I am a founding faculty member in the new Information Science department in the College of Media, Communication, and Information at CU-Boulder (see: CU vs. UC). I received a Ph.D. in Computer Science from Johns Hopkins University in 2015, and a B.S. in Computer Science from the University of Illinois at Urbana-Champaign in 2009. See my CV. My research is at the intersection of text analysis and health/social science. On the methodological side, I research machine learning and natural language processing, and in particular I develop methods in topic modeling, which I use to discover patterns in large text datasets. On the applied side, I study social media to learn about human behavior, especially in the context of public health.
I am no longer in academia as of May 2020. I am not currently responding to reviewer requests.
