Research

Research Interests

My research focuses on the detection and attribution of temporal changes in the climate system and carbon cycle, with special emphasis on abrupt changes. I use statistical methods such as change point detection to analyse observations and model outputs. I am also interested in developing flexible and useful statistical tools suitable to study and monitor climate and environmental change.
