Suqi Liu

I am a Postdoctoral Research Fellow in the Department of Biomedical Informatics at Harvard Medical School working under Professor Tianxi Cai. I received my Ph.D. from Princeton University advised by Professor Miklos Racz.

My research interests lie broadly at the intersection of probability, statistics, and combinatorics. Specifically, I study random graphs with latent geometric structure with application to biomedical networks.

Previously, I was a graduate student at UC San Diego advised by Professor Lawrence Saul, co-advised by Professor Geoffrey Voelker and Professor Stefan Savage. I completed my undergraduate study at Tsinghua University where my thesis adviser was Professor Jun Zhu.

I did internships at Google working on Google Knowledge Graph and Google Ads in the Bay Area during the summers of 2016 and 2018. I also interned at Microsoft Research Asia from April to November 2012.
