I am an assistant professor of Computer Science at the University of Virginia. I lead the Responsible AI for Science and Engineering (RAISE) group where we make advances in artificial intelligence with focus on two key themes:
Foundation Models for Science and Engineering: We develop the foundations to blend predictive and generative models and neuro-symbolic reasoning for complex scientific and engineering problems.
Trustworthy & Assured AI: We analyze the assurance of AI systems in support of decision-making and learning tasks, focusing especially on privacy, safety, and fairness.

My research has been generously supported by various projects from the National Science Foundation, a Google Faculty Research Award, an Amazon Research Award, a Cohere For AI Research Grant Program, a NVIDIA Academic Grant Program Award, the LaCross Institute, and the University of Virginia.

For more details, please see my papers and short bio

Opportunities for Undergaduates Students

I regularly accept undergaduates and graduates interns who are willing to work on Responsible AI or Differentiable Optimization topics. See this page for current projects available.

If you are interested in working with us, send me your CV and interests and make sure you check our latest work!
