Hello and welcome to my webpage


My primary research interest is making data-driven decisions within service systems, with an emphasis on healthcare delivery. My goal is to combine empirical/statistical analysis with data-driven modeling to do high impact research.


I am always looking for opportunities for research collaborations with industry partners (e.g., physicians, nurses, hospital administrators). If you have any interesting ideas or problems, please email me.


Here is more details about our Ph.D. program.
