I am a 5th year Ph.D. student at the Department of Statistics at the University of Washington. I am advised by Emily Fox and am a member of the MODE Lab. I am fortunate to be funded by an IGERT fellowship in Big Data and Data Science.
My research interests are in 1) statistical machine learning approaches to multivariate time series and 2) scalable computation for rich probabilistic models.
