Dr Tom Stubbs is an evolutionary biologist interested in biodiversity and morphology. Tom first graduated from the University of Sheffield (BSc Environmental Science), before moving to the University of Bristol for postgraduate studies in evolution and palaeobiology (MSc, PhD). Since 2015, Tom held two postdoctoral research positions in Bristol and was promoted to a senior postdoctoral researcher in 2020. Tom then joined The Open University as a Lecturer in Biology in 2023.
Tom’s research uses the fossil record and living animals to explore the uneven distribution of biodiversity across the Tree of Life and through geological time. Tom works on crocodiles, marine reptiles, dinosaurs, birds, lizards and snakes, mammals, fish, insects, and other invertebrates, to understand how diverse groups rise and fall, and how new evolutionary innovations emerge.
The key theme underlying all Tom’s research is the study of morphological evolution. Tom researches the evolution of morphological variety (disparity) over large geological timescales. This includes dynamics during evolutionary radiations, the evolution of new ecological innovations, and responses to extinction events.
Currently, Tom is exploring large-scale patterns of morphological change inclusively across all tetrapod animals (amphibians, reptiles, birds, mammals), covering both living (~580 families) and extinct (>1000 families) forms in a universal framework. Tom has also recently initiated projects on the evolution of insect morphology.
Prospective research students
Tom can supervise postgraduate research projects linked to his interests as part of the new Interdisciplinary Life and Environmental Science Landscape Award (ILESLA) doctoral training programme.
Tom's work is alligned with the following ILESLA research themes:
1. Rules of Life - evolutionary biology and integrative biology
2. Biodiversity and Sustainability - systematics
3. Transformative Technologies - computational biology
Potential PhD subject areas broadly include:
Specific projects can include:
These subject areas and projects could feature any animal or plant group, although Tom is particularly interested in living and extinct vertebrate animals, and is starting new projects on insect evolution and biodiversity.
