Hi there!

I am a paleoclimatologist/ paleooceanographer and a new Lecturer at the University of Southampton.

I study how Earth's climate and the ocean system have changed over time, from Cenozoic warm periods to glacial–interglacial cycles. My research focuses on reconstructing past biogeochemical cycles, spanning large-scale processes like oxygen minimum zones, productivity, and nutrient dynamics, down to finer-scale interactions of nutrient recycling and symbiosis in foraminifera (my favourite sidekick in my research!). I use a mix of geochemical tools, including lipid biomarkers and fossil-bound nitrogen and carbon isotopes, to piece together how greenhouse gases, ocean circulation, nutrient cycling, and tectonics have shaped the Earth system.

NEWS

I'm thrilled to share that the European Research Council will fund my Starting Grant project, SIDEKICC (Symbiotic Interactions in Dynamic Environments: Key Insights from a marine Calcifier since the Cretaceous).


In this project I'll study one of the most successful partnerships on Earth: symbiosis. More specifically, the alliance between foraminifera (tiny marine plankton) and photosynthetic algae. The algae are the crucial sidekick, supplying their host with extra energy in nutrient-poor environments. It is a partnership that is also vital to corals and countless other organisms, and yet we still don't fully understand it: how it first arose, how many times it has been forged and lost over time, and whether it helped life survive past episodes of climatic stress.

For the next five years, I'll chase these questions with a team (a PhD student, a postdoc, and a technician) at the School of Ocean and Earth Science, @University of Southampton, supported by this ~€2 million ERC Starting Grant.

I look forward to starting the project in 2027. Watch this space!

When did symbiosis first emerge?


How did it evolve through time?


Is there foraminifera bleaching?
