Research
 

I joined the University of Cambridge in April 2011 as a voluntary Researcher in the Behavioural Ecology Group, where I have begun working with Dr. Martin Stevens and Dr. Claire Spottiswoode on a project analysing egg colour and pattern mimicry in the Diederik cuckoo (Chrysococcyx caprius) and its host species.
 
I have a strong interest in the interdisciplinary approach to avian research and, particularly, in projects that encompass a variety of techniques to address the interactions of birds with their environment and then use this information to predict the potential impacts of threats, such as global environmental change, and to develop strategies for conservation, and I look forward to undertaking future projects in this area

Prior to Cambridge 
I completed my BSc in Biological Sciences (Zoology) at the University of Leicester. After researching literature that described the mass mortality episodes of lesser flamingo (Phoeniconaias minor) populations in and around Kenya, I conducted my Bachelors research in Kenya investigating the presence of intestinal parasites and their effects on flamingo health and mortality. I was awarded the Ede and Ravenscroft Academic Prize for Excellence to fund this.

  During my Bachelors I also participated in the Erasmus exchange programme, studying part of my degree at the University of Joensuu, Finland, where I was able to experience ecological studies, including winter ecology fieldwork, in an alternate environment.

I completed my MSc in Conservation and Biodiversity at the University of Exeter’s Cornwall campus, near Falmouth. For my Masters thesis, I investigated the brood parasitism of marsh-nesting redwing blackbirds (Agelaius phoeniceus) by brown-headed cowbirds (Molothrus ater) in Manitoba, Canada. Recent hypotheses have proposed that females may indicate their genetic quality to males by the intensity of blue-green pigment, biliverdin, deposited in the eggshell and thereby promote a higher allocation of paternal care. Since the cowbirds reproductive success depends on the crucial choice of which host to parasitise I investigated whether brood parasites exploit this signal to determine host quality and therefore use egg colour as a potential cue for host selection.
 
Since completion of the Masters I have also worked as a Research Technician in the evolutionary ecology lab at the University of Exeter (Cornwall campus) providing research support to a postdoctoral fellow, investigating the evolution of insect genitalia using Drosophila. This was a very different area to what I have previously experienced and diversified my skill set by strengthening my lab research skills.
