I am a Tenure-track Assistant Professor in the Department of Statistics at University of California, Los Angeles. Previously, from July, 2017 to June, 2019, I was Neyman Visiting Assistant Professor in the Department of Statistics at University of California, Berkeley. Before that, I earned a Ph.D. in statistics at The University of Texas at Austin in May 2017 under the supervision of Prof. James Scott. My undergraudate degree was a B.S in Mathematics completed at CIMAT in April 2013, advised by Prof. Daniel Hernandez-Hernandez. A copy of my CV can be found here.
