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 am actively mentoring students, leading collaborative projects with academic, government, and community partners, and contributing to cutting-edge research in human-computer interaction and responsible AI. I have been leading multiple research projects funded by various National Science Foundation (NSF) programs, including CRII, Cyber-Human Systems (now Human-Centered Computing), EAGER on AI and Society, Fairness in AI, and Smart and Connected Communities, as well as the NSF-NIH Smart Health program. I have received over 10 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 special education.
