About MeI am a postdoctoral scholar at the University of California, San Diego under the Data Science Postdoctoral Fellowship program, which is co-sponsored by ITA, Calit2, the Qualcomm Institute, CSE and ECE. My work is in the area of statistical machine learning. Previously, I was a postdoctoral scholar in Lise Getoor's LINQS research group at UCSC, and I graduated from Padhraic Smyth's DataLab group at UCI. For more information, see:
- My publications, including links to code and slides.
- My Courses.
- My CV (or email for a more up to date version).
- My PhD thesis has a lot of tutorial-style introductory material on probabilistic latent variable modeling, which you may find useful.
I am on the job market for Fall 2017! Please contact me at the email address above for more information.
Research InterestsMy research interests are in both applied and foundational machine learning, focusing on probabilistic models and Bayesian inference algorithms to learn them from data. My work aims to promote the practice of latent variable modeling for applied research in disciplines such as computational social science and the digital humanities. I develop models and algorithms for finding interpretable latent structure in data such as social networks and text, which may provide a window into human nature.
