Current Work

As part of the project ForNe, I am currently working on optimization of gas networks.

More specifically, I deal with the following problems arising within ForNe:

Nomination validation, i.e., feasible configuration of gas networks
Generation of candidates for gas network extension
Topology planning for gas network extension, given a finite set of extension candidates

Furthermore, I'm involved in the development and administration of the web interface for the solver software Lamatto++, based on CherryPy.

In addition, I help administrate the SLURM cluster queue for the Optimization department.
