The main focus of my current research is the growth of microbial populations in heterogeneous and fluctuating environments. Microorganisms display a variety of phenotypes that are advantageous in fluctuating environments, for example the bacterial persistence phenotype, which allow a sub-population to survive antibiotic treatment. I study, via microcosm experimentation, which phenotypes are advantageous when microbes undergo range expansion under various degrees of environmental fluctuations. I also enjoy applying Statistical Physics methods to the study of ecological patterns and processes. In this line of research, I am investigating the emergence of widespread scaling patterns that characterize the distribution of species, their abundances and body sizes in ecosystems. To investigate such topics, I value the combination of mathematical modeling and microcosm experimentation.
