research interests

CUNY geometric analysis seminar

Riemannian geometry: integral geometry including isosystolic inequalities and their generalizations, radial curvature

I co-organize the CUNY geometric analysis seminar with Prof. Bianca Santoro. It meets at the CUNY Graduate Center on most Thursdays from 3 pm to 4 pm.

The schedule of speakers can be found on the seminar web page.
