My research interests reside at the intersection of human-computer interaction (HCI) and responsible artificial intelligence (AI). More concretely, I am interested in understanding laypeople’s perceptions of AI systems and their impacts on society. Through my research, I intend to examine how AI can rectify social injustices instead of perpetuating them.

I am now investigating how AI developers can shape the public perception of decision-making algorithms. I am interested in how some of the ideologies shaping AI research, e.g., that algorithms are value neutral, can form laypeople’s understanding of algorithms deployed in high-risk domains. I study how these ideas can be exploited by developers to escape deserved accountability and help justify unjust social outcomes caused by decision-making AI to the public.

During my BS and MS, I investigated people’s perceptions of moral and legal responsibility for algorithmic decision-making. My research focused on capturing whom people consider responsible when AI causes harm to embed laypeople’s opinions in normative research and policymaking to mitigate any potential conflicts between folk expectations and AI governance.

I am a PhD student at the Max Planck Institute for Security and Privacy (MPI-SP), where I am advised by Yixin Zou. I obtained my BS and MS from KAIST, where I worked with Meeyoung Cha.
