Marilyn J. Roossinck

Professor of Virus Ecology, Department of Plant Pathology and Environmental Microbiology; Pennsylvania State University

Marilyn Roossinck has studied virus ecology and evolution since the late 1980s. Trained as a molecular virologist, she uses RNA viruses, as the most rapidly evolving entities on earth, to understand basic concepts in evolution, including symbiogenesis as a major driving force for viruses. Combining experimental work and field work/virus discovery she has a broad perspective on how viruses affect their hosts' interactions with the environment.

Profile continued

Marilyn J Roossinck received a B.A. degree in Molecular, Cellular and Developmental Biology, and in Evolutionary, Populational and Organismal Biology, from the University of Colorado in 1982.  She received her Ph.D. in Microbiology and Immunology from the University of Colorado School of Medicine in 1986.  She did a postdoc in plant virology at Cornell University, and joined the Samuel Roberts Noble Foundation as an assistant professor of Plant Biology in 1991.  In 2011 she moved to the Center for Infectious Disease Dynamics, Huck Institute of Life Sciences, at the Pennsylvania State University, as a full Professor, where she teaches a course in Virus Ecology.  She has published over 100 scientific papers, edited or co-edited two books, and written one popular press book on viruses. Her research includes experimental evolution of plant RNA viruses, biodiversity studies of viruses in wild plants, viruses involved in plant adaptation to extreme environments, and the ecology of persistent viruses of plants and fungi. Her research has been supported by the National Science Foundation and the US Department of Agriculture, as well as a number of private and local funding agencies.  She currently serves as an editor for the journals VIrus Evolution, Current Opinion in Virology, mSphere, and Advances in VIrology, and is a member of the editorial board for the Journal of General Virology and Virology.
