation of reactive, turbulent, multiphase, disordered, supersonic and granular flows, active fronts, acoustics, free boundary problems, interface instabilities, etc., also enables us to direct some of our activities towards interactions with other disciplines in physics and biology: nanothermoplasmonics, multiscale modeling of biological networks (network of hyphae in the filamentous fungus Podospora anserina, developing neurons in the brain of Xenopus laevis. )
\nPhysics-based machine learning, linked to his experience of active fronts, is also part of his future research projects. <\/div><\/div><\/div>

She has led several interdisciplinary projects with experimental laboratories \u2014 on the pre-Botzinger complex with the Paris-Saclay Neuroscience Institute (CNRS & Universit\u00e9 Paris-Saclay), on neuronal integration with the Faculty of Medicine at the University of British Columbia (UBC), and on myelin adaptation with the MBP consortium (McGill University), as well as a recent project on fungal growth with the Laboratoire interdisciplinaire des \u00e9nergies de demain (Universit\u00e9 Paris Cit\u00e9).<\/div><\/div><\/div>
Yann Rollin<\/span>Professor at the University of Nantes<\/span><\/div><\/div>
Yann Rollin has been a professor at the University of Nantes since 2008, and is a member of the Jean Leray Laboratory, having previously been a Moore Instructor at MIT, then a University Research Fellow of the Royal Society. His research in differential geometry is mainly concerned with K\u00e4hlerian geometry and the Calabi program, i.e., the search for canonical metrics on complex varieties. Thanks to recollement theorems, he has also obtained results in gauge theory with applications to contact topology (with Tom Mrowka). He also succeeded in recollecting wormholes on asymptotically complex hyperbolic Einstein varieties (with Olivier Biquard). More recently, he has turned his attention to the emerging field of piecewise linear symplectic geometry. He has shown, for example, that any Lagrangian torus of R^4 admits piecewise linear approximations.<\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":6,"featured_media":0,"parent":19202,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"footnotes":""},"class_list":["post-14532","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/pages\/14532","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/comments?post=14532"}],"version-history":[{"count":43,"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/pages\/14532\/revisions"}],"predecessor-version":[{"id":20950,"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/pages\/14532\/revisions\/20950"}],"up":[{"embeddable":true,"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/pages\/19202"}],"wp:attachment":[{"href":"https:\/\/www.crmath.ca\/en\/wp-json\/wp\/v2\/media?parent=14532"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
