Tyler E. Frankeltyler-frankel-photo-2b

Assistant Professor of Environmental Science

438 Jepson Science Center

Ph.D. – University of Maryland

Dr. Frankel received his Ph.D. from the University of Maryland – College Park for his research on the impacts of environmental gestagens on the reproduction of the fathead minnow (Pimephales promelas). His general research interests involve the investigation of anthropogenic pollutants on aquatic wildlife, with a specific interest in examining the effects of environmentally relevant endocrine disrupting chemicals on the viability, reproduction, and behavior of both vertebrate and invertebrate species. He is a member of the Society of Toxicology and Chemistry, and has been published in Environmental Science and Technology, Environmental Toxicology and Chemistry, and General and Comparative Endocrinology. Techniques utilized in his research include acute and chronic toxicity assays, fecundity assays, oocyte and sperm quality assays, reproductive behavioral assays, and endogenous sex steroid hormone analyses.

Professor of Geology and Department Chair
441 Jepson Science Center
Phone: (540) 654-1425

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.

Courses: Introductory Geology, Evolution of the Earth, Mineralogy, Petrology



Ben Odhiambo KisilaElyse Clark

Associate Professor of Geology and Environmental Science
440 Jepson Science Center
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.

Courses: Introductory Geology, Evolution of the Earth, Environmental Soil Science, Fluvial Geomorphology

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 S

Associate Professor of Environmental Science
438 Jepson Science Center
Phone: (540) 654-2345

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


Szulczewski (pronounced “Scholl-chess-ski”) has investigated contaminated and degraded soils in the mid-West, the Everglades and southern Florida, and the Sahel region of Africa, Poland, and the Chesapeake Bay watershed.  Szulczewski’s research interests include studying soils and streams contaminated with heavy metals, as well as environments degraded due to excessive nutrients (nitrogen or phosphorus), desertification, and other forms of human interference. With experience in international and local extension work, Szulczewski also examines the effects of human behavior on the environment, both as  a cause and potential solution, through sustainability projects and initiatives.

Courses: Introduction to Environmental Science, First-year Seminar, Global Environmental Problems, Pollution Prevention Planning, Environmental Geochemistry, Environmental Regulations Compliance, Environmental Exploration


Charles E. Whipkey

Associate Professor of Environmental Science and Geology

Whipkey Contrary Creek
432 Jepson Science Center
Phone: (540) 654-1428

Ph.D. – University of Pittsburgh

Whipkey has worked on the geochemistry and isotope geology of carbonate minerals of Hawaii 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.  More recently, he has examined the impacts of pollutants on natural water systems, including acid mine drainage and the sources of PCBs to lake water sediments.  Energy technology and resources are another recent interest, and he has supervised several students in studies of the solar and wind resources in Virginia.  Prior to completing his Ph.D., Whipkey spent several 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.

M.Phil., Ph.D. – Yale University

Woodwell has engaged in field work in the Canadian and American Rocky Mountains, the Appalachians and the Spanish and French Pyrenees. Prior to his appointment at Mary Washington College, Woodwell was a researcher at London University studying hydrocarbon migration in northern Spain in cooperation with Hispanoil petroleum company. 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.

In Memoriam

Neil E. Tibert (1966 – 2015)Tibert1

Our colleague and good friend Neil Tibert passed away in 2015 after a brief illness.  Neil’s wit and intelligence provided a spark to our department and the entire UMW community.  Neil was truly one of a kind and irreplaceable.

A newly described Cretaceous fossil turtle was recently named Paiutemys tibert, by Walter Joyce, Tyler Lyson, and James Kirkland, “in recognition of the late Neil E. Tibert, who was instrumental in establishing the stratigraphy of mid-Cretaceous beds in the type locality of the new taxon.”  See the article at
