Brief synopsis of current research:cisco
A major goal is to contribute to elucidate the relative roles of ecological and genetic factors in the determinism of population differentiation and ultimately, speciation.

A second major objective is to understand the role of interaction between habitat structure and species life history on the determinism of genetic population structure.

A third major goal is to use the fundamental knowledge obtained in the above objectives to improve management of both wild and domestic populations, as well as conservation practices

Our laboratory is largely focussed on fish research, although other organisms are being investigated.

Our main technical expertise is in the application of molecular biology techniques to address the above issues.
