The world is complex and ever-changing. For life to survive and thrive in spite of this variability, organisms must be able to obtain accurate and timely information about their surroundings. My primary research interests center on the evolution and ecology of sensory systems.

I am currently a postdoctoral research position in the Department of Evolutionary Biology at the Max Planck Institute for Developmental Biology (in Tübingen, Germany), where I am studying aspects of pheromone signaling and reception in Pristionchus nematodes under the supervision of Dr Ralf Sommer. My PhD research focused on visual pigments, the light-sensitive proteins found in rod and cone photoreceptor cells, and was carried out under the supervision of Dr Belinda Chang and Dr Helen Rodd.
