# University of Waterloo

I am currently working at the University of Waterloo, and therefore I cannot be reached at the TU Berlin, except by eMail.

## Research interests

In general, I am interested in combinatorial optimization, graph algorithms, complexity theory and approximation algorithms. In particular, my current research is focused on **network flows over time**, which are also called **dynamic flows**.

Part of my research explores the combination of network flows over time with other combinatorial optimization problems:

Orientations | Scheduling |

I'm also interested in applications, which for my research usually come from the areas of:

Logistics | Telecommunication |

Evacuations | Petroleum Gas Transport |

## Projects

Efficient Network Flow Methods for Instationary Gas Flows |
---|

2014 – |

Natural gas is an important source of power and a significant amount of natural gas is transported by pipelines. From a mathematical optimization perspective, this pipeline system is not well understood. This project focusses on developing techniques based on network flows for natural gas pipelines. |

Applications of Network Flows in Evacuation Planning |
---|

2009 – 2014 |

Buildings and cities become continuously larger, causing evacuations of endangered buildings or areas to become increasingly difficult to handle. This project focuses on developing the theory of network flows over time (or dynamic flows) to meet the challenges posed by real-life evacuation problems. |

An Open-Source Toolkit for Evacuation Modelling |
---|

2007 – 2014 |

A tool to model and simulate evacuation situations in buildings using flows on graphs and cellular automatons. It allows visualization of both models in OpenGL. |
