Coordinator

Fernando Zalamea

Fernando Zalamea is Professor of Mathematics at Universidad Nacional de Colombia. After his Ph.D. in category theory and recursion theory (University of Massachusetts, 1990, under Ernest Manes), Zalamea has been working in alternative logics, Peirce and Lautman studies, and the philosophy of modern (1830-1950) and contemporary mathematics (1950-today). He is the author of thirty books around cultural studies, philosophy, and mathematics. His triad (Filosofía sintética de las matemáticas contemporáneas, 2009; Modelos en haces para el pensamiento matemático, 2021; Crítica matemática, 2024), part of it translated to English and French, has opened new roads for the philosophy of mathematics. His Grothendieck. Una guía a la obra matemática y filosófica (2019) is the first complete guide to Grothendieck’s published work. He has been included as one of 100 Global Minds. The Most Daring Cross-Disciplinary Thinkers in the World (Roads 2015).  

Archive Manager and WebMaster

Mateo Carmona

Mateo Carmona is a Grothendieck scholar and former coordinator of the CSG, he has dedicated several years to studying and disseminating A. Grothendieck’s scientific and cultural legacy, both enriching online availability and fostering academic exchange. In his current role as “Archivist”, he keeps track of Grothendieck’s collected works and Grothendieck’s modern scholarship while also leading, for instance, transcription projects, thereby expanding accessibility to Grothendieck’s works and advancing editorial efforts. He also oversees, as Webmaster, the development, maintenance and accessibility of our institutional repository and online platform.

Research Associates

The Research Associates are a distinguished group of scholars that contribute to the CSG’s mission. Coming from a rich variety of different academic backgrounds, and spanning distinct domains of expertise relevant for modern Grothendieckian studies, they play a crucial role in shaping our projects and ensuring their scholarly rigor. These individuals are appointed jointly by the Coordinator of the CSG and the Scientific Council of the Grothendieck Institute.

Charles Alunni

Charles Alunni is a French philosopher, former professor at the École Normale Supérieure in Paris, where he founded and directed the Laboratoire disciplinaire Pensée des sciences. Alunni is well known for his work in the philosophy of science and has extensively studied the thoughts of notable figures like Gaston Bachelard and Gilles Châtelet. His research interests include the interplay between mathematics, philosophy, and linguistics. Alunni has authored several books and numerous articles on the history and philosophy of contemporary mathematics. He has also organized international conferences and edited several books, and is a member of the editorial board of the journal Revue de synthèse (Fondation pour la Science / Caphès). 

Myriam Anissimov

Myriam Anissimov is a prolific French author known for her novels and biographies centered around Jewish life in post-war France. Her literary journey has explored several avenues, in particular, she has prompted herself to chronicle the lives of celebrated Jewish writers and artists through monumental biographies. Throughout her career, she has received several awards, including the prestigious Ordre des Arts et Lettres from the French Ministry of Culture and the Prix Roland-de-Jouvenel de l’Académie Française for her novel “Les Yeux bordés de reconnaissance”. Anissimov’s unique voice offers profound insights into the political and everyday experiences of European Jews after the Holocaust, including the early life of Grothendieck as a Holocaust survivor. 

Benjamin Collas

Benjamin Collas is a French mathematics researcher at the Research Institute for Mathematical Sciences (RIMS) at Kyoto University in Japan. His work primarily focuses on arithmetic homotopy geometry. Collas’ work focuses on moduli stacks of curves, which he approaches by incorporating elements of Galois-Teichmüller theory, étale topology and motivic homotopy types theories, perverse sheaves theory, and, in collaboration with the Japanese schools, anabelian reconstructions. His contributions are among those stimulating the ongoing renewal of Grothendieck’s program and legacy in this field.

Following his 2024 text on anabelian geometry, Collas is now expanding his research to explore how Grothendieck’s practice of mathematics ensures a continuous and virtuous process of creation for the arithmetic geometer.

John Alexander Cruz Morales

John Alexander Cruz Morales is an Associate Professor at the Universidad Nacional de Colombia. His research spans various mathematical disciplines, including algebra, representation theory, mathematical physics, logic, and the history of mathematics.
He has authored numerous articles that have been published in international journals, and has written essays exploring the evolution of mathematical concepts and their philosophical implications. 
Cruz Morales has notably been conducting research on Grothendieck’s notion of space and its implications for contemporary mathematical theory.  

Jean-Pierre Marquis

Jean-Pierre Marquis is a professor in the Department of Philosophy at the University of Montreal, where he teaches logic and the philosophy of science. His research focuses on the philosophy and foundations of contemporary mathematics, and he has authored a book on the history and philosophy of category theory, as well as numerous articles in international journals. He is a Fellow of the Humboldt Foundation and the Center for Philosophy of Science at the University of Pittsburgh and has been a visiting professor at the Mathematics Research Center at Stanford University, the University of Paris Diderot, and Aix-Marseille University. He has served as Chair of the Department of Philosophy and Vice-Dean of Faculty Affairs in the Faculty of Arts and Sciences. Mr. Marquis’ expertise in Grothendieck’s studies, particularly in relation to the history of Category theory and the Bourbaki group, is widely acknowledged.

Colin McLarty

Colin S. McLarty is the Truman P. Handy Professor of Intellectual Philosophy and Mathematics at Case Western Reserve University. His research focuses on logic and the history and philosophy of mathematics. He has authored a book on the foundations of category theory and numerous articles published in international journals. His areas of expertise also include the philosophy of science, the history of philosophy – particularly Plato and Kant – and contemporary French philosophy. He has received several research grants and written numerous reviews of influential books in his field. His professional memberships include the Association for Symbolic Logic, the Philosophy of Science Association, and the American Philosophical Association. Mr. McLarty’s expertise in Grothendieck’s studies, especially regarding his reconception of geometry and number theory and its connections with logic and category theory, is widely recognized.

Frédéric Patras

Frédéric Patras is a prominent mathematician and researcher. He is a Director of Research at the CNRS (Centre National de la Recherche Scientifique) and works at the Laboratoire Dieudonné of the Université Côte d’Azur. His research interests span a wide range of fields, including combinatorial algebra and topology, history and philosophy of mathematics or quantum physics and noncommutative probability. He has authored several books in multiple languages, as well as numerous articles published in international journals. Patras has also contributed significantly to the academic community through his editorial work. He is an editor of the Annales de l’Institut Henri Poincaré D. Combinatorics, Physics, and their Interactions, as well as the chief editor of the Annals of Mathematics and Philosophy. He has also written and edited a wide range of books and articles on contemporary mathematical thought and its connections with other fields, specifically addressing the significance of Grothendieck’s work and ideas.
