Dr. Ilias Giechaskiel
I hold a DPhil in Cyber Security for my thesis, Leaky Hardware: Modeling and Exploiting Imperfections in Embedded Devices, from the University of Oxford, where I was funded by the Clarendon Fund, the EPSRC, Kellogg College, and the CDT in Cyber Security. I spent the first half of 2019 as a “Visiting Assistant in Research (VAR)” at the Computer Architecture and Security Lab of Yale University, with which I still collaborate as a Research Affiliate. In 2014, I received an MPhil in Advanced Computer Science with Distinction from the University of Cambridge, where I was the Goulandris Scholar at Magdalene College. A year earlier, I graduated Summa Cum Laude from Princeton University, with an AB in Mathematics and a Certificate in Applications of Computing. In 2009, I was the valedictorian of Anatolia College's IB Diploma Programme.
Work and Teaching Experience
I am currently a Hardware Research Engineer at Jump Trading, where I also spent the summers of 2017 and 2018. Earlier, I interned with the Embedded Systems team at Microsoft Research, the Product Abuse team at Dropbox, the Windows Security team at Microsoft, and the Data License team at Bloomberg. During my degree at Princeton, I was a Grader and Lab Teaching Assistant (TA) at the computer science department for courses across all undergraduate levels. I have had similar duties in the mathematics and computer science departments at Oxford, including being the TA for masters-level computer security courses.

During my PhD years, I participated in several security Capture-the-Flag (CTF) contests, placing second in Tripwire VERT's 2015 Cyber Security Capture The Flag Contest. I co-founded the Oxford Computer Science CTF Team Ox002147, of which I was captain until 2019. The team was ranked top 100/14,000+ teams globally in 2017, and placed first in in-person CTF competitions organized by Deloitte and BAE Systems. In high school, I competed in Mathematical Olympiads at the Greek National, Balkan (1, 2), and International (1, 2) level.
I occasionally dabble with Android development, having added support for Greek in Hacker's Keyboard, and having published a Tasker plugin allowing messages to be sent over Bluetooth serial. I also recently became a licensed amateur radio operator in the UK as M7ILI.
I designed my brother's
prefers-color-scheme media feature.
