BIOGRAPHICAL NOTE:
Tatiana von Landesberger is the Head of Visual Search and Analysis Group at Technische Universität Darmstadt, Germany. She obtained a Ph.D. degree in Computer science at this university in 2010. After finishing her studies of financial mathematics in Bratislava, Slovakia in 2003, she worked for the European Central Bank. Since 2006, she conducts research in visual analytics and in the area of information retrieval. Her main research interests are visual analytics of complex data and visual exploration of large data sets (networks, spatio-temporal data, multivariate data, etc.) in various application areas incl. biology, transportation or finance.
DETAILS OF RESEARCH:
The research goals are to develop new visual-interactive techniques for data search and exploration and for data analysis in various areas. One research strain deals with visual analysis of networks from various application areas, such as social science, finance, biology, transportation, or software engineering. The new techniques support different analytical tasks such as understanding of the graph structure (social networks extracted from news articles), examination of network dynamics (traffic analysis), analysing dynamic processes on networks (e.g. financial contagion, molecular evolution), or comparison of graphs (e.g., comparison of phylogenetic trees). Another part of the research is the research of new visual analytics tools for the analysis of geolocated data such as person movements in evacuation, flows of people in a city (based on twitter or mobile phone usage locations), or group movements of animals. We research new visualization techniques for data search such as new modalities for query definition and visualization of research results for multivariate and time series datasets (e.g., natural science observations). Recent project presented new visual analytical methods for the evaluation of medical image segmentation results, especially comparison of segmentation algorithms.
