About me bio
I am a Postdoctoral Research Associate in Computer Science at Brown University working with Seny Kamara. I received a French-American joint Ph.D. degree from IMT Atlantique and Colorado State University. My main research area is applied cryptography and, especially, its intersection with algorithms and data structures. My research focuses on designing provably-secure protocols that are efficient and ready for real-world deployment. Inspired by real world problems, I enjoy working in the area of encrypted search and aim to provide a better understanding of the balance between security and efficiency. One of my best examples is Clusion! An open source library implementing advanced encrypted search schemes.
I am the associate director of the Encrypted Systems Lab and am a member of the CAPS research group. Here are my DBLP and Google Scholar links.
