Portfolio
Inspired by my interdisciplinary coursework, I am drawn to research leveraging AI for positive change in the world. I aim to better understand technologies and how we interact with them to create AI systems that can support people through healthcare, policy, and overall in meaningful, human-centered ways.
Below is a collection of works that summarize my academic interests.
