Although the major focus of our research group is in the area of environmental geochemistry, the work done by members of my group is multidisciplinary and multifaceted. We have interests in the earth's chemical environment and how it is affected by physical, biological, geological and anthropogenic processes.  Currently the research in our group focuses on a number of different research areas.  As you can see on our personnel page, our research group includes professional scientists, graduate students, and undergraduate students.

Since my graduate student days, I have had an interest in the transport and fate of trace elements, especially trace metals in aquatic systems. Working with John Olesik at the Trace Element Research Laboratory in the School of Earth Sciences, my students and I continue this type of work. The researcj involves both the investigation of trace metals as "pollutants" and also as important micronutrients to biological systems. In addition, we use trace elements, stable isotopes, and even major elements to follow water movement through surface and near-surface systems.

With my colleague, Dr. Anne Carey, our group has been involved in the investigation of the relationship between chemical and physical weathering in alpine regions, especially on tectonically active oceanic islands such as New Zealand, Taiwan, and most recently Panama and Northern Spain.  This work has also evaluated the role of these types of watersheds in transporting organic carbon to the world’s oceans. Results of these investigations suggest a strong correlation between chemical and physical erosion, and implies that tectonic uplift as well as rainfall are extremely important in driving chemical weathering.

Another area of interest lies in the impact of both agricultural and urbanization on surface water quality.  Recently the group has worked in such places as the Chattahoochie River in Atlanta, GA, as well as the Scioto River system here in Ohio, in order to quantify the impact of urban runoff and sewage input on river water quality.  Here in Ohio, we have attempted to discern between agricultural impact and urban sources on the flux of many elements into the Scioto system.  In the past few years we have also developed detailed watershed mass balances of nitrogen for rather large river systems like the Alabama-Mobile. Currently, we have students working on the trace metal geochemistry of small urban streams in order to assess how small variations in land type impact water quality. We have also just finished a large, interdisciplanary plot-scale project to assess how variations in agricultural practices impact chemical weathering and carbon transport.

Finally, our research group has been involved for 20 years in the McMurdo Dry Valleys Long-Term Ecological Research (MCM-LTER) project (www.mcmlter.org).  We are working with a group of glaciologist, hydrologists, soil scientists and ecologists in order to determine the structure and function of this polar desert ecosystem.  The MCM-LTER is currently in its twelfth year of existence and we have recently learned that the project will continue for at least another six years.  Our group is responsible for much of the geochemical and biogeochemical work as well as the investigation of the role of climate change on the development of the ecosystem.  This work is diverse and multi-disciplinary.  For example under the guise of MCM-LTER, I have had students investigating the atmospheric mercury flux in the Antarctic, the processes responsible for CaCO3 accumulation in polar desert soils, and the geochemistry and quantity of sediment transport from alpine glaciers into the closed-basin lakes of the dry valleys. We have used non-traditional stable isotopes of Li and B to better understand solute sources to the aquatic environmets. Currently, we are using more traditional stable isotopes such as dD, d18O, and d13C to describe in-situ stream processes. Within the scope of this program our group has also been heavily involved in K-12 education and outreach.

Although being director of the School of Earth Sciences and teaching introductory geochemistry keeps me very busy, I still find enough time to be involved in the research activities of our group.  By reading the statements of our group of students and research staff, you will get a better understanding of the diversity and excitement of the work with which we are involved.

Finally, we have recently expanded our Antarctic research activities to include the investigation of sub-glacial biogeochemistry and the role of salt accumulation in soils to determine its relationship to the distribution of biota, as well as to provide relative ages of past glacial history.
