About

Since 2021, I am a PhD candidate at UNSW Sydney in the field of Computer Science with focus on privacy-enhancing technologies (PETs). As a scholarship recipient, I receive funding from the Cyber Security Cooperative Research Centre (CSCRC) of Australia. My PhD project deals with the privacy-preserving publication of trajectories. I am honoured to work under the supervision of Prof. Salil Kanhere and Dr. Surya Nepal. My interests lie in all kind of security & privacy related topics, in particular, in the protection of both personal and industrial data.

Before starting my PhD, I completed a master’s degree in Computer Science at RWTH Aachen with honours and an overall grade of 1.0 (best German grade). My master’s thesis, written at the  Chair of Communication and Distributed Systems (COMSYS) at RWTH Aachen, deals with the privacy-preserving exchange of process parameters considering a real-world use case from the domain of injection moulding. My master’s thesis was awarded the Vöcking Master Award and the FOLKS Award for the best Master’s thesis.

In 2017, I finished my bachelor’s degree with honours at RWTH Aachen with an overall grade of 1.1 (German Grading). In the corresponding bachelor’s thesis, I designed, implemented and evaluated a platform for the privacy-preserving and user-controlled exchange of private information. Afterwards, I undertook an exchange year at the University of Technology Sydney (UTS).

I have been member of the dean’s list (best 5% of CS students at RWTH Aachen) from 2014 until 2020. Moreover, I was sponsored by the German education fund (Bildungsfonds) for 3 years during my studies. In 2016, I was awarded the best seminar award by FOLKS for my seminar paper on Bloom Cookies.

I worked as a teaching assistant for multiple subjects, including operating systems & system software, computability & complexity and introduction to business informatics. During my exchange year, I was running a python course for UTS housing that I had to organise from scratch. In 2019, I worked as a research assistant for a project regarding service bootstrapping via Bitcoin at COMSYS, RWTH Aachen which led to the publication of the paper Utilizing Public Blockchains for the Sybil-Resistant Bootstrapping of Distributed Anonymity Services at ASIACCS ’20. Additionally, my master’s thesis represents the foundation for the paper Privacy-Preserving Production Process Parameter Exchange, which was published at ACSAC ’20. I also contributed to the LASER’20 publication Collaboration is not Evil: A Systematic Look at Security Research for Industrial Use, which uses my master’s thesis as one major case study.

Personally, my main interests aside of IT are fitness & nutrition. I have been training for over 10 years, with my current focus on competitive CrossFit and marathon running. Moreover, I dance salsa, and enjoy cooking and exploring the world with my partner. You may find my personal blog (in German) at downunder.erikbuchholz.de.
