Research Interests

I am broadly interested in online and reinforcement learning, primarily focusing on time-varying models and algorithms for learning and exploiting structure in large-scale data. Recently I have begun working on developing and applying time-varying online reinforcement learning approaches to just-in-time adaptive interventions in mobile health.

Bio

I am currently a postdoctoral researcher at the Department of Statistics at Harvard University, starting September 2017. University of Michigan, starting in January 2017. I received my PhD in Electrical Engineering (Signal Processing) at the University of Michigan in January 2017, advised by Alfred Hero III and Shuheng Zhou. My B.S. (magna cum laude) and M.S. degrees in Electrical Engineering were received from Wright State University in 2011 and 2012 respectively. Previously I was a postdoc at the Department of Statistics, University of Michigan January-August 2017, and have had research internships at the US Air Force Research Laboratory (2011, 2012, 2013, 2014) and at M.I.T. Lincoln Laboratory (2015).
