About Me
I am a 4th year PhD student at Duke University, advised by Katherine A. Heller. I have been a visiting student researcher at UC Berkeley with Michael I. Jordan since August 2018. I have also been a student researcher at Google Brain since January 2019.
I am interested in the design and theoretical analysis of probabilistic inference algorithms. More generally, I strive to better understand uncertainty quantification which I believe is crucial for robust decision making and efficient lifelong learning in a dynamic environment mirroring our physical world.
I have been fortunate to receive the following fellowships: Facebook Emerging Scholar (2019-2021, declined), Pratt-Gardner Graduate Fellowship (2017-2019).
During my Ph.D., I have spent wonderful summers interning at Google Brain (2019) and Google Research NY (2018).
Before moving to Duke, I graduated with a Bachelor's and a Master's degree in Computer Science from Princeton University, where I was advised by
Barbara E. Engelhardt.
