Matías Andrés Mendieta

I am a machine learning research engineer at Apple. Before joining Apple, I obtained my Ph.D. in Computer Science from the Center for Research in Computer Vision at the University of Central Florida, advised by Dr. Chen Chen.

My research interests broadly span machine learning, computer vision, and autonomous systems. Currently, I am working on generative AI and computer vision for video restoration and editing. My works have been selected as CVPR Best Paper Finalist (2022) and ICCV Oral Presentation (2023).
