About Me

I am a Research Scientist in the Earth System Modelling and Prediction group involved in the BMBF A Coming Decade - Decadal-scale prospects for Europe project. My research is currently focused on the prediction of heat and thermal climate index extremes in Europe using typical 10-year and extended decadal forecasts. My general research interests concern climate prediction and predictability, tropical–extratropical teleconnections, climate variability on interannual and longer timescales, and practical applications of climate prediction.

I joined MPI-M in June 2024 after completing a PhD at the University of Exeter, UK. My PhD thesis was entitled The El Niño-Southern Oscillation and the Signal-to-Noise Paradox. My PhD led to novel research on the representation of El Niño-Southern Oscillation (ENSO) teleconnections in seasonal forecasts, on the simulation of ENSO dynamics and teleconnections in free-running HighResMIP models, and on understanding the signal-to-noise paradox in the North Atlantic and its relation to predictable climate drivers (in preparation).

I have been a member of the Youth and Early Career Special Interest Group of the Royal Meteorological Society (UK) since 2022.

I'm always interested in learning about, discussing, or collaborating on work relevant to my current project, my PhD, or any of my research interests.
