Section Head - Marine conservation

Leading a team of scientists working on marine protected areas (MPAs) and marine refuges in DFO's Gulf Region Science sector.

Fisheries and Oceans Canada
Moncton, NB

Current research and/or projects

  • Leading the scientific aspect of marine conservation files in Gulf Region
  • Collaborating with all regions nationally under the Marine Conservation Targets program (currently active until 2026)
  • Developping robust science-based monitoring indicators to assess the status of conservation objectives and inform adaptive management of protected areas.
  • Developping monitoring plans for Basin Head Marine Protected Area, and several marine refuges: Scallop Buffer Zones, Miramichi Bay Closure and some Cold-water coral Conservation areas (in collaboration with Quebec Region).

Research and/or project statements

  • Our role is to integrate available scientific knowledge and data, and generate new data to address gaps, in order to best monitor the status of conservation objectives in our marine protected area and refuges.
  • I value collaborative research and an ecosystemic approach where the sustainability and environmental impact of new marine conservation practises can be assessed as throughly as possible to avoid any unforeseen problems that result from them.
  • I believe that conserving and protecting marine ecosystems depends on several stakeholders, including the general public, and favour a clear communicative approach among all involved.

Education and awards

  • Natural Sciences and Engineering Research Council of Canada (NSERC) Postdoctoral Fellow at the University of Reading, UK, under the supervision of Drs Robert W. Jackson and Louise J. Johnson (July 2015-July 2016). Project title: Consequences of adaptive innovation in Pseudomonas spp. for physiology and plant colonization.
  • PhD in Life Sciences (Department of biology), Université de Moncton, NB, Canada, supervised by Dr Martin Filion. Successfully defended with special mention of excellence in June 2015. Diploma sanctioned in October 2015. Thesis title: Elucidation of the mechanisms involved in the biocontrol of common scab of potato by Pseudomonas fluorescens LBUM223, a producer of phenazine-1-carboxylic acid. Received the gold Governor General’s Academic Medal of Canada for the highest average of the postgraduate class of 2016.
  • BSc with specialization in biochemistry (May 2009, Université de Moncton, NB, Canada). Received the silver Governor General’s Academic Medal of Canada for the highest average of the undergraduate class of 2009.

International experience and/or work

  • Research scientist in root phytopathology at Agriculture and Agri-Food Canada, Saint-Jean-sur-Richelieu, QC (2016-2022).
  • Postdoctoral Fellow at the University of Reading, UK, under the supervision of Drs Robert W. Jackson and Louise J. Johnson (July 2015-July 2016)
  • MSc Internship (May-July 2010) at Utrecht University, Netherlands, supervised by Dr Corné Pieterse. Funded by NSERC (Michael Smith supplement). Project title: Exploration of genetic markers of induced resistance in potato (Solanum tuberosum) and Arabidopsis thaliana, following inoculation with the bacterial biocontrol agent Pseudomonas sp. LBUM223.
