Boris joined the lab in 2018 as a post-doctoral research assistant funded by NERC. He obtained his PhD from the University of Toulouse (France) in 2015 working with Prof. Christophe Thébaud and Dr. Borja Milá. He then worked with Dr. Anne Charmantier and Dr. Céline Teplistky as a post-doctoral research associate at the Center for Functional and Evolutionary Ecology, Montpellier, France.

Research overview

Boris is mainly interested in understanding how ecological and evolutionary processes combine to generate and maintain biodiversity.
During his PhD, he worked on a stunning bird species complex endemic to Reunion island, the Mascarene white-eye (Zosterops borbonicus), which stands as one of the rare cases of within-island diversification in birds. He explored the role of selective and historical factors in this diversification and explored the dynamics of hybrid zones in different environmental contexts. During his first postdoctoral project, he explored how the genetic architecture of wild bird populations is shaped by natural selection, and how both genetic architecture and natural selection interact to influence evolutionary trajectories. He investigated these questions using various quantitative genetic tools on several blue tit (Cyanistes caereleus) populations that have been monitored for up to 40 years.
His current project aims at understanding the ecological and population genetic processes that generate and maintain floral variation and lead to incipient speciation in the South African daisy Gorteria diffusa. To do so, he combines environmental, phenotypic and molecular data to investigate how variation is affected by natural selection resulting from ecological context and how such variation is maintained when varieties meet.
