I am studying the causes and influences of heterogeneous energy supply in cell and evolutionary biology, capturing the dependence of life's essential process on ATP. My research uses models and simulation to explore how ATP variability arises within and between cells,  population dynamics, and the evolution of co-operation and competition.
