## Chenglong Yu

I am a Hans Rademacher Instructor of Mathematics at University of Pennsylvania.

My research is in algebraic geometry and differential geometry. I am interested in the geometry and arithmetic properties of Calabi-Yau varieties, especially the differential systems arising from Calabi-Yau families. I am also interested in moduli of K3 surfaces and cubic fourfolds.
