I am currently a final year Ph.D. student at Stony Brook University, supervised by Dr. Ting Wang. Prior to transferring to Stony Brook in 2023, I was a Ph.D. candidate at Penn State. I earned my Bachelor’s degree from Tianjin University and my Master’s degree from Zhejiang University (supervised by Dr. Shouling Ji). My research interests encompass adversarial machine learning, large language models, and deepfake detection.
I am on the job market. Feel free to reach out if you are interested in my research or have relevant opportunities.
