Research interest

I study how selection shape the evolution and maintenance of adaptive diversity, from genomes to communities. To identify and characterized the signature of selection across levels of biological organization I integrate clever experimentation in nature to state of the art genomic research. I focus on Amazonian species of butterflies and amphibians with warning colorations of toxicity since they provide a visually compelling example of local adaptation suitable for investigations on how selection regimes are shaping adaptive diversity. My approach enables to fill the gap between the identification of relevant genetic variants and the ecological mechanisms explaining their success in natural populations.

Moreover, I’ve built and I’m currently managing the Tarapoto Butterfly Research Station which provide, since 2011, easy access by the scientific community to the rich ecosystems of the Peruvian cordilleras-Amazon transitional zone. The successful implementation and management of this research centre is attracting professors, graduate and undergraduate students from International Universities, and Institutes.
