Justin Graham Alexander Whitehill
My research utilizes genomics approaches to enhance forest tree genetics and ultimately prepare our forests and tree species for current and future challenges presented by an ever-changing climate. Specifically, I am an expert in deciphering forest tree-insect/pathogen interactions from the ecological to functional genomic level. I work towards the development of novel pest management strategies against devastating forest pests through the application and integration of forest health genomics. Forest pest interactions with trees are relatively unexplored at the level of molecular mechanism. Some forest trees possess natural resistance to pests which include chemical and physical defense systems working together to enable tree survival. These mechanisms and defense systems are controlled and regulated by specific genes and gene families that contribute to the ultimate phenotypic expression of resilience traits. Once important genes/genomic regions are identified, I use functional and quantitative genomics approaches to develop pest management strategies to improve ecological and economic gains for the forestry industry and associated stakeholders.
