Background and Interests
 
Dr. Jorgensen received a Ph.D. in Biochemistry from the University of Wisconsin in 1978, as well as an M.S. in Chemistry and a B.S. in Biomedical Engineering from Northwestern University in 1973. His current research interests include RNA silencing mechanisms in plants, applications of sense-RNA silencing to functional genomics, and chromatin-based control of gene expression (see Plant Chromatin Database)
