M.S. – University of Colorado
Dr. Grothe, who obtained her B.S. in geology at UMW, has a Master’s in geology from the University of Colorado at Boulder and a Ph.D. in Earth and Atmospheric Sciences from the Georgia Institute of Technology, with a minor in higher education. Her research focuses on using the geochemistry from carbonate proxies, such as corals and mollusk shells, to reconstruct the climate over the last several hundred to thousands of years. One of her main research interests is understanding past variability of the El Nino-Southern Oscillation from the mid-Holocene using fossil corals from the central tropical Pacific. Her goal is to understand how ENSO is sensitive to external forcings, such as solar insolation, with possible implications to the greenhouse gas forcing. More locally, she is researching changes in rainfall patterns in the Chesapeake Bay region to better understand how the present-day rainfall patterns are related to natural variability versus human-induced climate change.

Dr. Kisila’s website: soilwaterresearch.weebly.com/
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.

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.

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.

Dr. Wessel is interested in the properties of saturated environments ranging from aquifers to marine sediments. He studies how they change through time, and how human actions alter them. He has mapped sediments and soils in several Chesapeake Bay subestuaries, collecting and characterizing core samples and working with the oyster aquaculture industry. His research experience has included the evaluation of multiple stream restoration projects via groundwater and surface water monitoring. Recent research has focused on understanding the extent and impacts of water salinization resulting from land-use and sea-level rise, how salinization alters saturated materials, and how that alteration relates back to surface water and groundwater quality. Ongoing salinization of freshwater resources is a major global challenge that has not yet been adequately addressed.

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 https://peerj.com/articles/2502/.
