Samson Zhou

Hi, I'm a Postdoctoral Fellow at Carnegie Mellon University, hosted by --davidwoodruff--. My current research interests are sublinear algorithms, machine learning, and password hashing.

Previously, I was a postdoc at Indiana University hosted by --grigoryyaroslavtsev--, a postdoc at Purdue University hosted by --jeremiahblocki--, and a graduate student at Purdue University advised by --gregfrederickson-- and --elenagrigorescu--.

Here are some of my favorite links.
