Xiaojuan Ma

I am an assistant professor of Human-Computer Interaction (HCI) at the Department of Computer Science and Engineering (CSE), Hong Kong University of Science and Technology (HKUST).

I received my Ph.D. in Computer Science at Princeton University. My Advisor was Prof. Perry Cook. I was a post-doctoral researcher at the Human-Computer Interaction Institute (HCII) of Carnegie Mellon University (CMU) with Prof. Jodi Forlizzi, and before that a research fellow with Prof. Zhenhui (Jack) Jiang in the National University of Singapore (NUS) in the Information Systems department. Before joining HKUST, I was a researcher of Human-Computer Interaction at Noah's Ark Lab, Huawei Tech. Investment Co., Ltd. in Hong Kong.

The HCI group @ HKUST designs and creates novel technologies, methods, and theories in the area of Human-Computer Interaction and Affective Computing. We welcome graduate students, post-docs, and visiting interns/scholars. Please send me your CV if your are interested in this topic or have any question.

My research interest is data-driven approaches to Human-Engaged Computing (Read more). We explore how to promote human's attentional, emotional, cognitive, and behavioral engagement when interacting with computing systems:

(i) Inference: sensing and modeling human engagement dynamicity
(a) Social signals
(b) Physiological signals
(c) Behavioral signals
(ii) Analytics: mining engaging factors from online and offline activities in everyday life
(a) Engagement with physical and virtual entities
(b) Engagement with social actors and collective activities
(iii) Application I with AI systems: machine intelligence for more engaging human-robot/agent interactions
(a) Emotionally and socially intelligent AI
(b) Engaging multi-party Human-AI collaboration
(iv) Application II with non-AI entities: hybrid realities for more engaging human-data/object interactions
(a) Informatics
(b) Narratives and communication
(c) Persuasion and recommendation
