As a biologist and bioinformatician in the genomics team of the Canadian Wood Fibre Centre (CWFC), my role is to manage and analyze data on trees, at the genetic level (genotypes) and in their physical characteristics (phenotypes). Therefore, I develop databases such as TreeSource, the national platform for wood and trees quality, which holds nearly 7500 forestry research sites across Canada. I also develop computer programs to transform and analyze data received from service providers (e.g. genotyping data, SilviScan data, etc.).

Current research and/or projects

Principal project: manage and develop TreeSource. The goal of this national database is to regroup the largest collection of information on wood and trees quality in economically important species in Canada. Data available go from detailed description (geo-location, topography, ecology, soil properties, etc.) of about 7 500 forestry research sites across Canada, to microscopic tree physico-mechanical properties (wood density, microfibril angle, tracheid dimensions, etc.). Nearly 500 000 trees from 45 species have detailed individual measurements.

This project is an essential service to several significant research themes at the Canadian Wood Fibre Centre:

Silviculture, resource evaluation, genomics and growth and yield modeling.

Research and/or project statements

TreeSource contributes to the conservation and dissemination of science for the whole forest sector: the industry, academia, federal and provincial governments.

It contains exclusive information on wood quality, including physico-mechanical wood properties on nearly 11 000 trees, a unique reference on the topic.
