Welcome!
I am conducting research in mathematical programming and operations research, on the edge between computer science, mathematics, and economics, and with a focus on computational methods and numerical implementations of high performance. My particular research interests include (but are not limited to):
 Discrete Algorithms & Combinatorial Optimization & Mathematical Programming & Operations Research
 Integer Programming, (Non)Linear Programming, in particular Binary (Quadratic) Programming
 Branch&Cut Algorithms, Reformulation and Linearization Techniques
 Efficient Algorithms & Data Structures, Algorithm Engineering and High Performance Computing
 Graph Algorithms, Drawing, and Theory
 Data and Network Analyses
 Numerical Optimization
A particular emphasis in my scientific work is on a better solution of
optimization problems in practice, e.g., by improving or reformulating
corresponding models, by sophisticated computational advances such as
engineered separation algorithms, by exploiting structures to derive
tailored preprocessing and solution methods, or by enhancing the respective
solution methods themselves.
Please find below a selection of current research projects
as well as publications.
Academic Background & Professional Appointments

Research Projects
Three major selected current projects are:

Inductive Linearization for (constrained) Binary Quadratic Problems (Theory and Computational Study)
 The novel solver (also available as a webbased service) McSparse for (sparse) Maximum Cut and Unconstrained Binary Quadratic Optimization (paper @ALENEX22)
 The relaunch (and stepwise enhancement) of a Spin Glass Server that was previously run at the University of Cologne.
Publications
You may access a full publication
list (i.e., with theses as well as recent and earlier preprints)
here.
A list of peerreviewed publications is also available via
ORCID.
Finally, you might also take a look at
DBLP, however,
as you see some of the rather mathoriented journal publications are either not
listed there or only listed with a quite large delay.
