Abstract:

Biological data is often structured in the form of complex networks. Visual data exploration methods help scientists to extract information out of the data and are therefore very useful for building sophisticated research tools. Based on the modeling of biological networks using graphs, this presentation discusses examples of the structural analysis of networks and their dynamic visualisation.

Network comparison, network patterns and centralities are useful methods in the analysis of biological networks. The comparison of networks across organisms has several applications in life science. We discuss visualisation algorithms and interaction methods to compare networks visually and to support the exploration of complex structures such as network-based phylogenetic trees. Patterns (motifs) in networks may represent building blocks of functional modules that carry out a relatively distinct function in biological networks. We present different frequency concepts for pattern recognition, and navigation techniques to explore the underlying structure of the network given by the patterns. The ranking of network elements (vertices and edges) using centralities is another network analysis method. We compare several centrality measures for biological networks and discuss how visualisation enables better understanding of the data.

About Dr. Falk Schreiber:

Falk Schreiber graduated (1997) and obtained a PhD in Computer Science (2001) from the University of Passau (Germany). After this he worked as a Research Fellow and Lecturer at the University of Sydney (Australia). Since 2003 he is head of a research group at the Leibniz Institute of Plant Genetics and Crop Plant Research Gatersleben (Germany). His research is focused on the areas of algorithms, visualization, and bioinformatics; particularly in application-oriented and interdisciplinary directions.
