About Me


I am a 3rd year PhD student in computer science at University of California Davis, advised by Hamed Pirsiavash. Before this, I got my BS in computer science from Sharif University of Technology. Get my CV. My research is about machine learning, computer vision. In particular, I am intrested in self-supervised learning, multimodal models (e.g., language and vision) and efficient AI models in edge devices.
