I am an assistant professor in the Computer Science department of Rensselaer Polytechnic Institute. My research focuses on using randomization to reduce the computational costs of extracting information from large datasets. My work lies at the intersection of randomized algorithms, numerical linear algebra, high-dimensional probability, and machine learning.

I earned my PhD in applied and computational mathematics at CalTech under the supervision of Prof. Joel Tropp, in 2013. From 2013 until 2015, I was a member of the machine learning research group at eBay. Following that I was a postdoctoral fellow in the AMPLab at UC Berkeley and a member of the International Computer Science Institute. I joined RPI in January of 2017.

I am currently seeking PhD students.


In the fall of 2017, I am teaching CSCI6220/4030, "Randomized Algorithms". See the website for the syllabus and assignments.

In the spring of 2017, I taught a course related to my research, CSCI6971/CSCI4971, "Large Scale Matrix Computation and Machine Learning". See the syllabus.
