I am a fourth year Ph.D. student in the Theory of Computation Group at MIT's Computer Science and Artificial Intelligence Laboratory. I am lucky to be advised by Nancy Lynch and partially supported by an NSF Graduate Research Fellowship. I study algorithms and am especially interested in randomized methods for linear algebraic computation and data analysis. I am also interested in better understanding randomized computation and algorithmic robustness by studying computation in biological systems.

Before MIT, I studied Computer Science and Applied Mathematics at Yale University and worked as a web developer at Redfin.

Here are my Google Scholar profile, my CV, and my rather sporadic and unfocused Quora profile.

The website for our Spring 2017 reading group on Realistic Distributed Algorithms (including distributed computation in biological systems) can be found here.

Here are a few writeups, notes, and talks. Some are super basic, but sometimes that's good.

Chebyshev Polynomials in TCS and Algorithm Design, outline of a talk I gave at the MIT Theory student retreat on the many applications of Chebyshev polynomials to upper and lower bounds in Theoretical Computer Science.

Subspace Scores for Feature Selection in Computer Vision, final project report where we test our column sampling algorithm for k-means/PCA dimension reduction (found here) and explore its use as a general feature selection technique.

Applications of Linear Sketching to Distributed Computing, slides for a talk I gave at our Theory of Distributed Systems seminar. High level overview of linear sketching, recent work on k-means clustering and spectral sparsification, and applications to distributed data analysis.

Graph Sparsification and Dimensionality Reduction, final project report for Jelani Nelson's Algorithms for Big Data class.

Linear Regression and Pseudoinverse Cheatsheet, since there are a lot of ways to explain the pseudoinverse and sometimes I forget the details.

Big-O and Asymptotic Notation Cheatsheet, since sometimes I forget even this.

Fast Approximation of Maximum Flow using Electrical Flows, undergraduate Applied Mathematics senior project report. I was fortunate to be advised by Dan Spielman for both my senior projects. They were my first introduction to research in computer science and the reason I decided to go to graduate school.

Graph Construction Through Laplacian Function Optimization, Computer Science senior project report.

I've worked on a lot of projects, some more serious than others.

I built this Rap Collaboration Graph, which gives a visualization of musical collaborations in hip hop. Unfortunately, colors are only rendering in Safari right now, it looks fuzzy on retina displays, and the data is about a year out of date. But I promise I'll get to it.

I had a lot of fun helping build the first version of a site that sold buffalo chicken sandwiches. It's gotten a major facelift and evolved into Crunchbutton, but here is a screenshot of the original One Button Wenzel in its glory

My friend Charlie and I once built an AI to play Transport Tycoon Deluxe. Here is a poster describing the project.

In college I also had a lot of fun working on Yale's Formula Hydrid Racecar Team.

I love to ski, and a long time ago, my brother Chris and I used to hand build custom skis. Our first pair had maple/poplar cores, varnished wood sidewalls, and flex comparable to a pair of 2x4s. Our second iteration has more precisely shaped pine cores, a smoother top sheet, and a much smoother flex. The tips delaminated once, but we riveted them together and still ski on them today! Here's an old forum post on SkiBuilders.com with more pictures of our setup and first pair.
