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.
I am a Water Resources Engineering PhD graduate from University of Waterloo.

Carbon dioxide (CO2) emissions from soils comprise a major component of the global carbon cycle. The responses of soil CO2 fluxes to changes in environmental conditions remain unclear but are critical for predictive modeling of global carbon fluxes with climate change.
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 project focuses on the influences of dammed reservoirs on a river’s phosphorus (P) load and bioavailability.
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.
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:
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 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 in the multidisciplinary field of ecohydrology. I have a strong interest in exploring and assessing water pollution issues by using knowledge and tools from various disciplines. My research interests are focused 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:
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:
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.
Nutrients cycles and eutrophication, especially the biogeochemical processes at water- sediment interface that control the internal loading of nutrients.
Visiting from Tianjin University from September 2018 to February 2019
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 role as a Research Biogeochemist is to support experimental, field and model-based research activities within the research group.
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.
