Principal Investigator

Diana Rennison

Diana is an Assistant Professor in the Division of Biological Sciences at the University of California San Diego. Diana completed her M.Sc. at the University of Victoria in 2010, where she worked on opsin gene duplication and divergence in Poeciliid fish. In 2016 she completed her Ph.D at the University of British Columbia, where she studied the genetic basis of adaptation in the threespine stickleback to predation and other sources of divergent selection. For her postdoctoral work she took up a Marie Sklodowska-Curie Fellowship at the University of Bern; during this time Diana studied parallel genomic differentiation and genetic sources of evolutionary constraint.

Laura Varey – Laura is an M.Sc. student in the group. She is looking at differential selection on lateral plates.

Postdoctoral Fellows

Andreas Härer

Andi joined the lab as a PostDoc in February 2020. He finished his Ph.D. at the University of Konstanz, Germany in 2018, followed by a one-year PostDoc. He mainly studied the visual system and gut microbiota of Neotropical cichlids to better understand how organisms adapt to different environments. Particularly, he is interested in how much of the phenotypic variation is environmentally induced (phenotypic plasticity) or genetically determined (adaptive evolution) and to what extent phenotypic change in response to shared environmental conditions can be predicted (parallel evolution). At UCSD, Andi will be working on eco-evolution projects involving the gut microbiota and visual system of threespine stickleback, both by studying natural populations and by performing controlled experiments in the lab.
