Chuhao Huang

I am a second-year Ph.D student in mathematics at École Normale Supérieure (ENS-PSL), working under the supervision of Olivier Benoist. Before, I obtained a master's degree in mathematics from ENS-PSL and Sorbonne Université, and a bachelor's degree in mathematics from Peking University.

Research interests

My research interests lie at the interface between algebraic topology and algebraic geometry, with a particular focus on applying techniques from cobordism theory to the study of algebraic cycles.

"It was my lot to plant the harpoon of algebraic topology into the body of the whale of algebraic geometry."

Seminar

I'm co-organizing Séminaire Mathjeunes, a seminar which focuses mainly on geometry (algebraic, complex, motivic, etc.) and number theory. The speakers are typically PhD students and postdocs, and the audience consists mainly of PhD and master's students.

Please feel free to contact me if you would like to be added to the mailing list or if you are interested in giving a talk.
