She was a postdoctoral researchfellow at the Carnegie Institution of Washington in the Department of Embryology from 1980-1982.[9] She joined the faculty at University of Georgia (UGA) in 1983 as an assistant professor of botany becoming a full professor in 1992.[9] She was named Distinguished Research Professor in 1994 and Regents Professor in 2005.[9]
Her research[5] focuses on identifying plant transposable elements and determining how they contribute to gene and genomeevolution.[9][6][7] Her work has deciphered how transposable elements generate genetic diversity and attain high copy numbers without killing their host.[1] Her laboratory demonstrated that elements could function as introns and that retrotransposons are the major cause of spontaneous insertion mutations in maize. In the genomics era her laboratory pioneered the computational analysis of transposable elements, culminating in the discovery of miniature inverted repeat transposable elements (MITEs), the element most frequently associated with plant genes.[1] As a Howard Hughes Medical Institute (HHMI) Professor, Wessler adapted her research program for the classroom by developing the Dynamic Genome Program where incoming freshmen experience the excitement of scientific discovery.[1][12]
