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.
Research
I lead the QUEST Research Group at the University of Wisconsin Madison. To learn more about our latest projects on Quantum Computing Systems and Architecture, please visit – https://quest-lab.cs.wisc.edu/
I am always looking for motivated students. If you are interested in working with me, please email me your CV and a short paragraph on what you want to work on and how it connects to our existing research projects.
