I am a climate scientist currently working as a Research Fellow in the School of Earth and Environment at the University of Leeds. Through my work I seek to better understand the nature and timing of Earth system responses to past climate oscillations. More specifically, through my work I aim to improve the dating of sediment records, allowing us to accurately correlate records of past climate change. With well-dated records, we can better understand the spatial variability in when, and how quickly, the cryosphere, ocean, atmosphere, and ecosystems respond to climate change. We can use this information to test and improve our climate models, constrain long-term sea level projections, and inform conservation efforts.

Employment

University of Leeds

Research Fellow in Quaternary Palynology

I am currently employed as a Postdoctoral Research Fellow on the ERC funded RISeR project, which aims to better constrain the potential impacts of long-term ice sheet melt by examining marine sediment seqences from the warmer-than-present Last Interglacial (ca. 125,000 years ago).

At present, I am building chronologies for the sediments preserved offshore in the North Sea to aid reconstructions of the rates of sea-level change experienced in the region, particularly their relative timing to changes observed in the terrestrial record.

PhD Geography

Title: Resolving abrupt palaeoenvironmental changes in a lake sediment sequence from Ioannina, northwest Greece

My PhD thesis sought to reconstruct vegetation responses to abrupt climate change using lake sediments from Ioannina, northwest Greece for the period 45-40 ka BP. This involved production of a new chronology for the sequence using tephra (volcanic ash) layers and the application novel radiocarbon dating methods in addition to sub-centennial scale vegetation reconstruction through high-resolution palynology. In doing so, I sought to develop understanding of the temporal and spatial variation in vegetation responses.

Interests

When I'm not in the lab or in the field, I am usually swimming. If you would like to read more about my aquatic adventures, I have a rarely updated swimming blog. Alternatively you may find me at St. Mary's as, having had a season ticket from the age of 7, I for some reason remain a Southampton FC fan and I suspect it may be too late to change my allegiances.

As someone who studies climate change, it is impossible to be apolitical. My politics, however, are not exclusively environmental. First and foremost, I am a socialist, and believe the ongoing climate crisis is a product of our fundamentally flawed economic system which continuously places profit before people and planet. If you would like to argue with me, please find me on the website formerly known as twitter.

I often feel like a bit of an outlier in academia, so I really want to support those from under-represented backgrounds who wish to pursue post-secondary academic study. If you are thinking about studying Geography/Geoscience at university, either as an undergraduate or a postgraduate, please don't be afraid to drop me an email with any questions you might have. I can't promise to have all the answers, but I will try my best to help you however I can!
