Research interests

Phylogeny, diversification and trait evolution

My research focuses on modelling the diversification of species and traits at a macroevolutionary scale. I am particularly interested in how we can use information on the phylogenetic relationships among species to infer how present day biodiversity has arisen over time and ask:

  • How and why do lineages and traits diversify?
  • What are the consequences of varying tempo and mode of lineage and trait evolution for temporal and spatial patterns of diversity?

My research group works closely with the Natural History Museum and we have collected extensive data bill shapes and plumage colours from all extant bird species (~10,000 species) using museum study skins (mainly the NHM at Tring and also the University of Manchester Museum).

You can get involved with this ERC-funded project with our Bird bill citizen science project at markmybird.org and with plumage evolution at projectplumage.org.

Teaching activities

My research interests are reflected in my teaching. I currently lecture on biogeography and macroecology in APS123 (Population and Community Ecology), phylogenies and diversification in APS220 (Evolutionary Biology) and APS342 (Evolutionary Ecology). At level 4, I supervise Research Projects (APS406) that typically address core themes of the lab: how and why do species and their traits diversify? Recent projects have asked how occupancy of isolated islands influences divergence in bill morphology in finches, what factors predict the diversity of colour among bird species, and whether egg laying (oviparity) versus live-bearing (viviparity) determines the rate of speciation in snakes.

Starting in 2019, I will lead a new masters-level module on Biodiversity in Space and Time as part of our new MSc courses in Biological Sciences and Biodiversity and Conservation.
