Academic Interests

Though I am not necessarily new at CEES, I am new as a PhD candidate. I recently completed my masters degree on the role of sex-linkage and mito-nuclear incompatibilities in the reproductive isolation of a homoploid hybrid (the Italian sparrow). This was under the supervision of Glenn-Peter Sætre, Richard Bailey and Jo Hermansen. My research will continue in the sparrow group as I will study timing as a reproductive barrier. For my PhD research, I plan to use the sparrow system to investigate genes involved in timing ie.‘clock genes’ and their role in hybrid speciation.
