Research interests:
Ecological function of forest microorganisms at community and species level, speciation and evolution of forest fungi and bacteria, application of bioinformatic tools to study microbial community.

Current Project:
Metagenomic analysis of microbial communities in the forest soils of British Columbia
    Terrestrial microorganisms play essential roles in global energy recycling. It is estimated that one gram of soil may contain several thousand to a million genomic species. However, less than 1% of these organisms are culturable and consequently a huge number of soil microorganisms remain to be discovered. In British Columbia, two-thirds of the land is forested. Healthy and intact microbial communities are the key factor in ensuring soil fertility. My research sites are located at Williams Lake and Smithers in BC forests. Using a metagenomics, phylogenomics and physico-chemical analyses of soil, I am investigating the structure of microbial communities (archaea, bacteria, and fungi) and their key metabolic processes within the terrestrial depth continuum. Especially, the genes involved in the biogeochemical cycling of carbon and nitrogen will be a key focus.
    The established datasets in this study will be used to construct a prototype microarray that can serve as a tool for monitoring the structure of microbial communities in various habitats undergoing human disturbances and global climate changes. The data can also help governments develop sustainable soil management practices. The constructed fosmid library, which will contain a huge number of environmental genomes, will be an asset for functional screening and may lead to the rapid discovery of genes with great biotechnological value, such as those expressing antibiotics, proteases and lipases.
