I am a senior researcher and lecturer (Akademische Rätin) at the Department of Computer Science of the University of Kaiserslautern, in the AG Softwaretechnik.

Previously, I was a postdoc at INRIA (Paris-Rocquencourt), the French National Institute for Computer Science and Control Science. During that time, I was in the REGAL team at LIP6 where I worked together with Marc Shapiro.

Before moving to Paris, I was a Ph.D. student with Peter Thiemann in the Arbeitsgruppe Programmiersprachen at the Institute for Computer Science(http://www.informatik.uni-freiburg.de) at the University of Freiburg, Germany.

At the beginning of my PhD studies, I was a scholar of the DFG research training group Embedded Microsystems.


I am always looking for enthusiastic and motivated students to work with. Contact me via email or stop by my office to talk about possible topics for projects, theses, internships and open positions!

I am interested semantics of concurrent and distributed programming, with a focus on (geo-)replication, synchronization, and programming language concepts.

In particular, my research targets programming models that make use of relaxed memory semantics, where updates to the shared state are visible only eventually to other processes. This enables optimistic execution of computations with minimal synchronization overhead while still being able to construct programs with provably correct behavior.

I am also working on topics related to the development of correct and highly scalable programs in concurrent and distributed systems, such as Software Transactional Memory (STM) and Convergent Replicated Datatypes (CRDTs).

Lectures and courses at TU Kaiserslautern

Courses I co-organized with Peter Thiemann at the University of Freiburg

Further I co-supervised several student projects, bachelor and master theses on topics in compiler construction, program analysis, and concurrent and distributed programming.

Deutsche Schülerakademie

After participating as a student in 1999 in Braunschweig, I had the pleasure of teaching summer school courses for the Deutsche SchülerAkademie, a non- rofit organization for early science education, which is funded by the Bundesministerium für Bildung und Forschung and the Stifterverband für die Deutsche Wissenschaft.
