I study programming models and architectures for Quantum Computers. I am broadly interested in Computer Architecture, Quantum Computing, and Secure and Sustainable Systems. I am an Assistant Professor in the School of Computer, Data, & Information Sciences, at the University of Wisconsin-Madison, where I lead QUEST Research Group. Our team explores various disciplines within the system and architectural design of quantum computers and focuses on developing new abstractions, architectures, and tools for quantum and classical computing systems.
