Cheng Tan

I am an assistant professor of Khoury College of Computer Sciences at Northeastern University.

I’m broadly interested in computer systems. I build systems that enable users to verify their outsourced services. In particular, my recent research includes:

• verifying the execution of applications on untrusted servers,
• verifying behaviors of black-box databases,
• verifying neural networks for systems.

If you are interested in building systems, we should talk [c.tan (at) northeastern.edu].

About me

Before joining Northeastern, I got my Ph.D. from Courant Institute NYU advised by Michael Walfish, and my M.S. and B.E. from Fudan University and Nanjing University, respectively.

I was a student at NYU Systems Group. Before that, I was at IPADS and advised by Binyu Zang and Haibo Chen, where I did research on mobile systems and system virtualization.

I’m part of TEEX. TEEX is a secure distributed computing platform which provides a Layer-2 solution based on blockchain.

I also worked with a group of enthusiastic and interesting guys in Italy who were working on a startup company WalletSaver. I helped build the first version of their mobile app on Android.
