Research Interests

I am interested in the role that winds have played in shaping the climate of the Antarctic Peninsula and the Amundsen-Bellingshausen Seas region over the last centuries. In order to assess how changes in wind strength and atmospheric circulation have impacted the regional climate, it is necessary to study how winds have evolved in the past.

Ice cores have proved to provide a wealth of climate information through the use of proxy records. As part of my PhD, I am developing a novel proxy for localized wind conditions based on the abundance and diversity of marine diatoms entrained in ice cores retrieved from the Antarctic Peninsula, West Antarctica, and sub-Antarctic islands. Combining the analysis of already proven long-range wind strength and circulation proxies (such as dust concentration, Sr/Nd isotopes and continental ions), with sea salts, water stable isotopes, marine organic compounds (such as Methansulphonic acid (MSA)) and diatom abundance, will enable to develop an ice core multi-proxy reconstruction of regional wind strength and atmospheric circulation over centennial timescales.
