I’m a PhD student at the University of Utah, advised by Vivek Srikumar. I work on problems at the intersection of natural language processing and machine learning.

Prior to joining Utah’s NLP Lab, I worked as a senior machine learning engineer at The Washington Post, where I trained and deployed models for revenue optimization and personalized advertising. Before my time at the Post, I was a machine learning engineer at Alion Science and Technology, where I worked on multilingual information retrieval. I received my undergraduate degrees in Computer Science and Linguistics from the University of Maryland in 2019.

My work is supported by the National Science Foundation CSGrad4US Fellowship.
