Graduate Faculty Updates
Please help us welcome our newest WRS graduate faculty!
Ph.D. Aquatic Ecology, Kent State University, 1993
Dr. Ralph Garono is current a Research Associate at the University of Minnesota-Duluth. He has taught undergraduate courses at several institutions. He is trained in biochemical limnology (e.g., the role that phosphorus limitation plays in structuring planktonic communities) and in aquatic entomology. His current research interests focus on assessments, at multiple spatial and temporal scales, of aquatic and marine ecosystems. His research projects include: the use of aquatic insects as a wetland assessment tool; GIS-based watershed assessments; the use of GIS-based models to evaluate alternative land use scenarios; and, the use of hyperspectral imagery to map landscape patterns in intertidal estuarine vegetation.
Dr. Garono is currently coordinating a NOAA-funded project team composed of researchers from MN DNR, NRRI, and The Nature Conservancy that is looking at the role that climate and land use changes have on the flow patterns within Lake Superior North Shore tributaries. This study is developing computer models that will describe the patterns in water flow under several climate/land use change scenarios. The resulting flow metrics will then be used to predict the impact of these hydrological changes on in stream biota. In another series of studies, Dr. Garono is measuring wintertime patterns of dissolved oxygen concentration (DO) in the lower St. Louis River. Low DO can be detrimental to fish and other aquatic organisms, and is important in understanding patterns of nutrient availability. Relatively large areas of low DO have been measured both in the winter and in the summer in the St. Louis River. Finally, Dr. Garono is working with other researchers at NRRI to develop techniques to map and assess the ecological role that vernal pools play in upper Midwest forests.
He currently is the chair of the Society of Wetland Scientists Human Diversity Committee.
Texas A&M University, Ph.D.
Dr. Kathryn Schreiner is an Assistant Professor at the Large Lakes Observatory (LLO) at the University of Minnesota-Duluth. Her research interests include carbon cycling and storage in lakes and lake sediments, the quantification and identification of terrestrial carbon sources to aquatic and marine systems, and the impacts of environmental change (climate warning, land use change, invasive species, etc.) on carbon cycling.
University of Pittsburgh, Ph.D.
Dr. Byron Steinman is an Assistant Professor in the Department of Earth and Environmental Sciences and the Large Lakes Observatory (LLO) at the University of Minnesota-Duluth.
As a paleoclimatologist and paleolimnologist, my research is primarily focused on reconstructing how climate has changed through time in various regions around the world including the Americas (North, South, and Central) and Asia using geochemical analyses of lake sediment. I use mathematical models of the lake-catchment-climate system to provide a quantitative basis for interpreting the lake sediment records. I also use global climate model simulations to provide insight into the configurations of the ocean-atmosphere system that produced the climate conditions inferred from the lake sediment records.
M.S. Wildlife Management, West Virginia University, 1990
Tom Hollenhorst is a landscape ecologist with the EPA Mid-continent Ecology Division. He received a M.S. degree in Wildlife Management from West Virginia in 1988. Tom Joined the EPA-MED lab in 2008 after working at the Center for Water and the Environment at the Natural Resources Research Institute (NRRI), University of Minnesota, Duluth, for the previous ten years. Tom has worked on a wide variety of projects involving GIS and remote sensing technologies. He has used these technologies for assessing watershed stress and condition around the Great Lakes and assessing and quantifying ecosystem goods and serves provided by coastal ecosystems. He has used LiDAR data to further characterize watersheds, and forest lands within watersheds to assess relationship between various watershed characteristics and hydrology. More recently Tom has been working to deploy an autonomous underwater glider (http://www.webbresearch.com/slocumglider.aspx) in the Great Lakes for continuous water quality measurements in the nearshore area, which then will be related to watershed characteristics and stress.
University of Waterloo, Ph.D.
Dr. Ted Ozersky is an Assistant Professor in the Department of Biology and the Large Lakes Observatory (LLO) at the University of Minnesota- Duluth. His research interests include the effects of environmental change on nutrient dynamics, food webs, and community structure in large lakes; winter and under-ice ecology of large lakes; ecosystem effects of aquatic invasive species; and food web structure and contaminant trophodynamics.
Ph.D. Chemical Engineering, Princeton University, 2012
Dr. Santiago Romero-Vargas Castrillón is an Assistant Professor in the Department of Civil, Environmental, and Geo-Engineering at the University of Minnesota- Twin Cities. His major research interests include membrane-based processes for water treatment; membrane fouling; environmental nanotechnology; environmental colloid and surface science.
Ph.D. ESPM-Ecosystem Sciences, University of California-Berkeley, 2003
Dr. Kyungsoo Yoo is an Associate Professor in the Department of Soil, Water, and Climate at the University of Minnesota-Twin Cities.
My research focuses on integrating the two fields of geomorphology and biogeochemistry through mathematical and empirical methods to better understand the carbon cycle and weathering processes in soils. My current research activities on weathering and carbon cycle are conducted at the Feather River Basin, California (tectonics gradient), the Piedmont Pennsylvania (land use gradient), SW. Australia (climate gradient), and N. Minnesota (biological invasion gradient).
