Yuyang Du
I am a Postdoctoral Fellow in the Department of Information Engineering at The Chinese University of Hong Kong (CUHK). In 2025, I received my Ph.D. degree in Information Engineering from the same institution, where I was supervised by Prof. Soung Chang Liew. In 2019, I received my bachelor's degree from the School of Electronics Engineering and Computer Science (EECS), Peking University (PKU), under the supervision of Prof. Yiming Lei.
Before my Ph.D., I was an engineer at Huawei 2012 Lab, where I worked on wireless signal processing algorithms for 5G modem power optimization on Kirin 9000, one of the most advanced flagship 5nm SoCs at the time. In 2024-2025, I was a visiting scholar at Harvard University, where I worked on LLM reasoning and efficient inference with Prof. Marinka Zitnik and Prof. Minlan Yu.
I develop intelligent mobile systems, with applications in industrial automation and smart healthcare. Communication and computation form the foundation of these systems. My recent work addresses two key challenges: 1) cost-effective generative AI for resource-constrained edge devices, and 2) reliable, low-latency communication for real-time mobile applications. My toolkit for building such systems includes efficient LLM serving, task-oriented communication, signal processing, network optimization, and robotics.
*Recent Itinerary:* Since August 2026, I have been a Visiting Postdoctoral Researcher in the Department of Electrical and Computer Engineering at UC San Diego (UCSD), working with Prof. Nuria Gonzalez-Prelcic. I am always open to research discussions and ideas. If you are around, feel free to reach out for a coffee chat!
*Openings!* I will join the Department of Electrical and Computer Engineering at The University of Hong Kong (HKU-ECE) as a Research Assistant Professor in 2027 Spring. Our team has multiple openings for postdocs, research assistants, and visiting students in the following directions: 1) AI-powered wireless networking, 2) cost-effective LLM serving at the edge, 3) generative semantic communication, and 4) SDR-driven URLLC systems. Interested candidates are encouraged to drop an email to yuydu[at]ie.cuhk.edu.hk with CVs. Prospective PhD/MPhil students interested in 2027 Spring or 2027 Fall admission are also welcome to get in touch, and further details will be announced in due course.

Beyond Research [Gallery Coming Soon]
Cycling: I am an avid cyclist with a passion for both competitive racing and long-distance adventures. I raced for CAPU Racing (now Team PKU) during my undergraduate years (2015-2019). Even with a busy academic schedule after graduation, I stick to my daily training and currently maintain a power-to-weight ratio of 3.25 w/kg (tested on Aug, 2026). In the summer of 2016, I completed an epic bike tour to Mohe, the northernmost point of China, setting off from the vast Hulunbuir Grasslands in Inner Mongolia and traversing the dense forests of the Greater Khingan Mountains.
Trekking: I enjoy wilderness hiking and connecting with nature. My journey has woven through the vast, high-altitude realms of Garzê, the pristine alpine wilderness of Ngawa, and the rugged extremes of the BingChaCha passage from Yunnan to Tibet. I consider myself an incredibly lucky guy favored by the mountains: I was fortunate enough to catch the cloudless views of Kawagarbo (along the Bingchacha route), Minya Konka (in Garzê), and Yaomei Peak (in Ngawa). All of these peaks are notoriously elusive, and witnessing even a single one of them is considered a true blessing in Tibetan culture!
Mountaineering: Starting from May 2026, I have become fascinated by high-altitude snow mountain climbing. I successfully summited Mt. Siguniang (Dafeng, 5025m) on June 29, and Mt. Gangshika (Peak 3, 5005m) shortly after on August 15. Currently, I am learning ice climbing and glacier travel techniques to prepare myself for higher altitudes.
Alpine Skiing: Winter sports are another major passion of mine. I have been skiing across various regions, leaving my tracks in Chongli (Spring 2023), Koktokay (Winter 2023), and Pats Peak in New Hampshire (Winter 2024).
