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. 

Selected Projects:

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. Two long sediment cores were collected from a lake, Laguna de la Mosca and a peat bog, Borreguil de Caldera. The sediment core from Laguna de la Mosca extends 2-meters into the lake sediment and is the longest core ever recovered from this high elevation in the region. Preliminary radiocarbon dates suggest that the record extends back just over 8,200 years of climate history. The core from Borreguil de Caldera is 56-centimeters long and covers the last 4,000 years of climate history. Initial biomarker and pollen analyses are underway from these cores to determine how hydrology has changed in the past and how the ecosystem responded.
