Hang Zhou
Professor at École Polytechnique
zhouhang32 (at) gmail.com
I am a professor in the Computer Science department at the École Polytechnique.
My research is mainly on combinatorial optimization, graph algorithms, and operations research.
I received my PhD from the École Normale Supérieure de Paris.
I was very fortunate to have Claire Mathieu as my PhD advisor.
Afterwards, I was a postdoctoral researcher at the Max-Planck-Institut für Informatik in Germany, and
I was very lucky to be hosted by Kurt Mehlhorn.
I received the Lise Meitner Award for excellent women in computer science.
ICPC: I was the coach of the École Polytechnique team that won the championship in European programming competition (SWERC), the first championship in École Polytechnique's history, as well as eight medals, and three times advanced to the World Finals.
Member of program committees: SOSA'23, STACS'24.
