I am a researcher at COMSYS since 2015 and my main research interests are blockchain technology and the design of privacy-enhancing systems.

Blockchain technology, as introduced by Bitcoin, constitutes a virtually unchangeable log of events, e.g. financial transactions, and thereby eliminates attacks such as equivocation. In my research, I am interested in general properties of blockchains as well as their applications, e.g., to improve the trustworthiness of existing systems  and to discover entirely novel use cases.

Privacy-enhancing technologies (PETs) usually comprise basic principles and technologies that can be utilized to increase user privacy. With respect to privacy-enhancing systems, I am interested in developing new architectures that allow to utilize PETs in novel ways and thereby further reduce the trust users are required to put into the online services they use.

I was awarded the 3rd prize of Univention Graduate Award 2016 for my M.Sc. thesis about improving CoinParty, our mixnet-based approach to Bitcoin anonymization, and 3rd prize of MINT Award 2013 for my B.Sc. thesis about user-controlled utilization of sensor data in the cloud.
