Degree(s) Held:

B.S., Earth Sciences, University of Durham, UK (1998)
M.S., Palaeobiology, University of Bristrol, UK (2000)

Degree Sought:

Ph.D. in Earth Sciences

Title of Research Project:

Dinosaurs and time: Chronostratigraphic frameworks and their utility in analysis of dinosaur paleobiology, with the example of the Hell Creek Fm and regional equivalents

Advisor:

Jack Horner

Research Interests:

My research focuses in two areas: palaeontology and stratigraphy. I try to take a novel perspective on solving problems, utilising the Unified Frames of Reference (UFR) methodology encouraged at the Horner paleo lab. This involves a "total approach", taking into account the often overlooked effects of stratigraphy and ontogeny.
