My name is Zilu Ma and I am a fifth year PhD student in Mathematics at UCSD. My advisors are Professor Bennett Chow and Professor Lei Ni. I did my undergraduate studies at Xi'an Jiaotong University.

My main research interests lie in geometric analysis, and more specifically, intrinsic and extrinsic geometric flows, with an emphasis on Ricci flow and its applications to geometry and topology. I am also interested in some other geometric PDEs, such as Cheeger-Colding theory and its applications to Riemannian and Kaehler geometry.

Here is my CV (last updated in May 2022).
