Mengqian Zhang
I am currently a Postdoctoral Fellow in the Computer Science Department at Carnegie Mellon University, fortunate to be advised by Prof. Elaine Shi. I am also a member of Secure Blockchain Initiative (SBI) by CyLab.
Prior to this, I was a Postdoctoral Associate in the Department of Computer Science at Yale University, hosted by Prof. Fan Zhang, and a Postdoctoral Researcher at the Stern School of Business of New York University, hosted by Prof. Xi Chen and Prof. Elynn Chen. I received my Ph.D. in Computer Science from Shanghai Jiao Tong University, fortunately advised by Prof. Xiaotie Deng, and I was visiting the Center on Frontiers of Computing Studies, Peking University from July 2019 to December 2022.
My research interests mainly include blockchain, algorithmic game theory, decentralized finance, and FinTech.
