Personal Information

• 1999 – 2005: Student of Computer Science at the University of Applied Sciences in Leipzig, Germany
• January 2005: M.Sc. in Computer Science
• October 2005 - September 2010: PhD Student at the University of Kaiserslautern, Germany
• Title of my PhD thesis: Optimization Problems in Self-Organizing Networks

In 2011 I joined the Network Planning and Optimization team at Detecon Dresden.

Topics of Research

I am interested in optimization problems in self-organizing networks. The following problems are related to topology optimization in various kinds of networks.

• Superpeer enhanced networks: A hub location problem
• Minimum Routing Cost Spanning Tree Problem: An efficient overlay topology for P2P networks
• Minimum Energy Broadcast: An NP-hard optimization problem in wireless networks
• Range Assignment Problems: Other NP-hard optimization problems in wireless networks
