Biological invasions directly impact economic and natural resources across Canada and worldwide. However, the abundance and distribution of species can vary from a few isolated individuals in some locations to hectares of near-monoculture elsewhere. Which genes allow populations to thrive and which drive it to extinction? How do the effects of these genes change across environments? These questions are addressed using a combination of methods from field ecology, statistics, bioinformatics and 'next-generation' sequencing technologies. Identifying genetic loci affecting survival and reproduction could lead to genetic screens for invasive genotypes or novel traits for crop improvement.

生物入侵直接影响加拿大和世界各地的经济和自然资源。然而，物种的丰度和分布可能各不相同，从一些地方的几个孤立的个体到其他地方的几公顷近乎单一栽培的物种。哪些基因使种群兴旺，哪些基因使种群灭绝？这些基因的影响如何在不同环境中变化？这些问题的解决使用的方法相结合，从现场生态学，统计学，生物信息学和“下一代”测序技术。确定影响生存和繁殖的遗传位点可能会导致对入侵基因型或作物改良新性状的遗传筛选。
