Michaël Liefsoens

I am a mathematician specializing in geometry and a physicist dedicated to exploring the building blocks of life.

Research interests

My mathematical research interests include, but are not limited to, the differential geometry of submanifolds, and Lie groups and Lie algebras. Furthermore, my physics research interests include the physics and topology of DNA and epigenetics.
