[CV] (Last update: 10/04/2020)
I am an assistant professor in the computer and information science department at the University of Michigan-Dearborn. My research focuses on building practical tools and techniques to expose various performance bottlenecks and optimization opportunities in software. Since the complexity of computational systems is increasing, designing a performant software/hardware is becoming more challenging. To address these challenges, I develop practical “program analysis tools”. I did my PhD with Xu Liu at the College of William and Mary, developing lightweight memory profiling techniques to identify performance inefficiencies.
