Background
Hi, welcome to my personal page! I am a research scientist at Waabi, led by Professor Raquel Urtasun, working on the next generation of autonomous driving technology. Specifically, I work on AI-based traffic-model simulation to improve and validate the autonomy stack. Before this position, I completed my Ph.D in machine learning at Georgia Institute of Technology under the supervision of Professor Chris Rozell.
Thesis Research
My research applied geometric models to deep learning to generate new views of data to improve performance with limited labels. To achieve this, I would use techniques like sparse coding, manifold learning, and self-supervised learning. I am interested in building large foundation models with sparse intermediary layers (i.e., only a few elements of each activation non-zero) for interpretability, robustness, and compute efficiency. One approach I have developed uses variational inference to reach similar performance as unrolled optimization routines, like FISTA, with a single neural network forward pass.
