About me
I am the Daniel P. Siewiorek Assistant Professor of Human-Computer Interaction at Carnegie Mellon University. I received a B.S in Computer Science from Tsinghua University and an M.S. and a Ph.D. in Human-Computer Interaction from Carnegie Mellon University. I have received multiple NSF awards (CRII, Cyber Human System, EAGER on AI and Society, Fairness in AI, and Smart and Connected Communities), several paper awards in venues such as CHI, CSCW, and Human Factors, and an Allen Newell Award for Research Excellence.
Pronounce my first name: “High-ee”
About my research
I am a social computing researcher. My research interests lie at the intersection of human-computer interaction, machine learning, and social psychology. I have broad interests in the design and social impact of AI technologies in online and offline communities. I am particularly interested in developing novel methods for creating AI systems that respect and balance community stakeholders’ values.
