About Me
I am a postdoctoral researcher at the Statistical and Applied Mathematical Sciences Institute. My current research projects are on anomalous diffusion and the statistics of extremes/change-point detection. My past research projects were in image segmentation, atomic force microscopy, and landscape modeling.
My Ph.D. advisor was Andrea Bertozzi. I was also a visiting student at ENS Cachan, France under the direction of Jean-Michel Morel. For more information about me or my research projects, please see my CV.
