Wele Gedara Chaminda Bandara
I am a Computer Vision Scientist (Engineer) at Apple, where I develop solutions to computer vision problems in the next generation of Apple devices.
I completed my Ph.D. in Electrical and Computer Engineering from Johns Hopkins University, advised by Prof. Vishal M. Patel. My dissertation research focused on spatiotemporal representation learning techniques for videos and remote sensing applications. Additionally, I worked on projects involving Generative AI, particularly with diffusion models, and low-level vision such as image segmentation and image super-resolution. During my Ph.D. studies, I had the opportunity to participate in two amazing summer internships at GetZippin in 2022 and Apple in 2023.
