Research Interests

My research is focused on the ecological and evolutionary genetics of plants. To accomplish this research, my lab applies an interdisciplinary approach that utilizes methods from computational biology, molecular biology, genetics/genomics and forest ecology. Ongoing research in the lab is concentrated around three main themes: 1) dissecting how genetic variation of populations is structured across the landscape, 2) identifying process that have influenced the adaptation and evolution of populations and 3) understanding the genetic regulation of important ecologically and economically traits such as wood formation, response to abiotic stress and resistance to insects. These studies are primarily focused on undomesticated forest trees because forests are the foundation of many natural systems in the world, which society relies heavily upon for ecosystem services, forest products, and recreation.
