About me

I’m a 5th-year Ph.D. student in artificial intelligence at Stanford advised by professor Percy Liang in the Stanford Natural Language Processing (NLP) Group. I completed my undergraduate degree in mathematics at Duke University, where I was mentored by professors David Dunson and Alex Hartemink.

In our research, my collaborators and I have developed new methods for text generation, program synthesis from natural language, and knowledge base completion.

Long-term, I’m excited about leveraging technology to help people with high-stakes information needs (e.g. a patient trying to diagnose their rare disease, or a legislator trying to predict the impact of a new policy).

• Areas of interest: artificial intelligence, machine learning, deep learning, natural language processing, semantic parsing, reinforcement learning, statistics

Other projects

Presentations and tutorials

• Why naive cross-validation can fail for feature selection.
• Presentation on selection and multiple hypothesis testing, based on several great lectures by Emmanuel Candes.
• Presentation on random matrices, prepared for Percy Liang’s reading group.

Libraries

Unfortunately, much of my recent code is closed-source at the moment, but I’m working on getting it cleaned up and ready for others to use! The following projects are fairly old/out-of-date, but I’m keeping them around in the odd chance they might be of use to someone somewhere.

• Simple Speech Recognition - 2013
  A complete speech recognition system you can deploy with just a few lines of Python, built on CMU Sphinx-4.

• Gitmemoizer - 2013
  Automagically memoize any function and save results to disk (for Java).

• Giterable - 2013
  A Java package for iterating through files in your Git repo and loading them.

Collaborators

I have had the privilege of working with and learning from great mentors and collaborators, including:

• Percy Liang, Assistant Professor of Computer Science at Stanford
• Panupong (Ice) Pasupat, Ph.D. Student in Computer Science at Stanford
• Jakob Uszkoreit, Senior Staff Software Engineer at Google
• Richard Socher, Chief Scientist at Salesforce
• David B. Dunson, Professor of Statistics at Duke
• Debdeep Pati, Assistant Professor of Statistics at Florida State
• Alex Hartemink, Professor of Computer Science at Duke
• Ronald Parr, Professor of Computer Science at Duke

I’ve enjoyed mentoring younger students, including:

• John Miller, undergraduate in Computer Science at Stanford (enrolling in PhD program in Fall 2017)
• Justin Fu, MS in Computer Science at Stanford, currently PhD student at UC Berkeley
• Dora Demszky, undergraduate in linguistics at Princeton (enrolling in PhD program in Fall 2017)
• Evan Liu, undergraduate in Computer Science at Stanford

Finally, I think the following entities are pretty swell:

• Doug Engelbart. We still need to finish this guy’s mission.
• Wikipedia and Freebase.
• Jon Kabat-Zinn. For bringing scientific attention to the study of mindfulness.
• The Bill & Melinda Gates Foundation. I think they make a huge impact by bringing an investor’s mindset to important and good causes.
