Biography

2016 - pres: Lecturer in Global Change Modelling at School of Earth and Environment

2011 - 2016: Leverhulme Early Career Fellow - SEE, University of Leeds

2009 - 2011: British Geological Survey PDRA

2008 - 2009: Higher Scientific Officer - British Antarctic Survey

2004 - 2008: BAS / University of Bristol PhD Student

I spent 5 years at BAS, first doing a PhD producing the first physical models of mid-Pliocene (~3 million years ago) Greenland and East Antarctic Ice Sheets, then as a post-doc adding higher-order physics into BASISM. For the following two years I was employed by the British Geological Survey (BGS), primarily modelling the Pliocene climate on a project entitled 'Understanding the Pliocene and Anthropocene - linking the past to the future'.

Having initially moved to the School of Earth and Environment, University of Leeds (UoL) to undertake a Leverhulme Early Career Fellowship entitled, 'Can state of the art models reproduce climates of the past?', and then working as a University Research Fellowship. I am now a Lecturer in Global Change Modelling and have a number of funded projects which have been completed in recent years or are ongoing.


Present and Past Research Projects

2019 - 2024: ERC Starting Grant
              CLaSS - Climate, Landscape, Settlement and Society: Exploring Human-                      Environment Interaction in the Ancient Near East

The CLaSS Project is collaboration between Durham University, Eberhard Karls Universität Tübingen, and University of Leeds, led by Dr. Dan Lawrence and funded by an ERC Starting Grant. The project investigates the relationship between climate fluctuations and the emergence of complex social and political formations over the last 8000 years across the Fertile Crescent region of the Near East, including: Lebanon, Turkey, Syria, Iraq and Iran.


2017 - 2021: NERC Biosphere Evolution, Transitions & Resilience Project
                    Ecosystem resilience and recovery from the Permo-Triassic crisis

The Permo-Triassic boundary saw one of the greatest mass extinctions in all of Earth history. Rapid climate change in response to huge volcanic emissions of carbon dioxide has been implicated as the primary driver of the mass extinction. This project will compare the response of terrestrial and marine ecosystems and quantify the climatic drivers of both the mass extinction and the extended recovery period in the early Triassic.


2015 - 2018: NSFC Project (with Chinese Academy of Science)
                    Impacts of the Paratethys on environmental evolution in the Tarim Basin:                       Geological observations and numerical simulation

Marine retreats and mountain uplift in the Himalayan and Paratethys regions during the Cenozoic have resulted in the increasing aridification of Central Asia. This project will produce new records from the Tarim Basin (Taklamakin Desert) examining the retreat of the Paratethys Sea and associated climate changes. This will compliment new climate model simulations of the Oligocene climate of the region.


2015 - 2016: UoL International Research Collaboration Award
                    The climatic drivers of biodiversity over the last million years

Modern patterns of biodiversity are dependent on the biogeographic history of the organisms in question. Within a species this is strongly controlled by the recent climate history of the ecosystems and regions were the species lives. This project will produce pilot data to test the importance of climate variability and precipitation extremes in the biodiversity of South American forest ecosystems.


2011 - 2014: Leverhulme Early Career Fellowship
                    Can state of the art models reproduce climates of the past?

The latest climate models are well tested against historical climate records. However, they have not been evaluated against much larger climate changes, such as those predicted for the near future. This project will simulate, using the latest versions of the UK Met Office climate model, three well documented periods of the recent geological past. These are the Last Glacial Maximum, a particularly cold climate, the moderatel warmer-than-modern last interglacial and the significantly warmer mid-Pliocene. This will enable the skill of this model in simulating large climate changes to be evaluated and comparisons with other climate models from around the world.


2010 - 2012: NERC UK Integrated Ocean Drilling Programme
                    Instability of the East Antarctic Ice Sheet during the Pliocene warmth?

The East Antarctic Ice Sheet has long been seen as a stable ice mass, but recent evidence has suggested that marine portions of the ice sheet may have collapsed during the moderately warmer climates of the Pliocene. This project will produce new records from IODP Site 1165 of the icebergs coming off the vulnerable sectors of the ice sheet and employ iceberg models to understand their transport.


2009 - 2011: British Geological Survey PDRA
               Understanding the Pliocene and Anthropocene - Linking the Past to the Future

The Pliocene has often be used as a palaeoclimatic anologue for future climate change and was included in the most recent IPCC report as an 'accessible example of a world that is similar in many respects to what models estimate could be the Earth of the late 21st century'. Through UK Met Office GCM modelling of both the Pliocene and future climate we aim to test this principal and further our understanding of the workings of climate in warmer than modern temperatures.


2008 - 2009: Higher Scientific Officer - British Antarctic Survey
                    Data Assimilation and Higher-order Physics in BASISM

For 18 months I worked with Rob Arthern and Richard Hindmarsh on the BAS ice sheet model (BASISM). The ultimate goal of the project was to incorporate the large number of observations of the present-day ice sheet into predictions of its future evolution. These techniques have been previously used in numerical weather and climate predictions (climateprediction.net). This project is ongoing and my contribution was largely in the testing and development of higher-order physics within BASISM.


2004 - 2008: BAS / University of Bristol PhD Student
                    Modelling Earth's Cryosphere during Peak Pliocene Warmth

My PhD was undertaken at BAS, supervised by Alan Haywood (BAS/Leeds), Richard Hindmarsh (BAS) and Paul Valdes (Bristol). The mid-Pliocene (3.3 - 3 million years ago) was the last time in Earth History when temperatures were significant warmer than modern for a sustained period of geological time. Modelling shows that temperatures were similar to those predicted for 2100AD. The behaviour of the ice sheets and their climatic feedbacks are one of the greatest uncertainties in the predictions of future climate change and the behaviour in the Pliocene is also highly disputed. By taking existing models of the Pliocene climate and using them to drive BASISM, I was able to produce the first physically-based reconstructions of the Pliocene ice sheets, which have been incorporated in the latest PRISM3 mid-Pliocene palaeoenvironmental reconstruction
