SUMMARY OF RESEARCH DIRECTIONS

Dr. Jeffrey Dean is Professor of Forest Biotechnology in the Warnell School of Forestry and Natural Resources at the University of Georgia. Trained in plant biochemistry and with an extensive background in plant cell wall formation and biodegradation, in recent years Dr. Dean's research has increasingly focused on the use of genomic technologies to study wood formation, as well as a host of other developmental processes and environmental responses in forest trees, especially pines and other conifers. His research team was one of the first in the world to apply Serial Analysis of Gene Expression (SAGE) in plants where they used it to identify genes differentiating juvenile and mature wood, as well as genes that might be useful for remediation of environmental contaminants, such as TNT and other explosives.

More recently his group has completed preparation of a 26,000-element cDNA microarray for the assessment of gene expression in loblolly pine. Dr. Dean is the Principal Investigator for a new international project at the DOE Joint Genome Institute, which will greatly expand the public collection of known conifer genes (see news item), and is co-PI on a new $6 million project from the USDA that will translate conifer genomic information into tools that can be used in conifer tree improvement programs (see CTGN). He is also one of the lead organizers for an international effort to fully sequence a conifer genome (CGN).
