Ashman Lab members - a community of scholar-educators
Dr. Tia-Lynn Ashman
Dr. Anne Stenberger
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 and has published over 150 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.
Vero is a 1st year graduate student. She received her bachelor's from Wake Forest. She is exploring the effects of herbiced drift on plant, microbe and pollinator communities with and interest in eco-evo dynamics .
Liz graduated from the University of Pittsburgh in 2017 with a B.S. in Biology.
Madison is a Biology major and is studying plant pollinator interactions
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. Sergio Ramos
PEEP Postdoctoral Fellow
Dr. Ramos received his PhD from the University of Zurich. In collaboration with the Turcotte and Ashman labs Serch will be examining the effects of inter- and intraspecific genetic variation on the structure of mutualist and antagonist interaction networks and on the patterns of natural selection.
Nevin is a 2nd year graduate student. He received his bachelor's from Humboldt State University and his MS from SFSU. He is exploring drivers of pollen transfer diversity in pollinators and the effect of metal accumulation on floral microbes and plant-pollinator interactions.
Andrea is a 4th year graduate student. She received her bachelor's from St. Mary's College where she studied plasticity in floral volatile. She is exploring pollinators as vectors of viruses and urbanization's effects on pollination networks.
Rebecca is a UPItt Alumna. After completing her bachelors degree at she is working with the Ashman lab to develop a biology curriculum based on the floral microbiome prior to embarking on graduate school.
Steffani is a Biology major and is studying flower bacterial community composition.
