Coder • Researcher • Math-Enthusiast • Artist


Hello! I am a Ph.D. student in the Machine Learning Department at Carnegie Mellon University. I research how machine learning and generative AI can support idea generation and intrinsic motivation for engaging with wicked, future-facing problems in project-based learning, design, and entrepreneurship. I am advised by Dr. Nikolas Martelaro (Human Computer Interaction) and Dr. Tom Mitchell (Machine Learning Department).

While at Carnegie Mellon University, I won the Tools Competition 2024 Award Catalyst Award ($50k) for my proposal "Artificial Mentors for Student-Driven Projects", and have since been researching how people select, elaborate, and iterate on their project proposals. In SP2025-FA2025 I worked with Dr. Peter Scupelli's design courses to understand barriers for high quality reflection and task engagement in future-facing sustainable and societal design.

Previously, I have worked on AI safety and large language models projects through internships at Microsoft Research (advised by Dr. Adam Kalai & Dr. Rosa Arriaga), Indico Data (advised by Madison May), and The MITRE Corporation (advised by Dr. John Henderson).

I finished my undergraduate at Olin College of Engineering majoring in Engineering: Computing. There, I worked as a computing researcher in Olin's Microbiology and Bioinformatics lab advised by Dr. Jean Huang, in Olin's Satellite + Spectrum Technology & Policy group advised by Dr. Whitney Lohmeyer, and on a senior capstone research project advised by Fidelity Center for Applied Technology.
