Yuchen Yang

I am a fourth-year Ph.D. student in Department of Computer Science at Johns Hopkins University, where I'm honored to be advised by Dr. Yinzhi Cao. I'm also working closely with Dr. Neil Zhenqiang Gong from Duke University. Before that, I received my M.S. in Security Informatics at Johns Hopkins University and my B.E. in Software Engineer at Shandong University.

My research interests focus on security and privacy issues in artificial intelligence (AI) and machine learning (ML). Currently, I'm working on the safety issue of AI generative content, e.g., evaluating the robustness of text-to-image generative models in preventing harmful generation. I'm also working on making privacy-preserving ML more accurate, e.g., accurate federated learning and differential privacy.

    • More about me

    I'm glad to introduce my cat Go-Wha, pronunciation in Chinese means PUPPY since he acts like a puppy all the time. Funniest and happiest cat I'v ever seen! You will know it with one click :)

    What's more? How about a cheerleader (former), a kayak learner (recent), and a hotpot lover (forever)!
