Dr. Alana Alexander

Alana Alexander received her PhD from Oregon State University (USA). Her research uses population genomic, phylogenomic, ecological, and biogeographic data, as well as genomic and computational approaches, to test hypotheses about the processes leading to observed patterns of genetic diversity within and among populations.

In the Gemmell lab Alana offers bioinformatics research assistance on projects, as well as working on a number of additional projects, such as using genomes to investigate the demographic history and evolution of the Hector's and Maui dolphin (Cephalorhynchus hectori), ddRADseq to investigate historical population demography of the North Pacific humpback whale (Megaptera novaeangliae) in response to whaling and climate change, and characterizing why and how the black-capped and Carolina chickadee (Poecile spp.) hybrid zone is moving in the southeastern United States.

Her work often focuses on cetaceans as many were hunted (or subject to bycatch) at an industrial scale for meat and oil well into the late 20th century, dramatically reducing population sizes in many species, often to the brink of extinction. This makes them a particularly compelling group for inferring evolutionary and ecological processes leading to observed patterns of genetic differentiation and diversity.
