Rate My Professor Tia-Lynn Ashman

Tia-Lynn Ashman is a Distinguished Professor of Evolutionary Ecology in the Department of Biological Sciences at the University of Pittsburgh. She received her Ph.D. in 1991 from the University of California, Davis, under the supervision of M.L. Stanton, and completed postdoctoral studies with D.J. Schoen at McGill University. She joined the University of Pittsburgh faculty in 1994 and has remained there for nearly three decades, leading the Ashman Lab focused on the evolutionary ecology of flowering plants. Her research examines the genomic and functional consequences of polyploidy and hybridization, using wild strawberry (Fragaria) species as model systems to explore biodiversity origins. Additional investigations address the ecological and evolutionary processes leading to separate sexes and sex chromosomes, as well as the roles of plant-pollinator, microbial, and viral interactions in shaping phenotypic evolution, life history traits, mating systems, and flowering plant community structure. Studies span diverse habitats including serpentine seeps in California, biodiversity hotspots in Hawaii and Mexico, urban areas in Pittsburgh, and sites in Germany, employing ecological experiments, population and quantitative genetics, phylogenomics, and transcriptomics.
