Academic background

I completed my MSc at the University of Hull where I focussed on understanding the characteristics that are likely to have driven the success of mammalian biological invaders such as the grey squirrel. I then moved to the University of Reading where I completed my PhD studying macro-evolutionary biology, including the evolution of mammalian body size. I then completed (as of August 2020) an Early Career Fellowship funded by the Leverhulme Trust at the University of Reading which sought to detect genotype-phenotype links across evolutionary scales. This led me to investigate the factors - both ecological and genetic - that have driven brain size, testes size, and eye shape evolution across all vertebrates. In September 2020 I will be starting on a new project seeking to understand the history of extinct hominins such as Neanderthals and Denisovans, hoping to cast a light on the evolutionary path leading to our own species.

Research areas

A unifying theme of all my research is the development, application and integration of contemporary phylogenetic statistical approaches to answering key evolutionary questions. My interests are primarily involved in macro-evolutionary biology, particularly involving large-scale evolutionary trends and patterns. I am also interested in looking at the effects of incorporating extinct and extant diversity into studies of evolutionary biology and ecology.

Expertise

  • Development and application of cutting-edge phylogenetic statistical software packages including: BayesTraits, BEAST, R
  • Bioinformatics processing of large sequences including downloading and alignment plus post-processing in other software such as PAML, HyPhy etc.
  • Programming languages for biological analysis including R, Python, Perl
  • Statistical analyses

Awards and distinctions

In 2016, I was the Environment theme PhD student researcher of the year at the University of Reading. I have been invited to teach workshops on phylogenetic comparative methods at all levels, from undergraduate to academics. Organised (along with co-organizers from the University of Cambridge) a symposium at ESEB in Turku, Finland titled "Gene-Phenotype associations across evolutionary scales".
