I am a researcher at the University of Pennsylvania. My current appointment is with the Department of Biostatistics, Epidemiology and Informatics (DBEI) at the Perelman School of Medicine.  I am a senior member of the Health Language Processing Lab (HLP), which is part of the Institute of Biomedical Informatics.

My research interests include natural language processing (NLP), social media mining (SMM), applied machine learning (ML) and biomedical informatics. I believe in reproducible and community driven research, and always try to publicly publish my code (e.g., here and here) and data (e.g., here and here).

I teach professionally and as a hobby. I frequently run specialized workshops on NLP, SMM and applied ML to teach/train researchers and students from a wide spectrum of educational backgrounds.

I am available (and typically enthusiastic) to provide professional consultation, run specialized workshops, or talk about potential applications of NLP and applied ML using big and small data. Feel free to contact me via email.
