Lu Huang

PhD Student

Research Interests

Nutrients cycles and eutrophication, especially the biogeochemical processes at water- sediment interface that control the internal loading of nutrients.

Igor Markelov

Igor Markelov

PhD Student

I am a PhD student in the multidisciplinary field of water sciences. I have a particular interest in applying models to understand the coupled biogeochemical cycles across media and scales. My interests are

Heather Townsend

MSc Student

My research focuses on the effects of the freeze-thaw cycles on carbon, nitrogen and phosphorus speciation dynamics across the reactive interfaces in agroecosystems.

Tamara Van Staden

Tamara Van Staden

MSc Student

Anthropogenic phosphorus (P) inputs into agricultural soils have exceeded crop demand for decades. The resulting release of the excess P to surface water contributes to eutrophication, including the occurrence of harmful algal blooms (HABs), with severe threats to drinking water security and aquatic ecosystems.

Ali Reza Shahvaran

Masters Student

Ali  Reza Shahvaran 

I joined the Earth Sciences (Water) program in the Department of Earth and Environmental Sciences at the University of Waterloo and ReSEC Lab at Wilfrid Laurier University in September 2021. My current thesis is a part of the GWF Urban project. It focuses on studying the retrieval algorithm of Cladophora and Chl-a concentration using remote sensing data to calibrate the developed algal growth model of western Lake Ontario. 


Amir Reshadi

PhD Student

Educational/Research background:

As a Ph.D. student at ERG, my main focus is on the spatial distribution of microplastics in the Grand River Watershed (GRW), as well as the response of riverine microplastic loadings to precipitation.

I received my master of science in environmental engineering at K. N. Toosi University of Technology. My previous research has covered a variety of environmental topics, with an emphasis on water engineering.
