My research revolves around improving our understanding of modern and ancient phytoplankton and their relationships with the environment - now, in the past and in the future. I maintain a broad, interdisciplinary background in marine science, biological oceanography, micropaleontology and marine and paleo-genomics. I am particularly passionate about ship work at high latitudes and exploring marine sediment records to investigate phytoplankton-environment relationships over geological timescales. The key to pursuing this research is my use of state-of-the-art molecular techniques, including the newest tools for the analysis of ancient DNA from the seafloor.
Currently, I am applying these novel ancient DNA techniques to reconstruct East and West Antarctic ecosystems. My focus is on two Antarctic regions that are highly sensitive to climate change, the East Antarctic Sabrina Coast and West Antarctic Iceberg Alley. I have been part of two Antarctic expeditions, the 2017 'Sabrina Seafloor Survey' on board the RV Investigator (IN2017_V01), and the 2019 IODP Exp. 382 'Iceberg Alley and Subantarctic Ice and Ocean Dynamics' on board the RV Joides Resolution, to collect sediment sample specifically for this research. To undertake this work, I have recently been awarded an ARC DECRA Fellowship 2021.

Marine phytoplankton are globally important microorganisms that live in the ocean’s surface. When these tiny organisms die, they sink to the seafloor and over time build up complex layers in the ocean sediments. By extracting ancient DNA from such sediments, past phytoplankton communities can be reconstructed, providing information on past environmental conditions and climate. This novel knowledge about past marine community adaptation to previous regional and global warming periods helps inform predictions of future marine ecosystem resilience guiding management efforts of marine ecosystems during present-day climate change.
Study opportunities on all levels (Internships, Honours, Masters, PhD) are available with regard to the reconstruction of Antarctic phytoplankton communities and their responses to variations in climate. Sediment cores used for this research were collected off East and West Antarctica, and are dated to the Last Glacial Maximum (~20-25 kyr). This research is highly interdisciplinary, spanning across marine science, biological/palae-oceanography, and palaeo-genomics, and a good understanding in at least one of these disciplines is required. Study activities include, for example, marine field-work (topic-dependent), laboratory tasks, bioinformatics and data analysis.
