Principal Research Scientist

Principal Research Scientist located at the Central Experimental Farm (Ottawa, ON).

As an expert in micrometeorology and ecophysiology, leads projects and collaborates on scientific studies contributing to: 

- Develop and improve methodology for quantifying trace gas fluxes such as nitrous oxide, ammonia, methane and carbon dioxide;

- Quantify greenhouse gas emissions from agricultural practices at the field-, farm- and regional-scales using micrometeorological techniques and laser -based instrumentation;

- Verify process-based models describing 1) greenhouse gas emissions and ammonia volatilization from agricultural sources , 2) crop growth and evapotransiration;

- Quantify crop growth, biomass, water and nitrogen use efficiencies in response to weather and soil conditions using  micrometeorology, modelling and remote sensing (Earth observation).

- Evaluate the impact of field crop beneficial management practices and clean technologies on air quality with a special emphasis on nitrous oxide emissions and ammonia volatilization and deposition.

Research and/or project statements

Leads projects combining micrometeorology, Earth Observations (EO) and modelling to enhance the sustainability of rainfed field crop production and to quantify carbon dioxide, water vapour, nitrous oxide and ammonia fluxes in response to climate variations.

Enhanced the value of EO by providing insight on soil/crop descriptors retrieval and their assimilation in crop growth models to predict crop productivity and assess environmental impact related to crop production.

Led the creation of Identifying NEMO (nitrogen ecophysiologically modelled optimum). A model-based methodology  to derive strategic nitrogen application rates accounting for climate variations and soil properties and fully compatible with the assessment of reactive nitrogen release in the environment.

Principal Investigator of the Canada CFIA–Ottawa site of Joint Experiment of Crop Assessment and Monitoring (JECAM).

Led the creation of the GreenCropTracker software to analyze digital picture for extracting crop fraction and green Leaf Area Index to monitor crop growth  (https://www.flintbox.com/public/project/5470/).

As Principal Investigator, coordinated flux tower measurements in several environments in support to the National Research Council of Canada flux aircraft operations for the Boreal Ecosystem and Atmosphere Study (BOREAS), and for various research initiatives funded by Agriculture and Agri-Food Canada.

Education and awards
