General Research Interests:
I use organic geochemistry as a tool to understand how the Earth system responds to climate change. Molecular fossils, or biomarkers, are ubiquitous in sedimentary deposits and can often be applied in both marine and terrestrial environments, making them useful proxies for reconstructing environmental change. As an organic geochemist I collaborate with researchers in a number of different fields to generate multiproxy climate records. I also work with bioscientists to understand how/why organisms produce biomarkers and how those biomarkers relate to modern environmental parameters. In addition to applications to paleoclimate problems, my research extends into areas of astrobiology, archaeology with organic residue analysis and algal biofuels.
Alkenones as a Proxy for Lake Temperature
Alkenones are globally abundant hydrocarbon lipids produced by haptophyte algae. Haptophytes produce large quantities of alkenones seasonally, not only in the oceans, but also in lakes. These lipids are utilised for reconstructing past surface ocean temperatures; however, the diversity of alkenone producers in lakes makes equivalent lake surface temperature reconstructions challenging. My research focuses on proxy development for using alkenones in lakes, including bettering our understanding of how the organism relates to the lipids that it produces.
Hydrologic and Ecosystem Change in the Sierra Nevada of Southern Spain
BECS members have taken multiple expeditions to high elevation lakes in the Sierra Nevada of Southern Spain with colleagues from the University of Granada, Spain and Northern Arizona University, U.S. to collect and analyse samples from lakes located at >3,000m elevation. We are interested in how this sensitive region responds to climate forcing and internal climate feedbacks that are driven by both natural and human impacts.
Astrobiology: Molecular Signatures of Life in Mars Analogue Environments
BECS is pleased to collaborate with Dr. Vernon Phoenix, Strathclyde University, and use molecular fossils to detect signatures of life in a unique Mars analogue - the Chilean Altiplano! The Chilean Altiplano offers the key elements that are essential to the search for evidence of life on Mars. Like the Martian surface, water in the surface soils of the Chilean Altiplano is trapped in solid form due to subzero temperatures, however, can become liquid due to intense solar radiation during the day. This combined mix of cold, high insolation flux and liquid-water-unstable conditions offers an excellent analogue to explore the preservation of molecular signs of life. BECS members are working on this exciting UK Space Agency-funded research with an aim to provide critical information on preservation and distribution of molecular signs of life that will inform sampling strategies and underpin data interpretation for ExoMars 2018.
