I am a research fellow at Lund University and Imperial College London (Silwood park). I am interested in how organisms and ecological communities respond to environmental changes such as global warming, intensified agriculture or contamination.
My research focuses on the seasonal timing of biological events (phenology) such as flowering, bird migration or insect pollinator emergence. How does the timing of important actions in species annual cycles influence population growth rates and ecological interactions? If interacting species go out of sync (phenological mismatch) because they react differently to increased temperatures, what are the long- and short term consequences?
I am the principal investigator of two interlinked projects in which we study how pollinator populations are affected by changed seasonal variation in flower resources and episodes of pesticide exposure.
My background is in theoretical ecology and I apply various mathematical tools such as game theory, population dynamic models and optimization theory to study problems in ecology and evolution.
