Research Projects

My research works on the intersection of Social Psychology and Human-Computer Interaction. I apply novel methods and techniques to understand dyadic and group process, to examine cultural patterns, and to integrate theories of functions of emotion to social agents.


Nonverbal Synchrony as an Adaptation to Social Environments

Thinking about traveling to a foreign country, or talking to a person from another place, what would you do to express yourself clearly? How do people use nonverbal coordination to adapt socially in which language may not be able to serve its optimal function? To study this question, I created in lab a set of tasks that elicit emotions, and facilitate cooperation. Using automated facial and bodily analysis, I also implemented novel methods to measure nonverbal synchrony.

Heterogeneity of Long-history Migration in Emotion Expressivity

Let’s conduct a little thought experiment here: Imagine you, as well as people from many other countries, are settlers who just landed on a new continent. People are social creatures. How would people cooperate to start a new community?

Recent work on cultures of facial expressions suggest that people from historically heterogenous countries exhibit greater, and more recognizable facial expressivity than people from historically homogeneous countries. We propose that these cultural norms originate from ecological pressure to cooperate and establish rapport with people with little common ground (in the form of shared cultural norms) and little shared language.

To study that, I extend the models and procedures that I created in nonverbal synchrony research to people from different nations.



Designing Socially Adept Agents

Have you ever gotten mad at Siri/Google Home/Cortana/Alexa when they just don’t understand you? Have you been entertained by smart agents when they suddenly act smart and make jokes?

My current research involves how to apply theories of dyadic interaction and emotion on human-robot interaction. I’m interested in developing and synthesis computational models that develop from dyadic interaction to social agents.


Human-Robot Collaboration

Human-robot collaboration has been inevitably prevalent in today’s industry and even daily life. Inspiring by collaborative dynamics during human-animal teamwork, I’m interested in studying psychological outcomes of human-robot collaboration, with the goal of looking for the optimal balance between human and robot contribution.
