Professional biography

My current appointment as a laboratory technician on the SWEET project (Super-Warm Early Eocene Temperatures and climate: understanding the response of the Earth system to high CO2 through integrated modelling and data) comprises the processing of deep-sea sediment samples, microscopic examination and picking of planktic and benthic foraminifera microfossils as well as performing oxygen and carbon isotope analyses using a stable isotope ratio mass spectrometer. Additionally, I am involved in supporting the lead researchers from several institutions participating on the SWEET grant by assisting in the troubleshooting and interpretation of data, and coordinating exchanges of sample material and data.

My academic background is in marine geosciences, with an MSc in Marine Geosciences (University Bremen, Germany, 2016, thesis “Late Quaternary evolution of intermediate water masses off Newfoundland recorded in the stable isotopic composition of benthic foraminifera“) and a BSc in Geosciences (University Bremen, Germany, 2014, thesis “Reconstruction of the development of a depocenter at the shelf edge off NW Portugal“).
