Liangcheng (LC) Yu

I am a rising 5th year Ph.D. student in the Department of Computer and Information Science at the University of Pennsylvania supervised by Prof. Vincent Liu. Before Penn, I sampled ~~random~~ experiences in various contexts of networked systems.

I am broadly interested in systems and networking, which attracts me with its nature of being tangible and inherently interdisciplinary (e.g., with areas including distributed systems, programming languages, and machine learning), and I am self-motivated to acquire new knowledge with a problem-driven mindset. I also have a personal interest of peeking into the domain from the control theory perspective. Recently, my primary interest has been in harnessing the latent opportunities in resource underutilization to support system functions in Terabit networks. This involves working with emerging artifacts, such as switching ASICs (including programmable, non-programmable, and INT-enabled ones), SmartNICs (encompassing DPUs, FPGA-based, NP-based variants), and high-speed interconnects.
