About PI

Qijia Shao is always looking for highly-motivated postdoctoral researcher, Ph.D. students, and visiting students. His research focuses on mobile computing, ubiquitous computing, and human-computer interaction. His work has been published in top conferences and journals in his field (e.g., MobiSys, IMWUT/UbiComp, MobiCom, NSDI, CHI) and has been recognized by MobiSys Best Paper Award (2024), MobiSys Best Demo Award (2024), MobiCom Best Demo Award (2023), UbiComp Best Teaser Award (2023), Hotmobile Best Demo Award (2020), and NSF Awesome Discoveries (2019). He was also named among IEEE Pervasive Computing Emerging Rockstars, ACM UbiComp Gaetano Borriello Award Finalist, ACM MobiSys Rising Stars, NSF Rising Stars in Cyber-Physical Systems. He has been the Associate Editor of the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT/UbiComp) since 2024 and served as the technical program committee member for top conferences in mobile computing, including ACM MobiSys, SenSys, and others. Qijia has previously worked at Philips Research, Snap Research, and Samsung Research, where several of his proposed algorithms are being deployed in real-world products.

Research Area

We are passionate about solving real-world challenges with societal impacts. Our recent research focuses on building practically deployable systems and generalizable AI algorithms, particularly on the collection and analysis of human data, including physical signals (e.g., movement, force, velocity) and physiological signals (e.g., electrocardiogram/ECG, electromyogram/EMG, brainwaves/EEG, body impedance.) These signals are crucial for understanding human states, as human states are primarily influenced by physiological signals and manifested through physical signals. By efficiently acquiring and interpreting these two types of signals, we can comprehensively understand human states and use this data to solve practical problems in various fields (including but not limited to healthcare, education, interaction, entertainment ), thereby improving the quality of life. Our research requires integrating various technologies (such as machine learning, signal processing, wireless communications, integrated circuits, edge computing, operating systems, 3D printing, etc.) to address issues in two main areas simultaneously:

• Hardware System Design: Building systems to capture the desired data while minimizing user awareness of the system’s presence (imperceptibility), thus ensuring a natural and comfortable user experience.
• Software Algorithm Implementation: Leveraging the (limited) collected data to design algorithms and machine learning models that are generalizable to new user polulation and enrionments while maintaining low computation overhead.

2. Have a strong self-drive, be eager, and be able to quickly learn new knowledge in various fields.
3. Relevant research experience in either AI or mobile computing, and demonstrable research capabilities (e.g., papers, projects, design competitions).
4. A degree in computer science, artificial intelligence, electrical engineering, electronic information/communications engineering, automation, industrial design, mathematics, physics, or a related field.
5. Have seriously considered and understood the process of pursuing a Ph.D. (Here is a good reference article by Prof. H. T. Kung) and still be interested in trying it.
6. Be reliable, responsible, and have good communication skills, willing to communicate and share.

My Support

I am very willing to support my students in all aspects of their development. I will offer:

• Resources: Ph.D. students will receive a full scholarship (18,000+ HKD/month, with exceptionally outstanding candidates recommended for Hong Kong PhD Fellowship Scheme/HKPFS, 27,000+ HKD/month) and ample research facilities and computational resources.
• Individual Attention and Guidance: We will meet at least once a week. I am very willing to spend time discussing with you, as this is a major reason I chose academia. You will have considerable freedom to formulate your own research ideas and implement them. I will help you every step of the way, ensuring you never lack guidance, especially in the early stages of joining our lab.
• Clear Expectations: Pursuing a Ph.D. and conducting research can be a confusing and lonely journey. Based on my personal experience and communications with other Ph.D. students, I believe clear expectations from a mentor are very helpful. I will strive to clarify my expectations to help you understand your situation better. I also support appropriate recreational activities and vacations, as it is sometimes necessary to take a breather and refresh yourself.
• Internships and Visiting Scholars: During my own Ph.D., I benefited greatly from research internships. I fully support you in undertaking internships related to your research direction and am willing to internally recommend various internship opportunities (in China, the USA, Japan, Korea) as needed. I have connections with many universities overseas (mainly in the USA). Depending on your willingness and opportunities, I will support you in visiting and exchanging.
• Travel: I encourage students to attend conferences. I will support you to present our works at conferences. This was one of my favorite parts of my own Ph.D., the “free travel.”
• Guidance in Writing, Speaking, and Other Skills: Pursuing a Ph.D. is not just about technical expertise. I will help you improve your writing, speaking, and other skills to help you become a researcher with excellent communication skills.
• Entrepreneurial Support: The unique entrepreneurial atmosphere and strong industrial chain resources at HKUST will also provide you with significant entrepreneurial support. Our research directions ultimately require creating prototypes and testing them in the real world, which is often the first step for many startups. Therefore, when good opportunities and appropriate conditions arise, I will also support you in leveraging our research for entrepreneurship.
