About Me       My Lab       My Research       My Teaching       Misc

I am an Assistant Professor in the Edward S. Rogers Sr. Department of Electrical & Computer Engineering, University of Toronto, Canada. I direct the X-lab, which is a diverse team of people who build integrated circuits (IC) and systems that aim to improve the lives of millions, if not billions, of people. I am an affiliated scientist at the University Health Network, KITE Resesrch Institute. I am also affiliated with the Centre for Analytics and Artificial Intelligence Engineering (CARTE) and the Center for Advancing Neurotechnological Innovation to Application (CRANIA). I obtained my Ph.D. degree under the supervision of Prof. Jan Van der Spiegel at the University of Pennsylvania, USA. Before joining the University of Toronto, I spent five years working at Qualcomm Inc., USA.

My research expertise includes analog and mixed-signal IC design, vertical system integration, and edge artificial intelligence (AI). My current research develops ICs and systems for advancing brain health, digital communication, and machine learning acceleration [see my publications]. My industrial experience includes contributions to a series of top-tier IC products including the world's first commercial 5G chipset. I have received the IEEE Solid-State Circuit Society (SSCS) 2016 Predoctoral Achievement Award. My first author papers have received 3 Best Papers Awards on top conferences. I was also the recipient of the Student-Research Preview Award of the 2014 IEEE International Solid-State Circuits Conference (ISSCC).

*** (New) I have 3-4 openings for PhD students with full scholarship joining in 2024. *** If you are interested in my research or joining my team, please do not hesitate to contact me at xilinliu@ece.utoronto.ca. For prospective students and research fellows, please check our openings.

Research Overview

My current research focuses on developing integrated circuits (ICs) and systems for advancing human health, wireless and wireline communication, and edge machine learning. I conduct interdisciplinary research on the following three themes:

Theme 1: Electronics for Neural Interfacing and Neuromodulation

Theme 2: High-performance Data Converters for Wireless and Wireline Communication

Theme 3: IC Design for Accelerating Edge Machine Learning

Currently, I conduct research at the University of Toronto in collaboration with multiple faculty members in the Faculty of Applied Science & Engineering and the University Health Network (UHN), industrial partners, and researchers around the world.
