Prospective Students

I always look for working with highly motivated students, in terms of RA/TA/externship/internship/visiting students. Interested candidates are strongly encouraged to contact me by email, together with resume and transcripts.

Short Bio

Sijia Liu received the Ph.D. degree (with All-University Doctoral Prize) in Electrical and Computer Engineering from Syracuse University, NY, USA, in 2016. He was a Postdoctoral Research Fellow at the University of Michigan, Ann Arbor, in 2016-2017, and a Research Staff Member at the MIT-IBM Watson AI Lab in 2018-2020. His research interests include scalable and trustworthy AI, e.g., adversarial deep learning, optimization theory and methods, computer vision, and computational biology. He received the Best Student Paper Award at the 42nd IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP). His work has been published at top-tier ML/CV conferences such as NeurIPS, ICML, ICLR, CVPR, ICCV, ECCV, AISTATS, AAAI, and IJCAI.

Research Interests

My research spans the areas of machine learning (ML)/deep learning (DL), optimization, computer vision, security, signal processing and data science, with a focus on developing learning algorithms and theory, and robust and explainable artificial intelligence (AI). These research themes provide a solid foundation for reaching my long-term research objective: Making AI systems safe and scalable. As AI moves from the lab into the real world (e.g., autonomous vehicles), ensuring its safety becomes a paramount requirement prior to its deployment. Moreover, as datasets, ML/DL models, and learning tasks become increasingly complex, getting ML/DL to scale calls for new advances in learning algorithm design. Thus, robustness and scalability underscore my current and future research, and of course, these two goals are intertwined. More broadly, the study towards robust and scalable AI could make a significant impact on machine learning theories, and induce more promising applications in, e.g., automated ML, meta-learning, privacy and security, hardware design, and big data analysis. I intend to seek a new learning frontier when the current learning algorithms become infeasible, and formalize foundations of secure learning.
