Satyanad Kichenassamy was born in Paris in 1963, graduated from the Ecole Normale Supérieure in Paris and obtained his doctorate under the direction of Haïm Brezis. He is currently Full Professor of Mathematics at the Université de Reims Champagne-Ardenne, in the CNRS Mathematics Research division there, of which he was the director from 2004 to 2007. He has previously been on the faculty of New York University, and of the University of Minnesota. He has also spent a year at the Max Planck Institute in Leipzig. He has given a lecture series at EPHE (Paris) in 2021-22 and will deliver another one in 2023-24. He works in Mathematics, History and Indology, and has solved several long-standing problems in each of these fields. He introduced the method of Fuchsian Reduction in Nonlinear Analysis, the method of Conformal Snakes in Computer Vision, and the notion of apodictic discourse in History of Science. He has shown that major Indian mathematicians have encoded derivations and even definitions through the discursive structure of their works, so that unless one performs the appropriate textual analysis, they appear to contain unsupported statements.
