About Me

Hi! I am a student at the University of Washington double majoring in Computer Science and Math. I also study history on the side. I currently work as a research assistant at the RAIVN Lab under Prof. Ali Farhadi and Prof. Ranjay Krishna. I work closely with Aditya Kusupati and Matt Wallingford.

My current research interests include:

• Understanding the internal behavior of vision and language models.
• Efficient model architectures.
• AI and social/natural sciences.
