I'm a Lead Research Scientist/Manager at Snapchat Research. I live in San Diego, CA.

My PhD thesis advisor was the ingenious William W. Cohen. I have worked at Microsoft, Qualcomm Research, Inome and Ericsson R&D. I'm interested in applied research interfacing Machine Learning, Natural Language Processing, Information Retrieval, Text Mining, Data Mining and AI.
