My research interests span the areas of artificial intelligence, machine learning, optimization, and high-performance computing. My team and I focus on advanced research areas in AI for Science at Argonne including scalable automated machine learning, metalearning, reinforcement learning, geometric machine learning, and neuromorphic computing.

I am a recipient of U.S. Department of Energy 2018 Early Career Award. I lead the AI area in RAPIDS2: A SciDAC Institute for Computer Science, Data, and Artificial Intelligence. I lead the research and development of DeepHyper, a scalable automated machine learning package for DOE leadership-class systems.

I am a Fellow in the Northwestern-Argonne Institute of Science and Engineering of the Northwestern University. I am also a Scientist At-large in the University of Chicago Consortium for Advanced Science and Engineering (UChicago CASE).

Previously,

• 2017--2020: Computer Scientist, MCS & LCF Divisions, Argonne National Laboratory
• 2014--2018: Fellow, Computation Institute, University of Chicago
• 2014--2017: Assistant Computer Scientist, MCS & LCF Divisions, Argonne National Laboratory
• 2010--2013: Postdoc, MCS Division, Argonne National Laboratory
