Dr. Hallen is working with Dr. Steve Rier and Dr. Cynthia Venn on several water quality assessment projects on the Susquehanna River and Hunter’s Lake (Sullivan County, PA).
Research Interests: Stream ecology but mainly focus on the role that microorganisms such as algae, bacteria, and fungi play in regulating stream ecosystem function and how human impacts can alter these dynamics. My lab is currently investigating how impacts such as acid mine drainage from abandoned coal mines alters stream ecosystem functions such as the decomposition of organic matter and uptake and mineralization of nitrogen and phosphorus.
Dr. Venn is working with Dr. Steve Rier and Dr. Chris Hallen on several water quality assessment projects on the Susquehanna River and Hunter’s Lake (Sullivan County, PA).
Research Interests: Fluvial geomorphology and watershed hydrology; stream restoration; sediment transport and flow hydraulics; formation of island sand channel bed forms in the Susquehanna River; river-aquifer interactions and hyporheic exchange; hydrogeology of wetlands along the Susquehanna River; real-time monitoring of flow and water quality in the river; influence of river morphology and flow hydraulics on aquatic habitat; numerical and physical modeling of fluvial processes.
Research Interests: Stream ecosystem structure and function in response to landscape and watershed properties; Passive recovery, active restoration, and preservation of stream ecosystems; Land use trends of the eastern United States; Physicochemistry, macroinvertebrates, organic matter dynamics, and stream metabolism.
Research Interests: Rivers, fish and insect habitat use, Environmental Monitoring and Assessment, Environment-Industry Relations, and Exotic Species (introduction and control).
Research Interests: Coastal oceanography, hydrogeology, aqueous environmental geochemistry, and GIS.
Research Interests: Natural Stream Channel Design; zoological interests include research on the giant hellbender salamander, an inhabitant of streams and rivers in Pennsylvania, behavior, population dynamics, reproduction, growth, food habits, and genetic diversity).
Research Interests: stream ecology and restoration, wetland ecology and wastewater biology.
Research Interests: Systematic biology, limnology and phycology, ecology and biology of freshwater algae.
Research Interests: Ecology, vertebrate animal ecology.
Research Interests: Three-dimensional particle tracking velocimetry in homogeneous and heterogeneous porous material, groundwater and solute transport modeling, and bioremediation.
Research Interests: The biology and ecology of freshwater fish, in particular native coldwater species like the brook trout (Salvelinus fontinalis). Research projects involve assessing habitat enhancement, watershed protection, feeding ecology, and the life history of this coldwater species.
