Research
I explore how plants can be used to reconstruct
ancient environments, and the (paleo-) physiological underpinnings behind these plant-environment relationships. Recent and current projects include
the reconstruction of Eocene (~40 Myrs ago) atmospheric carbon dioxide levels from the stomatal distributions in plant leaves, and the development of
mechanistically-grounded proxies for climate and leaf ecology from the size and shape of fossil leaves. I also compile ancient carbon dioxide
records and investigate the strength of carbon dioxide-temperature coupling over multi-million-year timescales.

I am looking for enthusiastic students (both undergraduate and Masters) to carry out original research on these topics!
