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 "Leaky Hardware: Modeling and Exploiting Imperfections in Embedded Devices", 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 twice in the FPGA/Hardware group at Jump Trading, and the Embedded Systems team at Microsoft Research, where I worked with Dr. Ken Eguro on a covert/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 a Grader and Lab TA at Princeton for courses across all undergraduate levels, and have had similar duties at Oxford.

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. The team was ranked top 100/14,000+ teams in 2017, and also placed first in in-person CTF competitions organized by Deloitte and BAE Systems. I also individually placed second in Tripwire VERT's 2015 Cyber Security Capture The Flag Contest.
I also made and administer my brother's personal and weight training book websites and my sister's beauty salon site. The canonical URL for this website is https://ilias.giechaskiel.com, but it can also be accessed through the more memorable ilias.io.
I like to think that I am a decent goalkeeper.
