I am currently a post-doctoral researcher in the Department of Computer Science at Purdue University, working under the expert guidance of Prof. Aniket Kate. In 2022, I obtained my Ph.D. in Computer Science from Shanghai Jiao Tong University, where I had the privilege of being co-advised by Prof. Dawu Gu and Prof. Shi-Feng Sun.

My research mainly focuses on applied cryptography, especially blockchain, secure computation and provable security. I am dedicated to designing efficient and secure cryptographic protocols that enhance collaboration while ensuring privacy protection. For more detailed information about my academic and research background, please refer to my CV and research statement.
