Research professional in agri-environment

My work consists in leading water management and water quality research and development studies on agricultural land to improve the agroecosystem's productivity and sustainability.

Current research and/or projects

My research and development activities and collaborations aim principally at developing and promoting beneficial management practices with the agricultural producers to better manage and protect the water resource.

Research and/or project statements

  • Science, adoption and adaptation of pesticide rinsate biobeds to support Canadian agro-ecosystems​ resiliency and to protect water resources. (2018-2021).
  • Assessment of the efficiency of stormwater ponds in intercepting pesticides (herbicides, insecticides and fungicides) and nutrients (nitrogen and phosphorus) from surface runoff and tile-drain water in the St. Pierre Lake Basin in support of the St. Lawrence Action Plan. (2016-2021).
  • Interdisciplinary research laboratories in resilient agri-ecosystems: Frelighsburg, Sherbrooke and Missisquoi Bay. (2017-2020).
