Xiaonan Ma

Ma was born in 1972 in Zhejiang, China. He graduated high school with a maths score of 117 out of 120.^[1]

Ma obtained his bachelor degree from Wuhan University. He then received his Ph.D. in 1998 under the direction of Jean-Michel Bismut at Paris-Sud University with a thesis entitled Formes de torsion analytique et familles de submersions.^[2]

Ma was a researcher at the French National Centre for Scientific Research from 2001 to 2007, working at the Centre de mathématiques Laurent-Schwartz of École Polytechnique. After the habilitation in 2005 (Théorie de l'indice local et applications) he became a professor at the University Paris VII (Denis Diderot) in 2007.^[3]

Ma had a postdoctoral position in the group of Jochen Brüning at the Humboldt University of Berlin and was visiting Professor at the University of California, Santa Cruz. He was junior member of the Institut universitaire de France from 2009 to 2014. He is member of the international Faculty of the University of Cologne.^[4]

In October 2024, it was reported that Ma would join Nankai University where he will serve as chair professor at the Chern Institute of Mathematics.^[1]

The research themes of Ma encompass global analysis and local Atiyah–Singer–index theory (analytic Ray–Singer torsion, Eta forms, elliptic genera), Bergman kernels and geometric quantization. He is editor of Science in China A (Mathematics)^[5] and of International Journal of Mathematics.^[6]

Ma was awarded together with George Marinescu the Ferran Sunyer i Balaguer Prize in 2006 for the book "Holomorphic Morse inequalities and Bergman kernels".^[7] He was an invited speaker at the International Congress of Mathematicians in Hyderabad 2010 (Geometric quantization on Kähler and symplectic Manifolds).^[8] Ma received in 2017 the Sophie Germain Prize.^[9] He received in 2022 the Gay-Lussac-Humboldt Prize^[10][11]
