About

I am a micropalaeontologist and hold a joint position with the British Geological Survey. I study changes in communities over space and time.  Cenozoic palynology (pollen, spores and dinoflagellate cysts) is my core expertise with emphasis on biostratigraphy, palaeoecology and geographic distribution. In particular, the response of vegetation to global climate perturbations in the early Palaeogene of North America and Europe has formed the core of my research and the source for my varied research questions.

Qualifications

  • PhD Cenozoic palynology - University of Sheffield
  • MPhil Biological Sciences - University of Cambridge
  • BSc Geography and Geology - Keele University

I have worked as a research fellow at the University of Sheffield (1998-1999), University College Cork (1999-2002), and finally as a Visiting Scientist at The National Museum of Natural History, Smithsonian Institution (2002-2004). I am still currently a Research Associate of the Department of Paleobiology, Smithsonian Institution (2004- present)

Current/recent research

Organic provenance and biostratigraphy

Palynomorphs such as pollen, spores and dinoflagellate cysts (dinocysts) are highly important for helping to determine depositional environments and age of sediments in the past. I sailed with IODP Expedition 337 (Deep coalbed biosphere off Shimokita) to northeast Japan as team leader for biostratigraphy.

Microfossil work on this expedition helped determine the age model based on Cenozoic pollen and spores (Oligocene-Miocene), and the environment based on palynofacies. I have also undertaken provenance studies and help derive age-models of marine sediments from the Wilcox Group (Paleocene-early Eocene) in the Gulf of Mexico (GoM).

This industrially-sponsored work helps determine the likely source areas of sediments in different parts of the economically-important GoM hydrocarbon fields: Palynomorphs are silt-sized sedimentary particles and can be transported effectively over great distances in rivers, through delta systems and then onto the continental shelf. With the British Geological Survey I work within groups undertaking shale gas research.

Palaeogene climate change and plant responses 

Long-standing research has centred on biological responses to the Paleocene-Eocene Thermal Maximum (PETM). This rapid interval of global warming of c. 6°C at ≈55.8 Ma is marked by perturbations in climate and environment in both the marine and terrestrial realms from the poles to the equator.

This work has been undertaken from North America in the Bighorn Basin (Wyoming), Williston Basin (North Dakota), Ellesmere Island (Nunavat), and both the eastern and western Gulf of Mexico (Texas, Mississippi and Alabama). We recently cored sections of the Bighorn Basin because it contains the thickest and best terrestrial exposures of late Paleocene – early Eocene rocks globally.

Participation in the active BBCP (Bighorn Basin Coring Project) examines vegetation changes through the PETM using pollen and spores as a proxy for plants and is in collaboration with a large US-led consortium of universities and research institutes. This research is funded by NSF. A recent project funded by the EU Framework 7 (PEX: Testing for plant extinction across the Paleocene-Eocene boundary) databased all occurrences of late Paleocene- early Eocene pollen and spores records from North America and Europe in order to understand how plant geographic distributions change through climate perturbations in the early Paleogene. With the British Geological Survey I lead a project focused on PETM climate dynamics and biotic response from the North Sea.

Plant community dynamics in deep-time

Our research from the PETM feeds into questions relating to how biodiversity is partitioned and distributed in globally warm periods of Earth history. In addition to understanding how plants respond to climate change, my research, including collaborations with postgraduate students, seeks to understand how plants are distributed over time and geographic space on scales that exceed those of the Quaternary or Holocene time domain that forms the basis for our understanding of plant community dynamics.

This research is from the USA (Paleocene, GoM), Shanwang in China (Middle Miocene) and now from the western Amazon Basin (Miocene-Pliocene). I have also studied in the past outcrops from Oregon (Late Eocene – Oligocene) and early Eocene of the Canadian Arctic. Our research has been funded by multiple sources including the Nuffield Foundation, Mellon-Carnegie Foundation, NSF SYNTHESYS, and CAPES.

Other activities

I am currently a Director-at-large for AASP The Palynological Society and have previously held the position the Secretary for the Linnean Society Palynology Specialist Group (2006-12). I have also been a council member for the Palaeontographical Society and was co-opted onto Council for the Palaeontological Association as the meeting organiser for 2009.
