Arnd Hartmanns
I am an associate professor in the Formal Methods and Tools group at the University of Twente.
My primary research interests are modelling tools and formalisms for stochastic timed and hybrid systems (in particular Modest) and their applications in various fields.
I advocate reproducibility in Computer Science research, via artifact evaluation initiatives, tool competitions, and standardised benchmark sets.
I was previously a postdoc in the Formal Methods and Tools group at the University of Twente and the Dependable Systems and Software group at Saarland University, where I also completed my Ph.D. in computer science with a thesis On the Analysis of Stochastic Timed Systems in 2015.
