Hi, I am a Masters in Computer Science student at Carnegie Mellon University. I am currently working on ML compilers and kernels at CMU Catalyst Lab, under the guidance of Professor Tianqi Chen. I will be working on inference at NVIDIA TensorRT-LLM team this summer.

My interests lie in optimizing performance of large-scale machine learning systems, from perspectives of compiler, scheduling, and kernel design.

Feel free to reach out if you’d like to chat!
