About

I have a strong background in the science and practice of molecular biology of aquatic organisms, namely marine bivalves, freshwater and marine fishes. My main research interests and expertise include genetic and QTL mapping, population genetics and parentage analysis. I have also worked in biodiversity assessment of the estuarine meiofauna using ultra deep sequencing (454) technologies. I recently started to develop an interest in bivalve genomics.

Education

2004-2007: Ph.D. (Bangor University, U.K.). Genetic linkage mapping in the blue mussel Mytilus edulis and the European flat oyster Ostrea edulis, and the search for Quantitative Trait Loci of resistance to a disease in O. edulis.
Supervisors: A.R. Beaumont (Bangor University), P. Boudry and S. Lapègue (Ifremer, France).

2002: M.Sc. in Biological Oceanography and Marine Environment, Area of Specialisation: Population dynamics (University Pierre and Marie Curie, France).

2000: B.Sc. in Biology of Populations and Ecosystems (University Pierre and Marie Curie, France).

Previous postdoctoral research projects:

  • Invasion genetics of feral populations of the Pacific oyster in the British Isles inferred from microsatellite markers and mitochondrial DNA. Evaluation of its ecological impact around the Atlantic coasts of Europe (Bangor University, School of Ocean Sciences, UK). Funding: Interreg Atlantic Area Programme – SEAFARE project.
  • Identification of plaice eggs and larvae in stomach contents of putative predators using real time PCR instrument and Taqman probes (Bangor University, School of Biological Sciences, UK). Funding: Defra - subcontract with CEFAS Lowesoft.
  • Assessment of meiofaunal biodiversity in estuarine ecosystems by massive parallel sequencing (Bangor University, School of Biological Sciences, UK). Funding: NERC. This project aimed at linking deep sequencing (454) data and morphological taxonomy with meiofaunal biodiversity in estuarine ecosystems.
  • Comparison of genetic variation in European flat oysters from wild, pond-produced and hatchery-produced stocks (Bangor University, School of Ocean Sciences, UK). Funding: Interreg IIIB European project 201- AAAG 2.
  • Development of microsatellite markers in two bivalve species, the European flat oyster Ostrea edulis and the blue mussel Mytilus edulis (Bangor University, School of Ocean Sciences). Funding: Interreg IIIB European project 201- AAAG 2.

Research

Research themes:

  • Genetic and QTL mapping of marine bivalves
  • Parentage analyses and pedigree reconstruction
  • Population genetics of aquaculture marine bivalves species
  • Assessment of biodiversity of microbial communities, using metagenetics / metabarcoding approaches

Welsh Assembly Government

I am currently involved in the GMEP (Glastir Monitoring Evaluation Programme) project, commissioned by the Welsh Government, which aims at providing a scientifically-rigorous approach to the monitoring and evaluation of the new sustainability land management scheme, Glastir (http://wales.gov.uk/topics/environmentcountryside/farmingandcountryside/farming/schemes/glastir/?lang=en). My role in this project is to: i) assess the biodiversity of soils microbial communities (bacteria, fungi, protists), using traditional molecular methods (T-RFLP) and new metagenetics / metabarcoding approach (Mi-Seq Illumina high-throughput sequencing); ii) explore changes in below-ground diversity in response to broad-scale Glastir measures.
