Reza Zadeh

I am a Ph.D. Candidate in Computational Mathematics at Stanford. I received a masters from the School of Computer Science at Carnegie Mellon University. Before that I completed a bachelors at the University of Waterloo. During undergrad I worked at Google Research.

Currently interested in Discrete Applied Mathematics, Machine Learning Theory and Applications, and Big Data.

At NIPS 2009 I coorganized a Workshop on Clustering Theory. I am a reviewer for JMLR, PRJ, NIPS, and ECML PKDD.

I am President of the Stanford ICME Computational Consulting Student Group.

In Winter 2014 I will be teaching CME 305 of the ICME core courses, as the primary instructor, targeting doctoral students with a strong foundation in mathematics.

For fun, I fly planes as a private pilot, climb rocks as a PCIA instructor, and run.
