Education:
B.S. Southern Oregon State College (1983)

Ph.D. Oregon State University (1990)
Administrative Duties:
As Department Head most of my activities are focused on supporting our students, faculty and staff as we try to excel in our teaching/learning, research, extension and outreach missions. I also represent the department in interactions with the College of Natural Resources, NC State University and a number of external stakeholder groups and individuals.
Courses:
My administrative schedule does not permit me to have principal responsibilities for courses. Previously, I taught tree physiology at the undergraduate and graduate levels.
Currently, I regularly teach modules in:
FOR 110 - Introduction to Forestry and NR 100 - Introduction to Natural Resources
FOR 252 - Introduction to Forest Science
FOR 411 - Forest Tree Genetics and Biology
FOR 603/803 - Seminar in Forest Research
FOR 725 - Forest Genetics
FOR 727 - Tree Improvement Research Techniques
HS 301 - Plant Propagation
HS 525 - Advanced Plant Propagation
Research Interests:
Molecular and genetic control of root systems in forest trees, vegetative propagation of forest trees, clonal forestry, forest regeneration

Langley, C., D.B. Neale, G. Peter, B. Goldfarb, C. Loopstra, M. Kirst and J. Davis. Association genetics and natural genetic variation of complex traits in loblolly pine. NSF. $5,902,035. September 15, 2005 – September 14, 2009.
The ADEPT2 project is aimed at determining the associations between natural genetic variation and complex traits (http://dendrome.ucdavis.edu/adept2). This is a collaborative project between UC Davis, North Carolina State University, University of Florida and Texas A&M University. Each partner is taking the lead on a part of the overall project and UC Davis is conducting all SNP discovery and genotyping. This will then be combined with the phenotyping being done at the partner institutes for analysis. Phenotype data is available or is being collected from five phenotypic groups, wood properties (UF), disease resistance (UF), drought resistance (NCSU), gene expression (TAMU) and metabolomics (UCD). From here we will have the foundation for looking into the diversity of the loblolly pine genome and for dissecting associations between genotypes and phenotypes.
Brunner, A.M., R. Meilan, S.H. Strauss, S. Givan and B. Goldfarb. New genetic tools for modifying tree properties to enhance carbon sequestration. US DOE. $1,202,725. October 1, 2003 – January 31, 2008.
This project is a collaboration with scientists at Virginia Tech, Oregon State and the University of West Virginia. Because of their rapid growth rate, poplar trees could be useful for carbon sequestration and/or woody biomass production for bioenergy. Sequestration could be enhanced by directing more assimilate to root systems and/or by modifying root system architecture to allow for greater adaptability on a wide range of sites. This project seeks to understand the genetic control of root architecture through study of transcriptional regulators--a class of genes that act as master switches in plant development and in plant responses to the environment. Because poplar is also a model tree species for the study of plant development, we have used the Populus genome sequence (website) to quantify gene expression using microarrays and to isolate candidate genes that regulate root formation. These genes have been modified to increase and lower expression levels and re-introduced into poplars to study the effects on root formation and development.
