Assistant Professor

Computer Science

Purdue University

My research interests focus on practical and applied cryptography, namely the design and analysis of real world cryptographic systems. I aim to make it easier to design and securely deploy new and complex cryptographic systems while preventing insecurities from occurring in such systems. While this currently involves a large amount of manual work, my goal is to instrument many of these processes through the use of cryptographic automation, including automating the discovery of cryptographic vulnerabilities and building tools to aid in the deployment of complex cryptography.

I run the BARC (Boilermakers' Applied Research in Cryptography) Lab at Purdue. I am fortunate to be able to work with many great students on this research!

See my CV for more information.

I am currently looking for Ph.D. students and other talented, highly motivated students to join my research group.

If you are a prospective Ph.D. student, please make sure to apply and put my name on the application! If you are already at Purdue and are interested in working with me, please send me an email and fill out this form so that I can get to know you! I also highly recommend that you take my CS 590 class on Practical and Applied Cryptography in Spring 2021.
