Welcome

I am an Assistant Professor in the Department of Computer Science, Luddy School of Informatics, Computing, and Engineering, Indiana University Bloomington (official faculty profile). Previously, I was an assistant professor at the University of Hawaiʻi at Mānoa (Electrical & Computer Engineering and Information and Computer Sciences). I received my Ph.D. in Computer Science & Engineering at Michigan State University, US, in 2024, an M.S. in Computer Science from Ball State University (fully funded with Research Assistant Scholarship), US, in 2019, and a B.S. in Communications Engineering from Chongqing University of Posts and Telecommunications, China, in 2015. Prior to academia, I was a research scientist at Samsung Research America (Knox security team) and Amazon (ML security team, San Diego).

My research focuses on trustworthy AI and wireless sensing security. Recently, I am especially interested in speech watermarking, music watermarking, copyright protection, mobile sensing, and ultrasound sensing for security. I study vulnerabilities in real-world AI and sensing systems and design practical defenses.

Opening: I am actively seeking highly motivated Ph.D. students and research interns at IU Bloomington. If you are interested, please email me your CV, transcripts, and a brief description of your research interests.
