I am an Assistant Professor in the Department of Computer Science at the University of North Carolina, Chapel Hill.
I also spend one day a week as a Faculty Researcher at Hugging Face.
Much of my recent research focuses on machine learning algorithms for learning from limited labeled data, including semi-supervised, unsupervised, and transfer learning.
