### Dr. Leonid Ryvkin

I am a mathematician working in the field of multisymplectic geometry. My research interests include differential and symplectic geometry, homological algebra and algebraic topology.

I recently completed my doctorate and will start working at the IMJ-PRG in Paris this October. A brief description of my research project can be found on the website of the RUB Research School, which funds the project.
