Research Interests

Description Of Research Interests

My main research interests are: 1) PALYNOLOGY - the use of palynomorphs in Palaeozoic rocks to determine their age, depositional environment and palaeogeographic setting. 2) ORGANIC PETROLOGY - interpretation of thermal histories of rocks based on studies of microscopic plant debris and other organic particles. Current areas of interest include Ireland, Bolivia, Portugal, Jordan, Saudi Arabia and the USA.
