Biography
In 2008 I completed a Biology degree at Complutense University (Madrid, Spain) specialising in environmental sciences. From 2011 until 2013 I worked in the Climate Change Division of Repsol as an environmental consultant before figuring out that climate modelling was what I truly wanted to do. I have always been fascinated by global environmental change and modelling of the Earth System so undertook a Masters degree in Climate Change Science and Policy in 2014 and obtained a PhD in Physical Geography from the University of Bristol in 2020.
Research interests
My research interests focus primarily on past climate change. I am interested in using climate models to develop a better understanding of the changes in the ice sheet, sea ice, and climate over the last 800,000 years.
I am currently involved in the EU-funded ANTSIE project, investigating summer sea-ice variability on the Antarctic margin during the last glacial period. In this task, the main objective of my study is to compare the features resulting from Dansgaard-Oeschger-like oscillations from a range of climate models with a novel archive of past sea-ice environments from snow petrels’ (Pagodroma Nivea) regurgitated stomach oils.
My previous research has particularly focused on explaining the Last Interglacial (LIG) Greenland δ18O maximum. In particular, I used the isotope-enabled HadCM3 climate model to investigate the isotopic signature of Arctic sea-ice changes and Greenland Ice Sheet retreat during the Last Interglacial and to determine whether this can be reconciled with Greenland ice core records.
