Zizhao Mo

Ph.D. in Computer Science

Hi, my name is Zizhao Mo (莫梓钊). I received my Ph.D. degree in Computer Science from the University of Macau, where I was fortunate to be advised by Prof. Huanle Xu at Cloud and Distributed Systems Lab.

My research interests broadly revolve around machine learning systems (MLSys), focusing on scheduling, parallelization optimization, and resource management topics. I also have a specific interest in designing efficient systems over heterogeneous resources, including CPU-GPU and heterogeneous GPU platforms.

I am currently on the job market and seeking opportunities from both academia and industry. Please feel free to contact me!
