Hi! I'm a Ph.D. student at the University of Washington, where I'm advised by Noah Smith and supported by an NSF Computer Science Graduate Fellowship. I'm also a student researcher on the Open Ecosystem team at Ai2, where I mainly work on language modeling.
Before my Ph.D., I worked on code generation at Google [x] and platform health at Twitter, and in a previous life I was a software engineer at Tableau and Google. See my CV for more details.
What I work on
Language modeling
I'm a core contributor to the Olmo model series at Ai2, where much of my work is on data-centric methods for improving model capabilities.
Environmental & societal impacts of AI
I also study what it costs to build and run language models, in energy, water, and carbon, from hardware manufacturing through deployment. More recently that includes the added footprint of reasoning models.
AI law & policy
I spend part of my time helping policymakers understand and address the impacts of AI. I've served as a public policy lead at Ai2 and as a member of the City of Seattle's Generative AI Policy Advisory Group, and organized a forum on the Future of AI with U.S. Senator Maria Cantwell's office. I've also written about legal questions raised by generative AI, such as liability, legal risk, and the First Amendment. You can find that work on my publications page.
