I am an ARNI Postdoc at Columbia University working with Dr. Liam Paninski and Dr. Blake Richards. I did my Ph.D. at Georgia Tech and was advised by Dr. Eva L. Dyer. My main areas of interest are Representation Learning, Generative AI, Data-Centric AI, and Computational Neuroscience. I am actively working on developing methods for self-supervised representation learning for time-series and graphs, and developing frameworks to build large-scale multimodal foundation models to advance scientific discovery.
Through the development of new approaches for analyzing and interpreting complex modalities, I aim to make an impact in our understanding of the brain, and biological intelligence, and to contribute new tools that facilitate new scientific discoveries. I am currently working on developing a large-scale multimodal foundation models for neuroscience with the goal of improving brain-computer interfaces, along with our understanding of the brain.
