Curriculum Vitae


My research focuses on coastal dynamics and the quantification of its ecological impacts, particularly those in large lakes and the coastal ocean, where stratification and the Earth’s rotation play a dominant role. I study the inner shelf response to wind and surface waves, upwelling dynamics, coastal-trapped waves, formation and transport of harmful algal blooms.
I am particularly interested in surface waves, internal waves, lake and ocean currents, transport of water and sediments and contaminants, and changes in the geomorphology. I use field observations and numerical models to study coastal systems, and develop further understanding of the processes that affect coastal embayments, coastal oceans, estuaries and rivers.
My current research site is Toronto Waterfront and the complex system of embayments of Toronto Harbour, for which I am developing a high resolution model based on unstructured mesh.
I am also interested in renewable energy, and impacts on the environment, specifically, those related to marine tidal current turbines and offshore wind turbines.

2015-present Ministry of Environment Conservation and Parks, 125 Resources Rl, Toronto, ON M3P 3V6
Senior Project Scientist Water Modelling

I develop thri dimensional integrated water circulation and water quality numerical models for the Laurentian Great Lakes.

2015-2017 University of Toronto Scarborough, 1265 Military Trail, Toronto, ON M1C 1A4
Post-doctoral Researcher, Mitacs Elevate Fellow

I developed a high definition integrated water circulation and water quality 3D numerical model for the Toronto Waterfront in collaboration with Toronto and Region Conservation Authority and Environment Canada under the umbrella of the Remedial Action Plan, which also has as stakeholders the Ministry of Environment and Climate Change Ontario, and City of Toronto. The project is partially funded by Mitacs Elevate, which is a very competitive two-year research program for postdoctoral fellows, in which participants lead and undertake an industrially relevant research project.

  • The project uses the Delft3D-FM (flexible mesh) integrated 3D modelling suite with the wave, sediment transport and morphology, and water quality modules.
  • The model simulations run in parallel hyper-computing clusters using MPI and OpenMP techniques on partitioned meshes.
  • The model based on existing bathymetry is operational and calibrated.
  • Created in Python post processing and visualization tools for Delft3D-FM model results.
  • I am currently evaluating several scenarios that aim to minimize the impact of urbanization developments on the water circulation, water quality in the embayments of Toronto Waterfront. Several climate change scenarios are also evaluated.
  • Used the model to determine the thermal regimes in Toronto Harbour system of embayments to help optimize current restoration work and the creation of new fish habitat.
  • Large datasets of recorded data were mined to provide inputs in the hydrodynamic model and coupling with atmospheric model was done statically through the model output files.
  • Used Geographical Information Systems software to integrate geospatial data into the model.
  • Created semi-annual financial reports and managed budgets.

2011-2014 University of Toronto Scarborough, 1265 Military Trail, Toronto, ON M1C 1A4

Research Associate, Ph.D. Fellow

I assessed the mechanisms that contribute to the flushing and thermal regimes in several coastal embayments of the Great Lakes, specifically in Lake Ontario and Lake Huron. Analysis of water currents, water levels and temperatures demonstrated that strong water level fluctuations may dominate the exchange flows in the shallow coastal embayments, which contrasts with the conventional wisdom that water circulation in coastal embayments of the Great Lakes is always dominated by baroclinic processes driven by differential heating and upwelling events.

  • Designed and implemented freshwater monitoring projects and used data analysis techniques.
  • Deployed monitoring instruments, such as arrays of benthic, surface and water column thermistor chain loggers, acoustic Doppler current profilers, water level loggers and DO and TP sensors.
  • Developed analytical and numerical models (Delft3D and in-house) to create the mathematical frameworks for data interpretation. Used statistical analysis for cases where the complexity of the problems did not allow a direct mechanistic approach.
  • Performed data analysis on water levels, wind waves, velocity and temperature time series, fish migration data and interpreted the results within the mathematical and model frameworks.
  • Written grant proposals, and managed budgets for research grants. Supervised and mentored graduate and undergraduate students.
  • Created complex data analysis and visualisation tools in Python.
  • Created reading and processing tool in Python for RDI Teledyne acoustic Doppler current profiler data files.
