Dr. Andreanna J. Welch (PI)
I am broadly interested in using molecular and genomic techniques to learn about and conserve the diversity of life around us. If it's got DNA, then I'm interested! Though, I do have a special fondness for birds, particularly seabirds, as well as marine mammals. I am also passionate about supporting early career researchers and increasing the diversity of scientists in Ecology and Evolution.
Alma Liss S. Quiñones (Post Doctoral Research Associate)
Alma Liss is working on a European Cocoa Association funded project investigating the identity of cocoa pollinators in Ghana using flower environmental DNA metabarcoding. She recently completed her PhD in the lab as well, during which she worked on our biodiversity and ecosystem services project. She developed the eDNA flower metabarcoding methods to identify cocoa pollinators in Cameroon, investigated bird and bat species that consume cocoa pests, and investigated how cocoa farmers understand and view ecosystem service provision.
Beth Jetson (Ph.D. Student)
Beth is working closely with Heather Ferguson at University of Glasgow and Emmanuel Kaindoa and Herieth Mahenge at Ifakara Health Institute in Tanzania to use DNA metabarcoding methods to detect Anopheles mosquito vector species in the environment.

She is completing her Ph.D. studies at Imperial College London under the supervision of Joe Tobias.
Ned Sanderson (Research MSc Student)
Ned's project examines the spatial pattern of diffuse pollution from the landscape – the small amount of sediment and nutrients that are eroded and accumulate in the rivers – with the aim of identifying where the key sources of the pollutants are. He is using EDNA as a measure of ecological community composition and explore how that can be related to ecosystem health and hence where the pollution is degrading it.
Alumni
Dr. Luke L. Powell (Research Fellow)
Luke and I have been working in close collaboration to characterize species interactions in Central African cacao plantations. We use mist-netting for birds and bats, biodiversty surveys, and sophisticated diet DNA metabarcoding (in which prey of hundreds of birds and bats can be simultaneously identified) to construct novel Bayesian food web models with the goal of identifying and developing management plans for keystone species providing ecosystem services to farmers. Luke now has a position at CIBIO-InBIO, Universidade do Porto in Portugal.
