Short presentation
My research mainly focus on how local processes interact with large scale spatial processes (e.g. dispersal, large scale weather phenomena) on population dynamic, community structure and composition. Currently I have three main research areas:
1. Stochastic and deterministic effects on rockpool Daphnia community dynamics
2. Metacommunity structure of microbial assemblages.
3. Genetic variation and resource differentiation in freshwater fishes
