Peihan Miao 缪沛晗

I am an Assistant Professor in the Department of Computer Science at Brown University.

Previously, I worked as an Assistant Professor at the University of Illinois Chicago. Before that, I was a Research Scientist at Visa Research. I received my Ph.D. from UC Berkeley in 2019 under the supervision of Sanjam Garg and my BS degree from ACM Honors Class at Shanghai Jiao Tong University. Here is my CV.

My research interests lie broadly in cryptography and security, with a focus on secure multi-party computation (both theoretical and applied). My research is supported by the NSF SaTC award, a DPI Science Team Seed Grant, and a Meta award.

I am looking for motivated PhD students and postdocs. Please send me an email if you are interested in working with me.
