Dr. Tia-Lynn Ashman
Distinguished Prof.

Dr. Ashman’s research program mines the interrelationship between ecology and evolution and focuses on plant biology. It spans scales of single interacting populations to diffuse interactions within whole communities, and from evolutionary genomics to ecological genetics. Current projects in her lab are based in California, Hawaii, Oregon, Mexico and China revolve around four major foci: 1) The contribution of polyploidy to functional and genomic biodiversity; 2) Ecological and evolutionary studies of separate sexes and sex chromosomes; and 3) The influence of biotic and abiotic features on plant-pollinator interactions, and their effects on phenotypic evolution. 4) The role of plant-pollinator interactions in plant coexistence in biodiverse areas and in the face of shifting species compositions (extinctions/invasions) and climate change; 5) Urban plant ecology and the importance of pollinator-mediated interactions to plant fitness and biodiversity;  6)Pollinators as viral vectors.  Dr. Ashman is a UPitt Chancellor’s Distinguished Researcher, EO Wilson Awardee, Outstanding Mentor Awardee and has published over 175 research papers.  She has served on the Editorial boards of The American Naturalist, Ecology, and New Phytologist, as well as Secretary and Executive Council member of American Society of Naturalists, and Society for the Study of Evolution.  She is deeply committed to outreach and expanding diversity within science. 

Dr. Anne Sternberger
Postdoctoral Scholar
IMG_2562.jpeg

Dr. Sternberger received her PhD from Ohio University where she studied the environmental and genetic drivers of chasmogamous and cleistogamous flowers in violets. She is excited to be joining the Ashman Lab where she will be exploring sex chromosome evolution in the wild strawberry (Fragaria). Outside of the lab, she is passionate about outreach and inspiring children/students towards continued science education, as well as advocating equal rights for women in the science, technology, engineering, and math (STEM) disciplines.

Dr. Thomas Anneberg 
Postdoctoral Scholar

Dr. Anneberg received his PhD from Syracuse University where he studied  the effects of whole-genome duplication, or polyploidy, on the nutritional needs of plants and how their biotic interactions with mutualistic fungi are affected, making predictions based on results of individual-level performance where these early generation polyploids should become established. However, since ecological establishment is a population-level process, Thomas is now conducting postdoctoral work on the importance of abiotic and biotic interactions on the establishment of polyploid populations in collaboration with the Turcotte lab.
