Thomas Halliday is a quantitative macroevolutionary palaeobiologist studying the evolution of Late Cretaceous and Palaeogene vertebrates. In particular, he is interested in the diversification of placental mammals, global patterns of faunal similarity, and the methods used to answer big questions of relationships, timing, and diversity.


  • MA in Natural Sciences (Zoology) – Cambridge
  • MSc in Palaeobiology – Bristol
  • PhD - UCL


Dr Halliday’s PhD was completed in 2015 at UCL, researching the relationships among several enigmatic families of mammal that existed in the Paleocene – the ten million year period immediately following the end-Cretaceous mass extinction. He followed this with a postdoctoral research position, also at UCL, incorporating genomic data to address conflict between morphological and molecular data, before being awarded a Leverhulme Early Career Fellowship to be held at Birmingham from 2017, studying the effects of different forms of bias from the fossil record on the reconstruction of the tree of life.

Postgraduate supervision

Dr Halliday does not currently have any students, and has no advertised projects. Contact him if you want to discuss future projects.
