Kwok P. Chun (Sun) has a first class degree from the University of Hong Kong and holds a PhD and MSc in Environmental Engineering with distinction from Imperial College London. Before joining the CERC program, Sun worked for consultants Arup and the Hong Kong Polytechnic University.  

Chun’s research interests are in statistical downscaling of climate scenarios for the assessment of nonstationary hydrological characteristics, including flood and drought. As the future hydrological cycle is uncertain under anthropogenic influence, Sun’s current projects will qualify and quantify risks, extremes and irreversible change related to natural processes in Canada and other parts of the world.

Description:


Uri Nachshon joined the Global Institute for Water Security in November 2011. He holds a first degree in Geology and a MSc and PhD in hydrology from Ben-Gurion University, Isreal. Nachshon's research interest is in salt dynamics in hydrological systems and the feedback interactions between soil properties, evaporation processes, and salt precipitation. Climate and land use change result in changes to hydrological systems, thus changing the spatial distribution of salts and solutes in watersheds. Understanding these processes is important to predicting and coping with future salinization.

Rebecca NorthPost-Doctoral Fellow(306) 966-4439rebecca.north@usask.ca

Organization:


Department of Biology, College of Arts & Science

Description:


Rebecca North is a limnologist who focuses on freshwater ecosystems in the context of eutrophication, climate change, invading species and multiple ecosystem stressors. Her research examines the effects of humans and climate change on aquatic ecosystem productivity at the organism level of primary producerts (ie, algae). This research is field-based and focuses on the lower food web (such as algae and bacteria). 

Rebecca completed her PhD in Limnology at the University of Waterloo in 2008. Her dissertation highlighted the important interrelationships between macronutrients and micronutrients as potential controls on freshwater primary productivity. As a post-doctoral fellow at Trent University (2008-12), she continued her work on eutrophication issues, specifically that agricultural land use can have a significant effect on phosphorus bioavailability and that high rates of under-ice primary production may challenge the current paradigm of lake metabolism. 

She is a member of the International Association of Theoretical and Applied Limnology (SIL), American Society of Limnology and Oceanography (ASLO), Phycological Society of America (PSA), International Association for Great Lakes Research (IAGLR) and Society of Canadian Limnologists (SCL).
