I am a consulting professor at Stanford within ICME, conducting research and teaching courses targeting doctorate students.

I focus on Discrete Applied Mathematics, Machine Learning Theory and Applications, and Large-Scale Distributed Computing.

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


Teaching CME 305: Discrete Mathematics and Algorithms (MS&E 316)

Teaching MS&E 317: Algorithms for Modern Data Models (CS 263)

Leading SMACC Consulting and ICME Computational Consulting

Reviewer for JMLR, PRJ, NIPS, and ECML PKDD

I contribute to the Apache Spark project, and teaching Spark workshop and Spark class.
