I am a Ph.D. student in the Computer Science Department at North Carolina State
University studying artificial intelligence. I graduated from Eastern Washington University
with a B.S in Computer Science and a focus in parallel and cloud computing.
My research interests broadly cover fairness and accountability in machine learning,
multimodal learning analytics, as well as AI tools for education. I am particularly interested
in the design of tools for educators that provide adaptive support in collaborative learning
environments.
