Research My thesis research was on the topic of finite mixture models, statistical models for data from populations believed to be comprised of two or more subpopulations mixed together but where we have no data on the group membership for individuals.  The group identifier can be treated as missing data, parameter estimation can be done using some interesting missing data techniques, and we can make inference about the parameters of the component populations as well as the mixing proportions using resampling methods.

My current interests are in assessing the efficacy of educational interventions using randomized trials.
