Key Research Interests

My research addresses the highly topical and controversial problem of the origin and early evolution of land plants. My research integrates evidence from both fossil and living plants. Fossil evidence is in the form of early land plant megafossils and dispersed microfossils—spores and fragments. I am currently working on material from China, Oman, Saudi Arabia, Scotland, Kazakhstan and Spitsbergen. I study living plants in order to interpret the earliest land plant fossils through, specifically:

  • cladistic analyses of evolutionary relationships
  • molecular clock analyses of evolutionary divergence times
  • analysis of physiological adaptations required for plants to invade the land (particularly Evo-Devo studies on the molecular genetics of spore/pollen wall development).

I am also exploring the impact of the invasion of the land by plants on global change. This has led to research into developing a novel (and currently only) proxy for past UV-B radiation. In recent years I have also extended my research back in time to examine a previously neglected research area considering the ‘algal scum’ that inhabited the land before it was invaded by plants.

Teaching

I teach across all levels within APS. He is APS Level 3 tutor. In 2008 he received the Departmental Teacher of Year award.

At Level 1 I am module coordinator for APS121 (Evolution) and APS122 (Biodiversity).

At Level 2 I am module coordinator for APS269 (Palaeobiology). This module aims to instil within biology undergraduates a basic understanding of palaeontological principles—why understanding past life enhances our understanding of the living world.

At Level 3 I am module coordinator for APS341 (Evolution of Terrestrial Ecosystems). This module explores my personal research specialism and provides an up to date and in depth exploration of how terrestrial ecosystems have evolved through time and the nature of the scientific enquiry that enables us to understand this.

My Level 3 Projects (APS330) generally involve a palaeobiological investigation of fossils (usually plant fossils) that are collected and prepared by the students. These studies may concern analysis of evolutionary trends, palaeoecological investigation or palaeoenvironmental reconstruction. My Level 3 Dissertations (APS331) cover any topical area of palaeobiology (human evolution, dinosaur palaeobiology, mass extinctions etc.).

Level 4 Projects (APS406) cover aspects of palaeobiology that are currently interesting me. They have included investigation of sexual dimorphism in stegosaur dinosaurs, reconstruction of Cretaceous palaeogeography, analysis of Silurian lake palaeoecology, assessing the impact of the end Devonian mass extinction on various organisms etc.
