In 2008 I completed a Biology degree at Complutense University (Madrid, Spain) specialising in environmental sciences. I then went on to graduate from the School of Industrial Organisation (Spain) in 2011 with a distinction in Environmental Management MSc. 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 at Bristol University in 2014. My thesis used the HadCM3 climate model to (1) examine the impact of vegetation feedbacks on the early Last Interglacial (LIG) climate, and (2) investigate how the Atlantic Meridional Overturning Circulation (AMOC) and consequently the LIG climate were affected by freshwater fluxes injected in the North Atlantic.
My research interests focus primarily on climate dynamics and icesheet-climate interactions. My current research is to understand changes in the Greenland ice sheet and climate during the Last Interglacial.
The NEEM ice core covers the Last Interglacial period (LIG) and shows a significant warming from 129 to 114 thousand years ago (ka). It has been suggested that δ18O measurements from the core imply a high peak warmth of 8±4°C above the past millennium. Current climate models are not able to simulate this warming. Additionally, this level of warming appears to be inconsistent with Greenland ice sheet retreat shown by ice sheet models. A contributing factor to the discrepancy between δ18O temperature reconstructions and the climate and ice sheet model simulations may be the conversion from δ18O values to temperature. To investigate this I use climate modelling with embedded water isotopic code. This approach enables me to simulate isotope measurements which are then directly compared to ice core δ18O measurements.
