Ms. Harrison is Associate Professor at the University of Georgia's College of Environment and Design, and focuses her research on the work of Robert Marvin, a modernist landscape architect who practiced from the pivotal years of the late 1940's until his death in 2001. Her conference papers and publications have argued that, unlike many early modernists, his work responded to regional concerns of his native southeastern landscapes. She has noted that, as a passionate spokesman for environmental issues, his enduring contribution has been his influence on the succeeding generation of practitioners, in both architectural and landscape architectural professions.
Other research topics include a recent study of the significance of the Wormsloe State Historic Site as a cultural landscape. Ms. Harrison’s thesis topic considered the historical relevance of the Shenandoah National Park's Skyline Drive.
A registered landscape architect, Ms. Harrison practiced in the southeast for 16 years within a variety of sectors, including institutional, commercial and residential, prior to beginning her teaching career. She has been recognized with both University and College teaching awards. She holds an MLA from the University of Virginia.
