I am a Research Associate in the Behavioural Ecology Research Group. I completed my DPhil in December 2012, supervised by Prof. Alex Kacelnik.
Together with colleagues from the University of Buenos Aires' Laboratorio de Ecologia y Comportamiento Animal, I study cowbirds (Molothurus sp.), a fascinating group of birds found in the Americas. 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. My research spans a number of aspects of the evolution and maintenance of South American cowbird species, 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 parasites, and provisioning strategies and defense portfolios in hosts.
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. In 2014 I began a University of Sydney Postdoctoral Fellowship, investigating brood parasitism and other behaviours in social bees in the Behaviour and Genetics of Social Insects Laboratory, School of Biological Sciences, University of Sydney.
