The alternative to thinking in evolutionary terms is not thinking at all.

My Ph.D. work focused on the evolution of reproductive and stress-tolerance traits in Drosophila melanogaster populations experimentally adapted to chronic larval crowding for over 250 generations. Using eight large, outbred laboratory populations (four crowded-selected and four matched controls), I investigated how developmental stress affects adult fitness-related traits, including reproductive investment, sperm competition, sexual conflict, re-mating behaviour, immune function, and thermal tolerance. This work provided new insights into an underexplored question: how selection during development reshapes the evolution of adult life-history strategies.
In my current postdoctoral work, I study how mating systems influence genome evolution using Caenorhabditis elegansas a model. By experimentally manipulating reproductive mode and using evolve-and-resequence approaches, I aim to understand how outcrossing versus selfing affects the accumulation, purging, and genomic consequences of mutations. I am also investigating the evolution of immune responses and gut microbiota under stressful environmental conditions. These projects together form the foundation of a larger research program centred on how sexual reproduction and ecological stress interact to shape genomic architecture and evolutionary trajectories.
I am actively developing grants to expand this framework and would welcome collaborations with researchers working on related questions in evolutionary genomics, host–pathogen biology, and experimental evolution.
