I am a quantitative ecologist with a background in statistical physics. My research focuses on the study of complex biological systems, ranging from cell aggregates to entire ecosystems. Using a combination of physics and mathematical and computational tools, I develop simple, yet biologically-grounded models that I then compare to empirical data. More specifically, I am interested in quantifying the interactions that occur within complex biological systems, how they are shaped by the effect of the environment, and how they impact the emergence of patterns at larger scales.
