Ka-Ho Chow

The University of Hong Kong (HKU)

I am an Assistant Professor in the Department of Computer Science at the University of Hong Kong (HKU). I was named an IBM PhD Fellow in 2022 and a Croucher Scholar in 2021. Before joining HKU, I was a research scientist at IBM Research and received my Ph.D. in Computer Science from the Georgia Institute of Technology (Georgia Tech), advised by Prof. Ling Liu.

My research interests are at the intersection of machine learning, cybersecurity, and systems. The overarching goal is to amplify the real-world impact of artificial intelligence by building trustworthy and scalable technologies. To this end, my recent work focuses on (i) understanding new security and privacy threats to AI systems, (ii) developing attack-resilient solutions, and (iii) enhancing scalability through algorithmic and infrastructure optimization. These efforts span various learning approaches, including centralized and federated learning, and cover a range of applications across, e.g., large language models and visual recognition.

Recruitment: I have several openings for Ph.D. students, research assistants, and interns. If you are interested in machine learning, cybersecurity, and systems, please reach out to me via email: kachow@cs.hku.hk
