Research Interests
My research is in machine learning, specifically graphical models for time series analysis and learning from high-dimensional sparse data.  My thesis work develops a new probabilistic time series model inspired by the functional Magnetic Resonance Imaging (fMRI) domain called Hidden Process Models.

Personal
I play ultimate frisbee in leagues, and with a travelling women's team.  I also enjoy racquetball, knitting, and cooking.  My husband and I have two dogs, Luna and Sola, who never fail to turn our hiking/camping trips into adventures.
