About [CV]

I am currently a third-year PhD student in Manning College of Information & Computer Sciences, University of Massachusetts Amherst, asvised by Prof. Hamed Zamani . My research interests are primarily focus on IR and NLP, especially on Dense Retrieval and Generative Retrieval.
Before PhD, I got my CS master degree from University of Utah, advised by Qingyao Ai. And I got my Math bachelor and master degrees from Nankai Univeristy and University of Wisconsin Madison respectively.
