About

I'm a graduate student at Cornell Tech, pursuing a dual Master's degree in Information Systems and Information Science. My research interests lie at the intersection of machine learning, digital twins, and urban informatics, with a focus on developing ethically-aware AI systems for smart city applications.

Under the guidance of Dr. Junfeng Jiao at the Urban Information Lab, I have worked on several projects that leverage advanced analytics and information technologies to optimize urban design and planning. These include the development of a real-time fire tracking map for the City of Austin, a blockchain-based food charity marketplace to alleviate food deserts, and a large language model for computational tasks.

At Cornell Tech, I am involved in research at the Urban Tech Hub, where I contribute to the development of NLP tools and the optimization of 311 call responses using machine learning. I also serve as a teaching assistant for the Break Through Tech AI initiative, which aims to increase diversity in technology fields through targeted education.

Bio

I graduated from The University of Texas at Austin two years early with a BS in Mathematics and certificates in Elements of Computing and Computational Science and Engineering. During my time at UT Austin, I worked as an undergraduate research assistant at the Good Systems initiative, focusing on the ethical design and societal impact of AI and machine learning.
