I am a 5th year PhD student in computer science at MIT, graduating in the spring of 2018.
I am fortunate to be advised by Jonathan Kelner. My research is on the algorithmic foundations of data science and machine learning. I study computational methods for processing large graphs and matrices.
I draw on tools from theoretical computer science, numerical linear algebra, and optimization, with a focus on methods that adapt to modern computational environments, including streaming and distributed frameworks.
Our paper on Recursive Sampling for the Nyström Method appeared in NIPS 2017. Code for the algorithm is available on GitHub. Also check out our recent SODA 2018 paper on the Lanczos method: it pins down the stability of Lanczos for applying matrix polynomials, proving correct our method for Principal Component Regression that combines Lanczos with any iterative or stochastic system solver.

Prototype code for some of the algorithms I work on is freely 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.
If you're an MIT affiliate running into algorithmic problems in your research, check out our "Algorithms Office Hours". You can submit a description of your project and we'll set you up to meet with algorithms researchers in CSAIL who may be able to offer some guidance.
I'm an advisor with the EECS Graduate Communication Lab. We offer peer reviewing and coaching for research papers, fellowship and job applications, CVs, talks, and any other writing task or presentation. MIT affiliates can schedule an appointment with me or any other advisor here.
