Chethan Parameshwara
I work as a researcher at Amazon, focusing on Multimodal Generative AI, with a specific emphasis on Diffusion Generative Models and 3D Computer Vision.
Before joining Amazon, I graduated with a Ph.D. in Neuroscience and Artificial Intelligence (NACS) from the University of Maryland, College Park (UMD),
where I developed neuroscience-inspired computer vision algorithms for autonomous vehicles.
