Root Cause

     

My technical background involves software engineering in C/C++, vulnerability/exploit research, and exploit mitigation development that spans targets ranging from desktop applications such as web browsers, embedded game consoles, to mobile devices. My professional titles have included director, engineer, consultant, and founder. All technical topics fascinate me, from machine learning to cryptography to memory safety. I have a strong interest in the intersection of cyber security policy, technology, and US national security.

Professional Experience
I am currently a security engineer at a big tech company. I'm also a non-resident research fellow at the Georgetown Center For Security and Emerging Technologies (CSET).

I've been invited to give guest lectures at the US National Security Agency, the US Army, NYU Tandon School of Engineering, and Columbia University. I've published articles in IEEE ‘Security and Privacy’ magazine, and cfr.org. I've sat on the Black Hat content review board since 2012.
