Fully Funded PhD projects
I'm currently advertising two fully funded PhD projects, to start October 2020:
OU-18: Changes to the global carbon cycle during middle Miocene Climate Transition co-supervised with Prof. Angela Coe, applying advanced organic geochemical techniques to samples from the classic Monterey Formation (California, USA) to study this critical interval in Earth's climate transition from the "greenhouse" of the early Cenozoic to the "icehouse" of today.
And:
OU12: Indian Summer Monsoon variability in response to Pliocene climate led by Dr Pallavi Anand with Dr Clara Bolton (CERGE) generating the first high-resolution record of Indian monsoon runoff in the Pliocene using multi-proxy geochemical and micropalaeontological techniques. The Indian monsoon effects over a billion people, and by studying this fascinating climate system in the warm Pliocene we will inform future projections of how the system may operate in our warm future.
These PhDs attract a stipend of £15,009 per annum through funding from the Natural Environment Research Council (NERC). This funding is limited to UK/EU students who have been ordinarily resident in the UK or EEA for at least the last 3 years.

Biography
I’m a Lecturer in Earth Sciences in the School of Environment, Earth and Ecosystem Sciences at The Open University. My research concentrates on exploring the links between the Earth’s carbon cycle and climate on Cenozoic timescales, and I deploy a range of tools including organic geochemistry, foraminiferal geochemistry and General Circulation Models.
I graduated from Jesus College, University of Oxford with an MEarthSci (Hons) in Earth Sciences in 2005. Whilst there I worked on the prospects of developing a sea surface temperature proxy using stable strontium isotopes in coccolithophores calcite analysed by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The project was supervised by Dr Ros Rickaby.
In 2005 I moved to the school of Earth and Ocean Sciences, Cardiff University to conduct my doctoral research into middle Miocene climate dynamics, supervised by Dr Carrie Lear (Cardiff) and Prof Rich Pancost (Bristol). Using coupled organic and inorganic climate proxies, I constructed high resolution records of atmospheric pCO2 (alkenone and boron isotopes) and sea surface temperatures (foraminifera Mg/Ca and alkenone unsaturation indices). These proxy records, coupled with carbon system models and carbonate stable isotopes, allowed me insight into carbon cycle dynamics at a critical interval of major ice sheet growth in Antarctica. My PhD was awarded in 2010.
Following my PhD I moved to the Organic Geochemistry Unit in the School of Chemistry to work with Prof. Rich Pancost as a postdoc. I've worked on a number of grants with Rich, developing records climate and environmental change at various times through the Cenozoic, working mainly with hyphenated techniques (GC-MS, LC-MS, GC-C-IRMS).
In October 2011 I moved to the department of Earth Sciences for a stint as a lecturer, before returning to the OGU to take up a post as a Senior Research Associate in March 2013. Research during this time focussed on terrestrial methane cycling during Paleogene greenhouse climates, which involved collaborative work using the Unified Model with colleagues from the BRIDGE group (Paul Valdes) alongside organic geochemical approaches.
Much of my research focusses on sediments recovered from the ocean floor, and in autumn 2013 I took a short break from the OGU to participate in the TROPICS research expedition aboard the RRS James Cook (pictured above). Details of the expedition can be found here: http://tropics.blogs.ilrt.org/.
I moved to School of Environment, Earth and Ecosystem Sciences at The Open University in March 2016.
I went back to sea again in the summer of 2017, this time aboard the RRS Discovery to the Labrador Sea to participate in the European Research Council funded ICY-LAB project lead by Dr Kate Hendry from the University of Bristol. The expedition aims to increase our understanding of nutrient supply in the oceans. More details can be found on the project website: https://icylab.wordpress.com/.

Research interests
I study ancient climates using molecular fossils. When an organism dies, often components of the organic remains are preserved in sediments. By analysing molecules characteristic of particular organisms or environmental conditions (“biomarkers”) we can reconstruct ancient environmental parameters. My research primarily uses organic geochemical proxies analysed by GC, GC-MS, LC-MS and GC-C-IRMS to reconstruct sea surface temperatures (TEX86 and UK'37) and atmospheric pCO2 (alkenone δ13C) along with other key indicators of past climates.
I us a multi-proxy approach and so also utilise more ‘traditional’ inorganic proxies, based on the skeletal remains, such as planktic foraminiferal Mg/Ca, δ13C and δ18O. My research focuses on key periods in the Cenozoic (the last 66 million years) including the middle Miocene Climate Transition (when large ice sheets first appeared on East Antarctica), the warm Pliocene (one of the best partial analogues for future anthropogenic warmth) and the PETM (Paleocene-Eocene Thermal Maximum).
The fidelity of our proxy methods for reconstructing ancient climate change is essential if we are to use that understanding to help predict the future, so a lot of my current efforts concentrate on thoroughly testing our proxies.
New capabilities
I'm currently setting up new (to the OU) processes in my labs and am interested in finding new collaborators! We have fantastic facilities and capabilities to run foraminiferal trace metal and organic geochemical analyses including lipid analyses by GC, GC-MS and GC-C-IRMS and GDGT analyses by HPLC-MS. If you have exciting ideas and samples get in touch!

Science: Concepts and Practice (S112)
I'm a core author and, with Dan Berwick, co-chair for presentation on the first year module Science: Concepts and Practice (S112).The module provides a solid toolbox of knowledge, understanding, and skills for science students across the university. I wrote material on environmental change, living in a changing climate, and contributing material for other Earth science sections of the module.
Earth Processes (S309)
I'm a guest author on the level three module Earth Processes (S309), and wrote sections on the Intergovernmental Panel on Climate Change (IPCC) for the science in society module in 2016. The course is one of the first OU courses to use direct authoring on the OpenEdx platform.
Terrestrial Ecosystems (S397)
I'm on the module team for the level three module Terrestrial Ecosystems (S397). I helped to refresh what has been a very popular module and make it fit for online delivery.
