My professional focus lies in cryptographic technologies (such as end-to-end encryption, secure data sharing and computation on data, and authentication) with strong provable security guarantees and applications to concrete real-world problems (such as Big Data, Cloud, and transition to post-quantum systems).
In 2015, I received my PhD (Dr. rer. nat.) in cryptography from the Karlsruhe Institute of Technology (KIT) in Germany under the supervision of Prof. Dennis Hofheinz and second doctoral thesis appraiser Prof. Eike Kiltz on scalable identity-based encryption, short digital signatures, and modular revocation schemes. Larger-scale teaching activities included Algorithms I (lab, SS 2015) and IT security (lab, SS 2013), encompassed by several smaller-scale seminars and labs on the topic of cryptography.
In 2010, I received my Diploma in computer science from the Technical University of Braunschweig in Germany with a major in cryptography and software engineering. From March to September 2008, I worked as a software-development intern for Siemens USA in Princeton, New Jersey.

Other activities: I was involved in the standardization process of ETSI STF 529 within ETSI TC CYBER (on Attribute-Based Encryption for access control and data privacy). Moreover, I am a member of the International Association for Cryptologic Research (IACR).
Blog post: Together with my colleagues Sebastian Ramacher and Daniel Slamanig, I wrote a series of blog posts on Puncturable Encryption for fine-grained forward security in public-key encryption. See here for Part I (Introduction and Motivation) and here for Part II (Techniques and State-of-the-Art), and here for Part III (Applications and Implementation).
