I am a DPhil candidate and Clarendon Scholar here at Oxford's Zoology Department, supervised by Prof. Alex Kacelnik. I work with a unique group of birds found in the Americas and known commonly as cowbirds (Molothurus sp.). Cowbirds are brood parasites and do not rear their own young, instead dumping their eggs in the nests of other (host) species which then raise the young cowbirds at their own expense, generally alongside some of their own offspring. My research spans a number of aspects of the evolution and maintenance of parasitism in these systems, with the aim of shedding light on how apparent maladaptive behaviours persist in both parasites and hosts. This includes work on begging behaviours and virulent behaviours in cowbirds, and provisioning strategies and defense portfolios in hosts.
Much of my year is spent in Oxford, but during the southern summers I am at my fieldsite in Argentina (Reserva El Destino, Fundacion Elsa Shaw de Pearson). Here occur two species of cowbird, shiny cowbirds ((M. bonariensis) and screaming cowbirds (M. rufoaxillaris) and also many host species. Here too, I have the good fortune to collaborate with researchers from the University of Buenos Aires’s Laboratorio de Ecología y Comportamiento Animal (Departmento de Ecología, Genétic y Evolución; Prof. Juan Reboreda) and to enjoy the remarkable birdlife and other natural wonders of Argentina.
I am broadly interested in the field of Animal Behaviour, including the ecology, genetics and evolution of animal behaviours, and I have a fascination with creatures of all kinds. I have previously worked with bees and termites during two rewarding years in the Behaviour and Genetics of Social Insects Laboratory at the University of Sydney, Australia (School of Biological Sciences; Prof. Ben Oldroyd & Dr. Madeleine Beekman). Prior to this I completed my Bachelor of Science at the University of Sydney. I also have a Bachelor of Arts (Literature), University of Sydney.
