About me
I currently work as a machine learning engineer at Captricity.
Before that, I was a PhD student in the Medical Vision Group at CSAIL, where I worked with Polina Golland. For my PhD, I worked on applications of machine learning and artificial intelligence to problems in medical imaging. I was 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.

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: Chi-squared 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
- Good-Turing Estimators, from McAllester and Schapire's On the Convergence Rate of Good-Turing Estimators
- Streaming Algorithms: Part 1 and Part 2, from Muthukrishnan's Data Streams: Algorithms and Applications
- In 2015, I received the Goodwin Medal, awarded by MIT to one or two graduate students each year for teaching performance that is "conspicuously effective over and above ordinary excellence."
- I taught a short course titled 6.S085, Statistics for Research Projects in January 2012 (with my colleague Finale Doshi-Velez), 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 from the EECS department at MIT, 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 brand-new undergraduate course on inference! Along with my fellow TAs, George Chen and Gauri Joshi, we made Khan Academy-inspired 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.
