I am an Assistant Professor of Computer Science and Engineering at NYU's Tandon School of Engineering. My students and I are part of the Algorithms and Foundations Group.
My research is on the computational foundations of machine learning and data science. I study efficient methods for processing and understanding large datasets. We often combine ideas from theoretical computer science with tools from computational and applied mathematics.
I was previously a Research Instructor at Princeton. I completed my PhD in computer science at MIT, where I was fortunate to be advised by Jonathan Kelner. Before MIT I was an engineer at Redfin and before that I studied Applied Math and Computer Science at Yale.
For the next month I will be working with Jerry Li and the rest of the Machine Learning and Optimization Group as a Visiting Researcher at Microsoft Research Redmond.

If you are interested in working with me on research, I would encourage you to apply to NYU Tandon's PhD program in Computer Science. I will be taking new students in 2020 (December 2019 application). You should have a strong mathematical background, including in probability theory and linear algebra.
If you are interested in algorithms, machine learning, or data science in general, New York City is a unique environment for pursuing a PhD. Beyond NYU's broad investment in data science, the city offers unmatched access to top academic institutions,industry research labs, and startups.
I am also happy to advise masters or undergraduate research at Princeton or NYU. Reach out to learn about existing projects or let me know what topics you are interested in exploring.
Prototype code for some of the algorithms I work on is available through my GitHub page. I am always happy to answer questions about these implementations or to put you in touch with others who have implemented the methods in different languages and environments.
