Recent Research/Educational Projects

Dr. Carlson's group conducts research in the areas of Genomics, Conservation Genetics, and Biotechnology. Current projects in The Schatz Center cover a wide range of topics from sequencing the chestnut genome to soil metagenomics of short rotation biomass crops.

Genomics

The organization of genes and genomes are studied through transcriptomics, genome sequencing, genetic linkage mapping, and metagenomics. This research identifies genes, DNA markers and quantitative trait loci governing growth, stress resistance, and plant-microbe interactions in hardwood tree species.

Conservation genetics

Genetic diversity is the foundation for biodiversity. DNA markers in the nuclear, mitochondrial and chloroplast genomes are used to study genetic diversity in forest trees and associated organisms.

Environmental tree biotechnology

Research is being conducted on the molecular basis of lignin synthesis and the response of trees to environmental stresses such as introduced pests and diseases, climate change, and pollutants. The goal for this research is environmentally friendly bioenergy production and ecosystem restoration.
