I am an Assistant Professor of Computer Science at the University of Colorado Boulder, where I lead the Quantum Architecture, Systems, and Applications Research (QUASAR) Lab and serve as Director of the Center for Quantum Computing (CQC).
My research focuses on building reliable, scalable, and secure quantum computing systems through software–hardware co-design. My interests span quantum computer architecture and systems, compilers and runtime systems, quantum error correction and real-time decoding, fault-tolerant computation, distributed quantum computing, and secure quantum computation.
Quantum optimization is a central focus of my work, encompassing algorithms, domain-specific systems, and emerging accelerators. I also explore the synergy between quantum computing and AI/ML, asking how quantum computation can expand what AI can learn, reason about, and solve. Another interest is the intersection of Boolean satisfiability (SAT) and quantum computing. My group develops quantum systems to tackle real-world problems, with a particular emphasis on healthcare, including drug discovery and formulation.
I am a recipient of the NSF CAREER Award. Before joining CU Boulder, I was a postdoctoral researcher at Georgia Tech and an NSF/CRA Computing Innovation Fellow. I earned my PhD from the University of Maryland, Baltimore County.
I am looking for highly motivated graduate and undergraduate students to join the QUASAR Lab.
