About me

How to pronounce my first name: “High-ee

I am the Daniel P. Siewiorek Associate Professor of Human-Computer Interaction and the Director of HCI Undergraduate Programs at Carnegie Mellon University. I direct the Social AI group at CMU. I lead research projects in human-computer interaction and responsible AI, funded by multiple programs at the National Science Foundation, the National Institute of Mental Health, and various industry sponsors. I have received over ten paper awards at venues such as CHI, CSCW, Human Factors, and CHIWORK, along with the Allen Newell Award for Research Excellence.

About my research

I study Human-AI Interaction, Social Computing, and Responsible AI. My research focuses on the integration of AI technologies and algorithms into various aspects of social groups, communities, and societies to improve, automate, or optimize social processes, interactions, and decision-making. I explore how we can enhance the benefits of these technologies while reducing potential harms. I have conducted several projects that focus on studying the design and use of AI in real-world high-stakes domains such as child welfare, mental health, gig work, and online content moderation.
