Plenary Speakers

The organizers are pleased to announce the Plenary Speakers for ISSM 2014.

Peter Girguis, Ph.D.
Peter Girguis
Professor of Natural Sciences, Harvard University
"Hot-wired: The Nature and Extent of Extracellular Electron Transfer in Hydrothermal and Hydrocarbon Systems"
Peter Girguis is currently a Professor of Natural Sciences at Harvard University and studies microbes that grow in "extreme environments," concentrating on their role in mediating global biogeochemical cycles. Girguis is also chair of the National Science Foundation's Deep Submergence Science Committee, which advises the U.S. National Deep Submergence Facility. He received a B.S. from the University of California, Los Angeles, and a Ph.D. from the University of California, Santa Barbara.
Terry Hazen, Ph.D.
Terry Hazen
Governor's Chair Professor, University of Tennessee and Oak Ridge National Laboratory
"Microbial Community Structure Predicts Groundwater Geochemistry"
Terry Hazen is the Governor's Chair and Professor at the University of Tennessee. He is also a Faculty Fellow in the Biosciences Division of the Oak Ridge National Laboratory. He currently studies Systems Biology approaches to research in the Tropics related to bioenergy, U.S. Department of Energy (DOE) legacy sites, fracking, and deep sea oil biodegradation. He has also been involved in NASA projects that found a single organism ecosystem at 8,000 feet in South Africa and various U.S. DOE bioremediation demonstrations and field studies, resulting in five patents. Hazen assisted in organizing the first ISSM meeting in Orlando, Florida, in 1990. He received both a B.S and M.S. in Interdepartmental Biology from Michigan State University and a Ph.D. in Parasitology-Ecology from Wake Forest University.
Rainer Meckenstock, Ph.D.
Rainer Meckenstock
Chair for Aquatic Microbiology, University Duisburg-Essen, Germany
"Microbial Life in Oil"
Rainer Meckenstock was recently appointed as the Chair for Aquatic Microbiology at the University of Duisburg-Essen, Germany. Previously, he was a professor at the Technical University of Munich for 7 years and simultaneously served as the Head of Institute for Groundwater Ecology at Helmholtz Zentrum München for 11 years. Rainer's research interests include anaerobic degradation of aromatic hydrocarbons in contaminated aquifers. Recently, his research group discovered microbial life in oil as a new and extreme habitat on earth. Rainer was the Local Organizing Chair for the 2011 ISSM conference in Germany.

His research focuses on element cycling and biology of microorganisms at oxic-anoxic interfaces. Nielsen's previous research includes studying marine diversity, freshwater, soil, subsurface, and biotech environments, where he often used microsensors and stable isotopes to determine rates and controls of nitrogen cycle processes. With the help from a European Research Council Advanced Grant and other national funds, his research group is now following up on his discovery of microbial electrical shortcuts between oxic and anoxic environments.

Previously, he had a position as professor of Microbiology at University of Gothenburg, Sweden. He is also the CEO at Microbial Analytics Sweden AB, a professional research analysis and knowledge company that performs investigations, research, and training in technical and environmental topics on microbial processes. Pedersen has been researching microbial ecosystems that dwell underground in deep Scandinavian bedrock aquifers since 1987. He has published over 100 papers, book chapters, and reports for national and international research agencies. From 1998-2001, he was the Chairman for the European Science Foundation Scientific program on groundwater pollution and has been on the editorial board for several journals. Pedersen received a Ph.D. at the University of Gothenburg, Sweden, with a thesis on microbial biofilms in seawater.
Timothy Scheibe, Ph.D.
Timothy Scheibe
Staff Scientist, Pacific Northwest National Laboratory
"Scale Challenges in Utilization of Microbial Metabolic Network Models in Application-Scale Simulations"
Timothy Scheibe is a Staff Scientist at Pacific Northwest National Laboratory (PNNL). His research includes the characterization and modeling of multi-scale heterogeneity and its impacts on reactive transport in groundwater systems. As Co-Principal Investigator, he currently works on a research project that addresses issues in subsurface biogeochemistry, including microbial transport in groundwater, bioremediation of metals and radionuclides, and microbial carbon cycling in soils. Scheibe is also currently the Interim Associate Director of the Environmental Molecular Sciences Laboratory and leads the Molecular Sciences Computing division, where he manages the high-performance computing facility. He received a B.S. in Geological Engineering from Washington State University, and an M.S. and Ph.D. in Civil Engineering from University of Washington and Stanford University, respectively.
Jack Schijven, Ph.D.
Jack Schijven
Senior Scientist, National Institute of Public Health and the Environment (RIVM)
"QMRAcatch — A User-Friendly Computational Tool for Microbial Quality Simulations of Fresh Water Including Risk Assessment"
Jack Schijven works as a senior scientist at the National Institute of Public Health and the Environment (RIVM) in Bilthoven, The Netherlands. He is also the Chair for Quantitative Microbial Water Safety at the Faculty of Geosciences of Utrecht University. His research interests include modeling the transport and fate of microorganisms via surface water and groundwater in combination with quantitative microbial risk assessment. Schijven received a Ph.D. from Delft University of Technology, The Netherlands, with a thesis on virus removal by soil passage.
