About Me
My name is Joyce Gill and I am a senior at Grinnell College majoring in Computer Science with concentrations in Statistics/Data Science and Digital Studies. At Grinnell, I am currently working on a Senior Capstone Project on Human-AI Interaction.
I am also working at Carnegie Mellon University's Human-Computer Interaction Institute (HCII) through the NSF REU Program. I work in Professor Paulo Carvalho's Optimized Algorithms and Knowledge (OAK) Lab to investigate how Large Language Models (LLMs) can optimize mastery-based tests to create personalized learning experiences for computer science students.
Prior to joining CMU HCII, I worked at Columbia University through the Amazon Summer Research (SURE) Program. I worked with Professor Brian Smith's Computer-Enabled Abilities Lab to explore how augmented reality (AR) can be used to combat gentrification and preserve oral history in Harlem, New York.
My research interests lie at the intersection of human-AI interaction, social computing, learning sciences, hybrid intelligence, and human-AI collaboration. I am passionate about designing and developing human-centered AI systems that supports the way people communicate, learn, and collaborate, with the goal of shifting the narrative from automation to augmentation.
A little bit more about me: I was born and raised in Seoul, South Korea, and my family is from Omaha, Nebraska. In my free time, I enjoy hiking, traveling, going on very long walks, and spending time with my friends, family, and dog. Check out my 'Favorites' page for more!
