Evolution, Speciation, Selection, hitchhiking, local adaptation

Population genetics, Molecular Evolution, Marine Biology

I am using molecular markers together with lab experiments, field studies and theoretical developments in order to better understand evolutionary mechanisms involved in the processes of adaptation and speciation. I am mostly studying marine invertebrates because they possess unique biological characteristics that affect their genetic diversity, structure, and evolution including high fecundities, large population sizes, external fertilization with broadcast spawning, and extended larval dispersal.

My work has addressed questions about (i) heterozygosity-fitness correlations, (ii) genetics at larval stage, (iii) marine hybrid zones, (iv) mechanisms of reproductive isolation in the sea, (v) synonymous and non-synonymous substitution rates, (vi) adaptive protein evolution, and (vii) genetic hitchhiking in subdivided populations.
