Full-time faculty position (professor adjunto) in Algorithms and computability

I am an adjunct professor at the Departamento de Informática Teórica since 2006. I received a master's degree in computer science in 1997 from Eberhard-Karls-Universität in Tübingen and a PhD in computer science, summa cum laude, from Eberhard-Karls-Universität in Tübingen in 2003. My current interests are in exact, approximative and heuristic algorithms for combinatorial optimization problems. My official brazilian CV (Lattes) currículo has more details.

I am lecturing Logic for computer science, Combinatorial optimization, and Advanced algorithms.

Previous semesters (in portuguese)

I am interested in algorithms and complexity (in particular with applications in bioinformatics), mathematical programming, optimization algorithms, parameterized algorithms and heuristics. I have been working with clusters and parallel computing (with applications in bioinformatics) and simulation of physical systems.

Students interested in “iniciação científica”, undergraduate and master's thesis, etc. in algorithms and optimization, please contact me. Our group's page (in portuguese) has more information.
