Background and activities

Network Biology

During the last few years, network approaches have shown great promise as new tools to analyze and understand complex systems. In biology, network formulations of a system naturally appear in situations ranging from food webs in ecology to biochemical interactions in molecular biology. In particular in the cell, the variety of interactions between genes, proteins and metabolites are well captured by a complex network description. My research is focused on developing both general and specific methods to understand the principles behind the design and organization of biological systems. Most of the work is theoretical and computational in nature, but I am also involved in smaller experimental efforts.

For the sixth year in a row, NTNU is competing in the international Genetically Engineered Machine competition (iGEM) with a team! Our 2013 team was recently featured on the popular science TV show for NRK (Norwegian Public Broadcasting), Schrödingers Katt.
