Jonghyun Choe
Hi, I am a Masters in Computer Science (MSCS) student at Carnegie Mellon University. I am interested in areas of large-scale systems, computer architecture, and hardware/software co-design. My goal is to optimize emerging workloads across the software, hardware stack to improve the efficiency of large-scale systems.
I lived abroad in United States and China for 10 years. I really enjoy learning new things and connecting with people, so please feel free to reach out for a talk!
