Visiting Scholars



Boudewijn Beltman was a Visiting Scholar at the Duke University Wetland Center during the 1997-98 academic year.  A faculty member in the Department of Plant Ecology and Evolutionary Biology at the University of Utrecht, The Netherlands, he studies the effects of chloride and sulfate on peat soil. While at the center, Beltman began a greenhouse experiment designed to investigate Everglades peat's ability to adsorb ions (chloride and sulfate) from solutions of different ionic strengths. This work will help describe phosphorus storage, release, and plant availability in peat soil and could be an important consideration in the restoration of fresh water ecosystems, specifically concerning the use of ion-laden water from the Rhine River to re-flood wetlands during droughts in the Netherlands.


Edward Maltby,  Emeritus Professor of Wetland Science, Water and Ecosystem Management at the University of Liverpool,, visited Duke University in October 2002 as a Nicholas Visiting Distinguished Scholar.  Maltby's visit was part of a growing collaboration between the Nicholas School of the Environment and overseas institutions. He is a widely respected advocate on key issues relating to translation of science for decision-makers, and he has authored or co-authored over eight boooks and 150 publications. During his visit to the Nicholas School, Maltby presented class lectures and took part in individual discussions with faculty and students. He also presented the first lecture of the 2002-2003 Duke Wetland Center Distinguished Speaker Series. Maltby has visited the Wetland Center several times in recent years, including a return visit as a Distinguished Speaker in 2011.




Jan Vymazal is Head of the Department of Applied Ecology at the Czech University of Life Sciences, Prague. He has been a regular visitor to the Duke University Wetland Center since his first visit to Durham.  Beginning in 1991, he conducted research in the Everglades looking to find the nutrient concentration threshold that alters plant species composition. In Prague, he works on constructed wetlands for wastewater treatment.  Vymazal notes that the work done by Duke researchers on the Everglades' natural wetlands, such as nutrient cycling, is easily transferable to the wastewater-related constructed wetlands he studies in Europe. Vymazal is a frequent visitor to the Wetland Center and has been named an adjunct member of the Nicholas School faculty. He is also an enthusiastic Blue Devils basketball fan.



Yongxing Yang is a professor at the Northeast Institute of Geography and Agricultural Ecology at Changchun, People's Republic of China.  He visited Duke during the 1999-2000 school year, dividing his time between the Wetland Center's Durham labs and the field station in the Florida Everglades.  DUWC Director Curtis Richardson said that Yang's visit was "an outstanding opportunity for the Duke Wetland Center to interact with one of the leading wetland scientists from Asia, who has been responsible for mapping the peatlands of China." In September 2000, Yang hosted Curt and Carol Richardson and DUWC Data Manager Mengchi Ho during a special tour to northern China sponsored by the Northeast Institute.



Ami Nishri is a senior scientist (emeritus) at the Yigal Alon Kineret Limnological Laboratory in Tiberius, Israel. His research insterest include biogeochemistry with an emphasis on nutrients, sediments, and salinity issues in Lake Kinneret and in the Jordan River drainage basin. His time at Duke in 2003 was in conjunction with a United States-Israel Binational Science Foundation project.



Tim Moore is a Professor in the Department of Geology at McGill University who studies the relationships between soil and the environment, particularly the regulation of fluxes of gases, nutrients and elements between the soil and the atmosphere, the biosphere and the hydrosphere and the effect of human activities and climate change. He visited the Wetland Center in Fall 2011 to conduct peat studies at the DUWC research sites in the North Carolina pocosins.



Lin Yuan is DUWC's Visiting Scholar for 2012-2013. She is Associate Professor at the State Key Lab. of Estuarine and Coastal Research (East China Normal University) in Shanghai. Her studies focus on wetland ecology, climate change effects on coastal ecosystem, and coastal zone management.



Jianqing Tian, Research Associate at the State Key Lab of Mycology at the Chinese Academy of Science Institute of Microbiology in Beijing, has been a Visiting Scholar at the Wetland Center since 2014. Tian's research focuses on microbial community structure in wetlands, with a recent emphasis on the microbial ecology of methanogens. During her time at Duke, her work will include studying the effects of drought on microbial population responses, carbon sequestration, and GHG losses in coastal wetlands of the Southeastern United States.



Moseki Motsholapheko is a senior research scholar in water resources management at the University of Botswana's Okavango Research Institute. His research focuses on the interface of human populations and the environment. He has most recently investigated effects of hydrology in the Okavango Delta on livelihoods and living conditions of the Delta's residents with the aim of finding ways to ameliorate the impacts of flood-related shocks. Motsholapheko came to the Wetland Center in 2015 through the auspices of the Duke Africa Initiative.



Paul Mensah is a researcher at Rhodes University's Unilever Centre for Environmental Quality in Grahmstown, South Africa. His research has focused on the assessment of environmental pollutants such as pesticides, metals, and endocrine disruptive chemicals (ECDs) on freshwater ecosystems. Mensah came to the Wetland Center in 2015 through the auspices of the Duke Africa Initiative.



Tereza Brezinova was a DUWC Summer 2015 Visiting Scholar.  on "The Effect of Flood Depth on Carbon Sequestration in Reedbeds," a joint project between the Duke University Wetland Center and the Czech University of Life Sciences Prague.



Jin'e Liu is a Visiting Scholar for the 2015-2016 school year. She is an Associate Professor in the School of Georgraphy Science at Nanjing Normal University in Nanjing, China. Dr. Liu's research focuses on soil organic carbon sequestration in salt marshes. During her time at Duke, she will join the Wetland Center's project on effects of drought on carbon sequestration and GHG losses in coastal wetlands.
