My name is Chen Liu. Welcome to my homepage!

I am currently an assistant professor in the Department of Computer Science, City University of Hong Kong. I am the PI of Machine Learning and Optimization (MLO) group. I am interested in building reliable machine learning models. Particularly, I focus on deep neural networks and study it from an optimization perspective. I am a co-organizer of Deep Learning and Optimization Seminar.

If you are interested in working with me, please check the page of openings and feel free to email me with your CV.

I obtained my Ph.D. degree from École Polytechnique Fédérale de Lausanne (EPFL) in August 2022 and was supervised by Prof. Sabine Süsstrunk and Dr. Mathieu Salzmann. My Ph.D. thesis is about verifiable, generalizable and efficient robust deep neural networks. I obtained my Master degree from École Polytechnique Fédérale de Lausanne (EPFL) in 2017 and Bachelor degree from Tsinghua University in 2015, both in Computer Science.

I was supported by Microsoft Research Ph.D. Scholarship Programme from 2017 to 2019, working with Dr. Ryota Tomioka from Microsoft Research Cambridge. I worked at Swisscom Digital Lab in Lausanne, Switzerland in 2017 and Siemens Healthineers in Princeton, New Jersey, USA in 2016.
