Biography

I am a post-doctoral research associate in the Department of Zoology at the University of Cambridge and a research associate at the Fitzpatrick Institute for African Ornithology in Cape Town.

Research

My research addresses questions about the processes that generate, maintain and diminish diversity in the biological world. Key research themes include mimicry, parasite-host interactions, speciation, community ecology, biogeography, conservation biology and the genetics of adaptation, with a geographical focus on African biodiversity and a taxonomic emphasis on birds. 
Particularly, I am fascinated by how species interactions regulate biodiversity.When species are locked together in tight ecological interactions, evolutionary changes in the one can have consequences for the evolution of the other and vice versa. This process, “coevolution”, has been important in the generation of much of Earth’s biodiversity. Such interactions play out in varying forms ranging from parasitism through mutualism to competitive interactions over shared resources.
Parasite-host interactions are widespread in nature and generate powerful forces affecting biodiversity and structuring ecosystems. My current work focuses on brood-parasitic birds in tropical Africa and uses field experiments combined with genomics and comparative approaches to study their role in generating diversity both within and between species. My empirical research in this area can be divided into two parts, as follows.
 

i) Mimicry and speciation in the parasitic finches of Africa

For my PhD, I studied the indigobirds (genus Vidua) of Africa. Viduaare a radiation of specialised brood-parasitic finches. Host colonisation is tightly linked to speciation in Viduabecause of their capacity to imprint on hosts, with mating traits and host preferences being strongly influenced by the host environment the parasite grew up in. The hosts of the Vidua finches, the Estrildidae, possess arguably the most spectacular mouthpart ornamentation of any group of birds (see photos). These markings are important signals in mediating parent-offspring interactions. In collaboration with Professor Michael Sorenson (Boston University) and Professor Rebecca Kilner (University of Cambridge), I am studying the evolution of these mouthpart markings across the family.
Even more remarkably, the nestlings of the parasitic indigobirds and whydahs exhibit mouthpart markings that are near-perfect matches of their host’s. In collaboration with Dr Jolyon Troscianko (Exeter University) I am quantifying this similarity from an avian visual perspective. Additionally, with Professor Michael Sorenson (Boston University) and Dr Chris Balakrishnan (University of North Carolina), I am using next-generation sequencing approaches to understand the molecular basis of this mimetic convergence.
 

ii)The genetics of egg mimicry in a parasite-host co-evolutionary arms race

I am currently a BBSRC-funded post-doctoral research associate at the University of Cambridge. My current work focuses on the interactions between the brood-parasitic Cuckoo Finch (Anomalospiza imberbis) and its Tawny-flanked Prinia (Prinia subflava) hosts. Prinias have evolved incredibly diverse eggs which vary dramatically in colour and pattern between individuals. In collaboration with Professor Michael Sorenson of Boston University and Professor Claire Spottiswoode of Cambridge/University of Cape Town, I am currently investigating the genetic basis of this diversity and the consequences of this genetic architecture for the co-evolutionary trajectories in the ongoing arms race between prinias and their Cuckoo Finch parasites.
Ornithological exploration and conservation in Africa
I am involved in ornithological expeditionary work and the conservation of African birds. I am a Research Associate at the FitzPatrick Institute of African Ornithology at the University of Cape Town (http://www.fitzpatrick.uct.ac.za/fitz/staff/research/jamie).
In November 2016, I was part of an expedition to the Njesi Plateau in northern Mozambique with researchers from BINCO. Together with Sam Jones, we discovered new populations of the highly endangered Mozambican Tailorbird (Artisornis sousae) and Dapplethroat (Modulatrix orostruthus) as well as finding two species previously unrecorded from Mozambique.
