About Me

I’m a fourth-year ML PhD student at Georgia Tech, advised by Judy Hoffman. I’m interested in modular learning as a paradigm for training and composing task-specific modules into unified multi-task systems. My research focuses on understanding and controlling the behavior of deep neural networks, with a recent emphasis on training, aligning and merging fine-tuned models to improve multi-task performance and generalization

I earned my master’s in ECE in 2022 also at Georgia Tech, advised by Rishikesan Kamaleswaran, where I worked on machine translation on clinical sensor data as a research assistant.

I’m honored to be a recipient of the Herbert P. Haley Fellowship, Georgia Tech 2023-2024.
