Physical and natural sciences, instruments, biomedical and other scientific research generate large amounts of high-dimensional data. This not only creates the need for the analysis of the data and interpretation of results, but also the need for the development of tools and methods that can handle these data. Tools for the data analysis are used not only in the hypothesis generation or exploratory analysis stage (where we try to find patterns, outliers, and other meaningful domain-specific insights), but also when looking for answers for these hypotheses. Many techniques are graphical in nature, such as scatter plots and histograms, but many of them can only represent two variables at a time. We address these issues by creating novel neural network and visualization techniques utilizing high performance computing-enabled research environment.

Personal Bio:

Dr. Marjan Trutschl is an Associate Professor of Computer Science, co-Director of the Laboratory for Advanced Biomedical Informatics at LSU Shreveport (LSUS) and Director of the Biomedical Informatics Core at the Center for Molecular and Tumor Virology at the Louisiana State University Health Sciences Center in Shreveport (LSUHSC-S). He received his Sc.D. and M.S. in Computer Science from the University of Massachusetts Lowell (UML).

Prior to joining LSUS, Dr. Trutschl co-founded Anvil, Inc. and worked as a research assistant at the Institute for Visualization and Perception Research at UML. In 2002, he co-founded Laboratory for Advanced Biomedical Informatics at LSUS and was named its co-Director in 2007. In 2003, he became Adjunct Assistant Professor of Bioinformatics and Computational Biology at LSUHSC and was named Director of the Biomedical Informatics Core at the Center for Molecular and Tumor Virology at LSUHSC-S in 2008.

Dr. Trutschl has over a decade of software development and research experience. He has or still is participating in research funded by the Genetics Institute (now Wyeth), Millennium Pharmaceuticals, Pfizer, Spacetec IMC (now Logitech), Department of Defense, National Institutes of Health, and by the U.S. Air Force, just to name a few. His research activities focus on information and scientific data visualization, biomedical informatics, neural networks, data mining, knowledge discovery, as well as cluster and distributed computing.

Dr. Trutschl has published and presented research in the areas of information visualization and bioinformatics and has funded grants in biomedical research and the integration of technology into the educational curriculum. He actively participates in organization of international conferences and symposia and serves as a reviewer to numerous international conferences and journals with international circulation.
