Biography
I am currently an AI Compiler Engineer at Microsoft, where I am also involved in the MAIA project. Before joining Microsoft, I earned a Ph.D. in Computer Science from Georgia Institute of Technology, where I conducted research under the guidance of Prof. Vivek Sarkar. Prior to my Ph.D., I completed a Master’s degree in Computer Science at Rice University in 2017.
My PhD research is primarily centered around ensuring the correctness and enhancing the performance of accelerated applications. Most of my work is related to OpenMP and the LLVM compiler. I work closely with researchers from national laboratories and actively engage with the LLVM and OpenMP communities, while also collaborating with colleagues from various universities.
