Nutrients cycles and eutrophication, especially the biogeochemical processes at water- sediment interface that control the internal loading of nutrients.
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
My research focuses on the effects of the freeze-thaw cycles on carbon, nitrogen and phosphorus speciation dynamics across the reactive interfaces in agroecosystems.
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.
My research focuses on the role of winter soil processes in affecting soil microbial and geochemical dynamics and on the export of carbon and nutrients to groundwater under changing climate conditions.
Visiting from Tianjin University from September 2018 to February 2019
My research project focuses on the influences of dammed reservoirs on a river’s phosphorus (P) load and bioavailability.
I am a PhD student with a background in hydrogeology. I am interested in the quantification of phosphorus export from stormwater management systems into the aquatic ecosystems, especially during extreme climate events. My research focuses are:
I am a PhD student in the multidisciplinary field of ecohydrology. I have a strong interest in exploring and assessing phosphorus (P) retention performance of stormwater management (SWM) systems in urban areas, especially under the context of climate change. My research interest focuses on:
My research focuses on the phosphorus (P) transformations, speciation, bioavailability, retention and mobilization within stormwater bioretention cells in cold climates. My research objectives are to:

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.
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.
