I am a PhD student at Georgia Institute of Technology in the Systems Software & Security Lab advised by Taesoo Kim. My research interests are systems security and, in particular, mobile security and binary analysis. I have worked on ARM TrustZone security and native code of Android applications. If you are interested, send me an email, and I am happy to talk!

Before I started the PhD, I did a Master’s at FAU and an internship at the UCSB SecLab.

Personal Projects

Magic Mirror

In 2019 I did a hardware project inspired by Dylan Pierce’s MirrorMirror. I built the frame with my dad and wrote a simple flask app for the interface. You can find the source code on GitHub.


If I find time, I play Capture-The-Flags (CTFs). Some write-ups are available on my GitHub page (i.e., Tasteless CTF 2020, hxp CTF 2020, Google CTF 2020, Da Vinci CTF 2021).

Also, I was a challenge author and organizer of the FAUST CTF (CTFTime ranking 100/100 in 2021). With FAUST, I also qualified for the RuCTF Finals 2019 in Yekaterinburg, and we ranked first in the Cyber Security Rumble Germany 2020 (second in the international ranking).

High-Performance Computing

Before I focused on system security, I worked on high-performance computing. I participated in the Student Cluster Competition of the International Supercomputing Conference (ISC17) in 2017 with a team of fellow students from my local university. We ranked first in the category of the highest LINPACK and received the Highest LINPACK Performance Award.

PhD & Writing Resources

Recently, I started collecting resources that I found (and find) helpful for academic writing and on how to approach a PhD program. I listed them below, mainly as a reference for myself. Maybe you find some of them helpful as well.
