Wolfram Decker

Prof. Wolfram Decker is a full professor of Mathematics at the Rheinland-Palatinate Institute of Technology Kaiserslautern (RPTU), where he has been since 2009. His primary affiliation is the Department of Mathematics. He holds a Diplom (1977), PhD (1984), and Habilitation (1989) from TU Kaiserslautern, and previously served as a professor at Saarland University (1990–2009). He has held leadership roles, including Dean of the Department of Mathematics (2014–2020) and deputy spokesperson of the SFB-TRR 195 research center.

Education: Studied Mathematics at TU Kaiserslautern (1971–1977), with early research roles at the same institution until his habilitation in 1989. His career includes professorships in Kaiserslautern and Saarbrücken, alongside coordinating major research initiatives like the DFG SPP 1489 (2010–2016).

Research focuses on computational algebra, algorithm design for algebraic geometry, and development of systems like SINGULAR and OSCAR. Key interests include Gröbner bases, modular techniques, and applications in theoretical physics (e.g., Feynman integrals). Recent work emphasizes parallel computing and large-scale algebraic algorithms.

Publications span computational algebra, with notable contributions to normalization algorithms, invariant theory, and Feynman integral reductions. His articles analyze both foundational methods and applied problems in algebraic geometry.

Advising: Supervised 13 PhD students, including Sorin Popescu (1993), Hirotachi Abo (2002), and Lukas Ristau (2019). Active in research teams like the SINGULAR and OSCAR development groups, emphasizing open-source software ecosystems.

Labs/Teams: Core member of the SINGULAR and OSCAR teams since 2009 and 2018, respectively. Work integrates algorithmic research with high-performance computing frameworks like GPI-Space.
