About Me
About Me
I am a highly motivated graduate with a strong interest in cybersecurity, particularly cryptography and theoretical computer science. I recently completed a Master’s degree in Cybersecurity at EPFL and ETHZ, where I specialized in theoretical and mathematically oriented courses. Before that, I earned my Bachelor’s degree from a University of Applied Sciences, where I focused on practical programming, systems, and project-based learning.
Research interests: witness encryption, interactive oracle proofs, lower bounds.
I am currently a PhD student in Computer Science at EPFL, supported by the EPFL Fellowship, and I am working on witness encryption under the supervision of Professor Serge Vaudenay.
Current Research
I collaborate with:
- Prof. Serge Vaudenay on witness encryption
- Dr. Jonathan Bootle and Prof. Alessandro Chiesa on proving the security of linear-time interactive oracle proofs
- Prof. Eylon Yogev on establishing lower bounds for digital signatures
