I am a Data Scientist at Google. Previously, I was a postdoctoral researcher in the Department of Statistics at Carnegie Mellon University, working with Aaditya Ramdas and Alessandro Rinaldo. I recently graduated from the same department with a Ph.D. in Statistics.
My research interest lies in understanding the sequential and adaptive nature of data analysis. I study how commonly used statistical inference procedures behave under the presence of an analyst’s data-dependent choices. My current projects focus on designing and analyzing nonasymptotic sequential testings and online change-point detection procedures.
