Research

I am currently interested in spatial-temporal point processes and nonparametric statistics. Specifically, I have done some work with self-exciting point processes and how they apply to things like gang related crimes in Los Angeles and insurgent activity in Iraq.

 

 

Papers

    I was a mentor with George Mohler for an REU in the summer of 2009. The undergraduates in our group published the following:
