I am a Professor of Computer Science and Engineering at the University of Michigan with expertise in computer architecture, hardware-software co-design, trustworthy computing, hardware security, parallel systems, compilers, GPUs, accelerators, memory systems, and genomics computing. My current work focuses on hardware-rooted security for agentic AI, parallel systems for genome sequencing, and generative AI techniques for producing efficient parallel code for modern accelerators. My research has been recognized with an NSF CAREER Award, best paper awards at ASPLOS and ISPASS, four IEEE MICRO Top Picks awards, and induction into the ISCA, ASPLOS, and PLDI Halls of Fame. My work has also had practical industry impact: my record-and-replay research helped shape tools such as Microsoft WinDbg’s iDNA and Intel PinPlay, which have been used for debugging, architectural simulation, and software development. I am an inventor on multiple issued U.S. patents, including U.S. Patent Nos. 8,561,...
