My research focuses on statistical and deep learning approaches to solving problems in spatial, urban and network data science.  I received my undergraduate degree in mathematics from IU Bloomington and my PhD in mathematics from UCSB.  I have held academic positions at UCLA, Santa Clara University and now IUPUI.  I was also director of data science at Metromile for 2 years and serve on the board of directors of PredPol.
