About me
I'm a Ph.D. student working with Polina Golland in the Medical Vision Group in CSAIL. My research interests are in machine learning and artificial intelligence; in particular I'm working on applications of these to problems in medical imaging. I'm currently funded by the NSF Graduate Research Fellowship.
I was an undergraduate in EECS at UC Berkeley. While I was there I worked with Stan Klein's Visual Processing Lab on signal processing in vision science, and with Dan Garcia and Brian Harvey on a curriculum development project involving parallelism in introductory computer science courses.
You can also find me on github.

Teaching
List of notes and writeups I've made: A series on introductory practical statistics, with a focus on how and when to use different statistical techniques:
 1: Introduction and definitions
 2: Confidence Intervals and Classical Hypothesis Testing
 3: Linear regression fundmentals
 4: Advanced linear regression: robustness and sparsity
 5: Nonparametric tests (with fewer assumptions) and model evaluation
 6: Categorical data: Chisquared tests and ANOVA
 7: Principles of experimental design
 Primers on a few key topics in probabilistic inference and machine learning:
 Notes for seminars, made in collaboration with my colleage Matt Johnson:
 Differential Geometry, from Kuhnel's Differential Geometry
 GoodTuring Estimators, from McAllester and Schapire's On the Convergence Rate of GoodTuring Estimators
 Streaming Algorithms: Part 1 and Part 2, from Muthukrishnan's Data Streams: Algorithms and Applications
 I taught a short course titled 6.S085, Statistics for Research Projects in January 2012 (with my colleague Finale DoshiVelez), January 2013, and January 2014 (with my colleague George Chen), and again in January 2015. I also wrote up a series of notes (soon to be compiled into a small book), which you can find at the course website.
 In 2013, I received the Frederick C. Hennie III Teaching Award, awarded to a few graduate students in the department each year for teaching excellence.
 I was a TA for 6.s080: Introduction to Inference in Fall 2012. This was a brandnew undergraduate course on inference! Along with my fellow TAs, George Chen and Gauri Joshi, we made Khan Academyinspired videos summarizing recitation topics. If you're at MIT, you can view my teaching ratings. I also wrote up some notes on course topics, which you can find above.
 I was a TA for 6.438: Algorithms for Inference in Fall 2010. If you're at MIT, you can view my teaching ratings.
 I was a TA for 6.041: Probabilistic Systems Analysis and Applied Probability in Fall 2008. If you're at MIT, you can view my teaching ratings.
 In 2008, I received the Outstanding Graduate Student Instructor Award, granted to several TAs within each department across UC Berkeley each year. The same year, I received the EECS Outstanding Graduate Student Instructor Award, granted to one or two outstanding TAs within the department each year.
 I was a TA for CS61A: Structure and Interpretation of Computer Programs, an introductory computer science class, from Summer 2006 to Spring 2008. You can see my teaching ratings.
