Sophie Archambeault

Professor Archambeault is interested in how populations of organisms evolve and adapt to new environments. Her research focuses on identifying the genetic variants (mutations) that drive evolution, characterizing how these variants affect gene function, linking these variants to changes in development and phenotype, and ultimately understanding the selection pressures that favor these evolutionary changes. Professor Archambeault uses the threespine stickleback, a native Bay Area fish, to address these questions.
