DIMACS/CCICADA Interdisciplinary Seminar Series Presents
Title: Visual Analytics of Heterogeneous Data in Life Science Applications

Speaker: Hans-Jörg Schulz, University of Rostock, Germany and Graz University, Austria

Date: Monday, October 31, 2011 11:00am - 12:00pm

Location: DIMACS Center, CoRE Bldg, Room 431, Rutgers University                 
             Busch Campus, Piscataway, NJ


Data from real-world applications is often heterogeneous, exhibiting
sparse and non-uniform distributions across a huge, multi-dimensional
data space. Different subsets of heterogeneous data need to be treated
differently - queried differently, analyzed differently, shown
differently. This is an inherent problem for Visual Analytics already
identified in Thomas' & Cook's Visual Analytics research agenda in

Especially in the field of Life Sciences, where data are rarely
uniform with respect to their provenance, their type, or their
distribution, application experts are eager to finally get suitable
tools to handle these. This talk presents two of such tools, which
have been developed in close collaboration with medical experts:
VisBricks, which is a Visual Analytics approach that allows for an
intuitive, straightforward exploration of inhomogeneous tabular data,
and Stack'n'Flip, which is a visualization design for realizing Visual
Analytics workflows across multiple heterogeneous data sets. Based on
these two concrete examples, we establish a number of research
hypotheses regarding fundamental interrelations between inhomogeneity
and heterogeneity of data and its extension to other domains that
influence visual analysis.

About the speaker:

Hans-Jörg Schulz received his diploma (2004) and his PhD (2010) from
the University of Rostock, Germany. At present, he is a post-doctoral
researcher in a project on "Visual Support for the Analysis of
hierarchically structured, multiple heterogeneous Data Sources" at the
University of Rostock. Furthermore, he is associated with the graduate
school "dIEM oSiRiS" in Rostock and an associated researcher at Graz
University of Technology, Austria. His main interests concern the
visualization of graphs and the adoption of graph visualization and
analysis principles for non-graph structured data.
