I am currently a second-year PhD student in Mathematics at the University of Exeter, supervised by Dr. Hugo Lambert and Prof. Geoffrey Vallis. My PhD project is entitled "Understanding how the interaction between atmospheric radiation and dynamics leads to regional climate change". I investigate the sensitivity of the strength and distribution of tropical precipiation by running an idealised Atmospheric General Circulation Model (Isca: https://execlim.github.io/IscaWebsite/) using various set-ups. A major focus so far has been on the impacts of limiting evaporation from land surfaces on tropical rainfall changes, but also on the effects of topography, ocean heat transport and size and shape of land masses.
I hold an MSc in Environmental Sciences and a BSc in Physics, both from the University of Vienna. Before coming to Exeter I was working with data from a global ocean reanalysis and from in-situ observations in the Arctic gateways. During my master studies I had the opportunity to spend a semester abroad in Gothenburg, where I studied physical oceanography.
