Mercator Fellow

Mercator Fellow 3rd Period

The Mercator Fellow of the SFB of the 3rd period is Cécile Gachet. Cécile Gachet is an expert in complex and birational geometry with very broad interests. Among her other recent works, she and her co-authors show that a smooth complex projective surface has at most finitely many mutually non-isomorphic real forms unless it is either rational or a non-minimal surface birational to a K3 or Enriques surface.

She is a Juniorprofessor for algebraic geometry at Ruhr-University Bochum .

Before coming to Bochum, she has obtained her Ph.D. in February 2023 at Université Côte d’Azur under the supervision of Andreas Höring. From May 2023 to September 2024, she worked as a postdoctoral fellow in the group led by Gavril Farkas at Humboldt-Universität zu Berlin.

Mercator Fellow 2nd Period

The Mercator Fellow of the SFB of the 2nd period is Dhruv Ranganathan. His research focuses
on combinatorial algebraic geometry, in particular log geometry and tropical geometry. A special focus of his research is on moduli spaces and enumerative geometry.

Dhruv Ranganathan is a professor at the University of Cambridge and a Fellow and St. John’s College. He holds an ERC Starting Grant. Before, he was a Postdoc at the MIT and a Member of the Institute of Advances Study in Princeton. He completed his Ph. D. in 2016 under the supervision of Sam Payne in Yale. His current webpage can be found here.

Mercator Fellow 1st Period

The Mercator Fellow of the SFB is Olivier Dudas. His research focuses on modular representation theory of finite reductive groups, with a particular interest in the geometric version of Broué’s abelian defect group conjecture.

Olivier Dudas is currently a Chargé de Recherches (Research Fellow) at the CNRS, working at the Université Paris Diderot – Paris 7. Before that he was an EPSRC Postdoc in Oxford, as well as a Junior Research Fellow of Magdalen College, Oxford. He completed his Ph.D. in 2010 under the supervision of Cédric Bonnafé in Besançon. His current webpage can be found here.

Olivier Dudas spends research visits at the main locations of the TRR on a regular basis.
