Josef Widder


I am external associate professor (Privatdozent) at TU Wien and senior research scientist at Informal Systems.
In the past, I worked at the Parasol Lab at Texas A&M University, at the Laboratoire d’Informatique LIX at Ecole polytechnique, at the ECS and FORSYTE groups at TU Wien, and at Interchain Foundation.

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





Past projects

  • PRAVDA. Parametrized Verification of Fault-tolerant Distributed Algorithms (FWF)
  • APALACHE. Abstraction-based parameterized TLA+ checker (WWTF)
  • RiSE. Rigorous Systems Engineering (FWF)
