I am currently a DPhil student in Cyber Security at the University of Oxford, funded by the Clarendon Fund, the EPSRC, Kellogg College, and the CDT in Cyber Security. My research is on "Adversarial Electromagnetic Interference", and is supervised by Prof. Kasper Rasmussen.

I hold an MPhil in Advanced Computer Science with Distinction from the University of Cambridge, where I was the Goulandris Scholar at Magdalene College. I was supervised by Dr. Eiko Yoneki, and my dissertation was titled "Distributed Massive Graph Triangulation".

Earlier, I graduated Summa Cum Laude from Princeton University, with an AB in Mathematics. My thesis titled "A Practical Variant of Cuckoo Hashing" was supervised by Prof. Robert Sedgewick.


Most recently, I interned in the Embedded Systems team at Microsoft Research, where I worked with Dr. Ken Eguro on a side-channel project on FPGAs.

I have also been an intern in the Product Abuse team at Dropbox, the Windows Security team at Microsoft, and the Data License team at Bloomberg.

I was also a Grader and Lab TA at Princeton for courses across all undergraduate levels, and will resume similar duties at Oxford this academic year.

My name, spelled Ηλίας Γιεχασκιέλ in Greek, is pronounced as ee-LEE-us ye-ha-SKEL.

I like participating in security Capture the Flag contests. I am captain and co-founder of the Oxford Computer Science CTF Team Ox002147, and also individually placed second in Tripwire VERT's 2015 Cyber Security Capture The Flag Contest.

In the past, I used to compete in mathematical olympiads, at the National, Balkan (1, 2), and International (1, 2) level.

I am an alumnus of Camp Rising Sun, and the Ross Mathematics Program, both as a student, and as a Junior Counselor.

I added support for Greek in Hacker's Keyboard.

I also like to think that I am a decent goalkeeper.
