My research focuses on the biogeochemistry of soils, sediments and aquatic ecosystems, the cycles of water, carbon, nutrients and metals, global change, geobiology, chemical hydrology, water-rock interactions and environmental modeling. At the University of Waterloo, I lead the research program in ecohydrology.

My research focuses on elucidating the thermodynamic controls (bioenergetics) on the biogeochemical cycling of carbon, nutrients and metals. Microbial bioenergetics applies thermodynamic principles to quantitatively describe energy transformations and utilization to predict reaction rates and microbial growth.
I am a Water Resources Engineering PhD graduate from University of Waterloo.

My research focuses on the assessment and modelling of aquatic ecosystem services, integrating hydro-ecological and socio-economic data and information to support the sustainable management of freshwater, estuarine and marine ecosystems.
My research foucuses on nitrate pollution in ground- and surface water, which is of major concern in agricultural areas subject to a massive use of fertilizers. I aim to predict the evolution of nitrate concentration in headwater catchments depending on future agricultural scenarios.
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 project focuses on the influences of dammed reservoirs on a river’s phosphorus (P) load and bioavailability.
My study interests cover the sediment-water interaction and its constraints on the hydrogeochemistry of geo-contaminants (As, F, I, U) in groundwater, the interactions among organic matter, S and Mn/Fe minerals and consequent influence on the fate of environmentally relevant trace elements in the near-surface environments, the design of environmental biosensors for on-site detec
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:
Nutrients cycles and eutrophication, especially the biogeochemical processes at water- sediment interface that control the internal loading of nutrients.
Serghei’s primary research interest is to study the interaction between physical and biogeochemical processes in lakes using a combination of numerical modelling and field studies to investigate specific processes of interest, such as:
Phosphorus is an essential and often limiting nutrient for the growth of plants and phytoplankton. Excessive loads of phosphorus in aquatic environment can result in accelerated eutrophication. Beside the anthropogenic phosphorus input, some internal biogeochemical factors can play role for the mobilization of phosphorus from sediment into surface waters.
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.
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
Visiting from Tianjin University from September 2018 to February 2019
My research interest is on the fate and transport of contaminants (such as pesticides, petroleum hydrocarbons, metals, fertilizers and landfill leachate) in the subsurface environment.
My research interests include biogeochemical processes in subsurface environments, especially microbially-mediated processes and the implications of these processes for ecosystem functions including carbon use efficiency and respiration.
The primary area of my research is Water Resources and Environmental Remediation. I have employed reactive transport and mass transfer models as well as field and laboratory experiments to explore fate and transport of subsurface contaminants resulted from different sources such as petroleum hydrocarbons and landfill leachate.
My research focuses on the reactive interfaces in agroecosystems, that is, areas in the landscape characterised by steep gradients in chemical, physical, and biological properties and are “hot spots” of biogeochemical activity.
My primary research interests lie at the intersection of Environmental, Earth, and Computational sciences, and more specifically involve developing and employing computational tools for modeling the spatio-temporal dynamics of biogeochemical/ecohydrological processes at the soil-water interfaces inside the vadose and groundwater zones.
My research focuses on the effects of the freeze-thaw cycles on carbon, nitrogen and phosphorus speciation dynamics across the reactive interfaces in agroecosystems.
My research focuses on investigating winter changes in temperature and precipitation on the soil carbon cycle on various Canadian wetlands and permafrost regions.
