Michael L. Bass

Professor of Environmental Science and  Biology

mbass@umw.edu
438 Jepson Science Center
Phone: (540) 654-1424

Ph.D. – Virginia Polytechnic Institute and State University

Bass’ areas of interest include the study of the physiological effects of pollutants on aquatic invertebrates, especially the interaction of temperature and toxicity. He is also actively monitoring the macrobenthic and periphyton community structure in freshwater streams that are impacted by non-point source pollution. Additional research concerns the effectiveness of riparian forested buffers in preventing nutrient, sediment and pesticide loading from agriculture run-off in streams.

M.S., Ph.D. – University of Michigan – Ann Arbor

Hayob’s research interests include igneous and metamorphic petrology, mineralogy, and geochemistry (thermodynamics and phase equilibria). More specifically, she has conducted research on the metamorphism of rocks from the lower crust of central Mexico, the origin and development of microtextures in feldspar minerals, and the metamorphism of Piedmont rocks near Fredericksburg.

Hayob has also conducted high temperature, high pressure experiments with the piston cylinder apparatus at the U.S.Geological Survey in Menlo Park, California. Much of her research has been collaborative with scientists from the U.S.G.S., University of Arizona, and University of South Florida. Most of Hayob’s field work has been done in Canada and Mexico, and more recently in the Appalachians of Virginia.

Associate Professor of Geology and Environmental Science

Phone: (540) 654-1107

Ph.D. – University of Arkansas

Kisila is interested in the behavior of contaminants and nutrients in the context of natural aquatic systems; using tools such as hydrochemical water analysis, transient and steady state tracers, particle fluxes and sedimentation rates, multivariate statistics and Geographic Information Systems (GIS). Of particular interest are analyses of surface water site-specific contaminant sources as well as broader contaminant issues associated with long-range atmospheric transport; eutrophication of lakes and reservoirs associated with fluxes of nutrients and increase of productivity in surface waters; watershed geomorphological analysis; use of geophysical methods in sedimentation research such as multifrequency echo-sounding systems to estimate sedimentation rates, sediment thicknesses and stratigraphical sequences in lakes and reservoirs; using isotopes in estimating sediment fluxes and sediment fingerprinting (natural versus anthropogenic); ground water quality and contamination; and the interaction between surface and ground waters, i.e., using major ions and stable isotopes in establishing mixing trends and contamination.

Present research focus includes the following:

1. Bathymetry, geology, sedimentation, and geochemistry of lakes and reservoirs

2. Watershed changes and analysis: impact on water quality in streams, lakes and reservoirs

3. The impacts of dam removals

4. Isotopic analysis of vegetation evolution as a function of both climatic change and human activities.

M.S. University of Pittsburgh

Morelli’s recent research has focused on the formation of breccias and their role in groundwater flow in the Oasis Valley Region of Southwestern Nevada.   Since groundwater in the Oasis Valley region flows from Pahute Mesa (where hundreds of underground nuclear bombs were detonated), it is important to understand how the local geology effects the flow of this (possibly contaminated) groundwater. Additionally, breccias related to faulting may provide an expressway, were water can flow quickly from one area to another. The large volume of  breccias mapped in Oasis Valley were formed during the Miocene when several intense, extensional “pulses” stretched the crust.  My research described and discussed the formation of these breccias, specifically if they were structurally related (directly produced by faulting) and if they could provide a fast-track pathway for the flow of groundwater.

Melanie SzulczewskiMelanie Szulczewski

Assistant Professor of Environmental Science

mszulcze@umw.edu
438 Jepson Science Center
Phone: (540) 654-2345

M.S., Ph.D. University of Wisconsin – Madison

Szulczewski (pronounced “Scholl-chess-ski”) has worked with contaminated and degraded soils in the mid-West, the Everglades and southern Florida, and the Sahel region of Africa. She is now pursuing similar issues in the Chesapeake Bay watershed. Szulczewski’s research interests include studying soils contaminated with heavy metals as well as environments degraded due to excessive nutrients (nitrogen or phosphorus) or desertification. With experience in international and local extension work, Szulczewski also investigates the effects of human behavior on the environment, both as a cause and potential solution. One current project encompassing the social aspect of remediating degraded environments involves the study of solar cooking adoption as a way to decelerate desertification and improve environmental quality in West Africa.

Neil TibertTibert1

Associate Professor of Geology

ntibert@umw.edu

Phone: (540) 654-1423

Ph. D., University of Massachusetts, Amherst

Tibert grew up on the shores of the Bay of Fundy where he developed a
first hand appreciation for coastal environmental processes. He is currently
involved in several resarch projects that include the taxonomy and palecology
of microfossils (ostracodes and foraminifera) that resided in the ancient
swamps, lagoons and estuaries of Paleozoic and Mesozoic North America.
His recent projects involve the application of microfossils to document
high-resolution environmental changes (both anthropogenic and natural)
in modern marsh and estuarine ecosystems of the Atlantic coast.

Ph.D. – University of Pittsburgh

The primary focus of Whipkey’s recent research has been the impacts of pollutants on natural water systems, including acid mine drainage and the sources of PCBs to lake water sediments.  He has also worked on the geochemistry and isotope geology of carbonate minerals and has carried out research on clastic sedimentary rocks in central Pennsylvania and in Paleocene and Eocene strata of the Powder River Basin of Wyoming and Montana. Prior to completing his Ph.D., Whipkey spent six years as a hydrogeologist with several environmental consulting firms, where work on military bases, chemical plants, and other facilities taught him a great deal about the practical as well as technical aspects of the field.

While still at Yale University Woodwell did postdoctoral research into the subject of nuclear waste disposal for the Oakridge National Laboratory in Tennessee. Woodwell’s research interests encompass structural geology and stable isotope geochemistry. Specific research has included studying the sources, composition and movement of fluids in the Earth’s crust, the effect of fluids on rock deformation and faulting, and understanding microscale deformation mechanisms and their associated rock fabrics. He has also been active in using computers to display spatial data and multidimensional geophysical data sets.
