I’m a second-year PhD student at the Center for Language and Speech Processing at Johns Hopkins University, advised by Benjamin Van Durme and Dawn Lawrie. I am broadly interested in natural language processing (NLP), information retrieval (IR), and machine learning (ML). My research is graciously supported by a NSF Graduate Research Fellowship.

My current research is situated between the NLP and IR fields, where I work to improve how models find and understand knowledge. Specifically, I’m interested in multilingual retrieval and question answering (QA), robust open-domain QA across noisy sources and different domains, and efficient methods for IR and QA.

Previously I graduated with my Bachelor’s degree from Brigham Young University in computer science and statistics, where I was advised by Kevin Seppi and Quinn Snell.

In the past, I’ve spent time interning with several great mentors: with Matthias Sperber at Apple AI/ML in summer 2020 and 2021 and with Matt Gardner and Matthew Peters at the Allen Institute for Artificial Intelligence (AI2) in the first half of 2020.
