My work is focused on: 1) measuring the impact of data archiving and curation activities; 2) studying networks in data-sharing communities; and 3) enhancing data discovery through machine learning and natural language processing. My research has been supported by an NSF grant, Transforming Data Discovery Through Behavior Modeling and Recommendation, investigating the potential to connect researchers to relevant data via recommender systems.

I hold a Ph.D. in Geography with an emphasis in Information Technology and Society from UC Santa Barbara. From 2020-2023, I was a Postdoctoral Research Fellow at the University of Michigan's Inter-university Consortium for Political and Social Research (ICPSR) and a Lecturer in the Master of Applied Data Science program at the University of Michigan School of Information. My other interests include statistical and spatial analysis, information visualization, and Semantic Web technologies.
