Josef Widder


I am temporary associate professor (Privatdozent) in the Embedded Computing Systems group at TU Wien.
In the past, I worked at the Parasol Lab at Texas A&M University, the Laboratoire d’Informatique LIX at Ecole polytechnique, and at the FORSYTE group at TU Wien.

My primary area of interest is the theoretical approach to distributed algorithms, currently focussing on automated verification of fault-tolerant distributed algorithms.

CV from January 2017.

CfP: Workshop on Exploiting Concurrency Efficiently and Correctly (EC^2 2010)

The annual Workshop on Exploiting Concurrency Efficiently and Correctly (EC2) is a forum that brings together researchers working on formal methods for concurrency, and those working on advanced parallel applications. Its goal is to stimulate incubation of ideas leading to future concurrent system design an verification tools that are essential in the multi-core era.
