Hester completed her PhD in 2016 at the University of Bern where she worked on characterizing the molecular basis of adaptation to pollinators in Petunia. In particular, she focused on alterations in anthocyanin pigments and the UV-absorbing pigments, flavonols. Hester is interested in the molecular and biochemical changes that underpin the evolution of different phenotypes. She is intrigued by how entire genetic networks can evolve to produce novel, specialized compounds. Her work in the Brockington lab will focus on understanding the molecular and biochemical basis of the emergence of the betalain pigments. She is funded by a Swiss National Science Foundation post-doctoral fellowship.
