An interdisciplinary research team

Heejun Chang, Professor of Geography and Fellow of the Institute for Sustainable Solutions, PSU

Chang, the project PI, has expertise in integrated river basin assessment under the combined stresses of climate change and land development and spatial analysis of water-related ecosystem services. He employs a mixed approach of using simulation models and stakeholder involvement to help solve complex river basin problems. Chang will oversee the project and will lead the effort to develop a conceptual framework for modeling hydrologic and water system responses using modern spatial analysis. A more detailed profile of Chang is available here.

David Jay, Professor of Civil and Environmental Engineering, PSU

Jay, a physical pceanographer, has expertise in the influence of hydrodynamic processes on ecosystems. He conducts research in buoyant plume processes, estuarine circulation and salinity intrusion, suspended sediment transport, coastal tides, biophysical interactions, estuarine comparison and classification, human alteration of coastal environments, fisheries oceanography and turbulence/mixing in stratified flows.

Il-Won Jung, Post Doctoral Fellow with the Department of Geography and the Institute for Sustainable Solutions, PSU

Jung specializes in modeling potential climate change impacts on hydrological systems in the western U.S. and in South Korea. Much of his research has focused on quantifying uncertainty in such impact assessments, and on estimating potential changes in the frequency of extreme weather events, such as droughts and floods.

Martin Lafrenz, Assitant Professor of Geography, PSU

Lafrenz, a fluvial geomorpholgist, will assess the research gaps, both in terms of inadequate information and a lack of methodology, that prevent researchers from definitely linking stream reach-scale geomorphic patterns to watershed-scale landscape characteristics. Without this process-based linkage, it is difficult for managers to anticipate exactly how a particular land use decision may impact different types of stream habitats as well as how various stream restoration techniques may impact the surrounding watershed.

Hamid Moradkhani, Associate Professor of Civil and Environmental Engineering, PSU

Moradkhani is an engineering hydrologist who specializes in Integrated Water Resources Analysis and Management, Climate Change Impact Assessment on Water Resources, Hydrologic Data Assimilation Methods, Uncertainty Analysis Methods, Hydrologic Modeling and Forecasting in short and long lead time scales, Flood Inundation Modeling, and Remote Sensing applications in Water Resources systems. Dr. Moradkhani will participate in knowledge-gap identification and synthesis paper development, and will participate in potential proposal preparation.

Yangdong Pan, Professor of Environmental Science and Management, PSU

As an aquatic ecologist, Pan has expertise in water quality monitoring and assessment. He uses a suite of biological indicators and indices to assess stream/river ecosystem integrity. Pan will lead the effort on modeling the relationships between stream/river biota and watershed characteristics using multivariate analysis and predictive models.

Vivek Shandas, Associate Professor in the Nohad A. Toulan School of Urban Studies and Planning, and Fellow of the Institute for Sustainable Solutions, PSU

Shandas specializes in urban environmental planning and assessment. He examines the relationship among environmental change, human and institutional response, and the effectiveness of management actions. He is trained broadly in natural and social sciences, which defines his approach to conducting collaborative transdisciplinary projects. A more detailed profile of Shandas is available here.

Angela Strecker, Assistant Professor of Environmental Science and Management, PSU

Strecker's research interests broadly involve how patterns of biodiversity are structured by local and regional processes, such as dispersal, invasive species, and other anthropogenic stressors. Ultimately, this work leads to the question of how ecosystem function may be affected by these processes, which have been substantially altered by human activity in the past century. In general, she uses the combined approach of field surveys, small- and large-scale experiments, and statistical modeling to test her hypotheses.

Mark Sytsma, Professor of Environmental Science and Management and Associate Vice-president for Research at PSU

Sytsma brings expertise in limnology and the biology and management of aquatic invasive species to the project. He studies the biology and ecological effects of invasive species, and the role of vector strength and propagule pressure in biological invasions. His work is typically focused on development of management solutions to invasive species and lake and reservoir water quality.

Alan Yeakley, Professor of Environmental Science and Management and Fellow of the Institute for Sustainable Solutions, PSU

Yeakley, a watershed hydrologist and an urban ecologist, has expertise in process scale watershed hydrology and ecology studies, with a focus on riparian ecosystems. He tests questions of ecosystem function and integrity, and works with social scientists to better understand how effective landscape scale policy and management can be for natural resource conservation. Yeakley will participate in the project by relating land use and land cover patterns, as well as social parameters, to riparian and stream ecosystem ecological and hydrological responses.
