Supervisors: Dr. Duncan McIlroy

Ph.D. Thesis Title: The role of physical and biogenic sea-bed reworking as a prime modifier of late diagenetic processes in shallow-marine mudstones. I am interested to develop an understanding on how non-steady diagenesis controls organic matter quality in ancient type examples of mud-dominated, high-energy systems such as muddy coastlines, deltas, and fine-grained turbidites in the UK (Yorkshire Coast), Canada (eastern Newfoundland) and Mexico (Baja California).

I am particularly interested to understand how animals manipulate naturally occurring diagenetic reactions and how these reaction products (i.e., pre- and post-compaction cements, clay minerals and organic materials) affect reservoir quality in conventional and unconventional hydrocarbon reservoir facies.
