My broad career path was settled when I was just a toddler… While other children played cops and robbers, I upended rocks, adamant that I would become an entomologist and not a policeman. But my world was upended in my second year of university when the then-“Young Guns” of South African Botany (Jeremy Midgley, William Bond and Peter Linder) hijacked my mind with plants, a kingdom which had previously escaped my attention. Their brand of hypothesis-driven field science excited me and profoundly influenced how I teach and conduct research. They taught me to be critical, creative and questioning, and demonstrated how science can be a source of mental and physical adventure. My first love is the field, observing organisms in their natural environments, inventing hypotheses and testing them by means of experiments. I am driven by the desire to understand why organisms look the way they do, and how they are adapted to their biotic and abiotic environments. Studying pollination biology, herbivory and seed dispersal, I get to delve into the interactions between plants, insects and other animals, daily exploring a world even more intricate and complex than the one imagined by my three-year-old self.

Without animals, plants would look quite different. For example, flowers would not be designed to catch the eye and the world would be a less colourful place. Animals too, would not exist as we know them; birds would not have long beaks and tongues to sip nectar and many moths, flies and butterflies would also have very different feeding mouthparts. I am interested in evolutionary ecology and the adaptations of plants and animals to their environments. Much of my previous and current research focusses on geographic variability in the biotic and abiotic environment, which has enabled me to study how the evolutionary paths of plants and animals are shaped by each other and their abiotic habitats. In particular, geographically variable interactions often result in geographic divergence of morphology which can ultimately result in speciation events. More recently we have developed a technique to mark pollen grains with fluorescent particles, enabling us to follow the fates of pollen in time and space. This has opened up exciting, new research possibilities allowing us to explore the ways in which components of male fitness (pollen deposition) drive floral evolution.
