Amber Yijia Zheng

I'm a Ph.D. student in Computer Science at Purdue University advised by Prof. Raymond A. Yeh. I received my B.Sc. in Data Science at Shanghai University of Finance and Economics, where I was working with Prof. Yixuan Qiu.

I've had pleasure to work with Chen Chen at Apple, David Wipf and Tong He at AWS AI Lab.

My research interests lie in generative models and their applications across diverse tasks. Currently, I am interested in leveraging language models for vision. My past works include model editing, model immunization, image restoration, and manifold learning. Please feel free to reach out via email!
