I am an independent Security and Privacy researcher.
My main research interest is the security and privacy of embedded systems and IoT devices. I presented my research at the Chaos Communication Congress, REcon BRX, HITCON, NULLCON, and DEFCON.
You might know me from my work at Northeastern University in the Khoury College of Computer Science, with Prof. Guevara Noubir as my advisor. I was the teamlead for the Northeastern University CTF team "NUSEC". I was a TA for CY 5770 "Software Vulnerabilities and Security" (Engin Kirda, Spring 2021), CY 4740 "Network security" (Guevara Noubir, Fall 2022), CS 3740 "Systems Security" (Spring 2023, Kaan Onarlioglu) and CY 5770 "Software Vulnerabilities and Security" (Summer 2023, Kaan Onarlioglu).
