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.
Currently, I am working with ancient phytoplankton DNA from sediment cores taken along the coast of Australia. Genetic community data from these samples will be correlated with the timing and distribution of harmful algal blooms, and the spread of invasive microalgal species, along the East Australian coastline.
