Brief synopsis of current research:
 |
| Red melanzona morph and less colorful parae morph
of male Poecilia parae |
My main research is on the molecular sytematics and sexual selection in the guppy (Poecilia reticulata) and closely related species (Poecilia parae, Poecilia picta, and undescribed species), from northeast South America. The guppy is the common aquarium guppy, with multicolored males. The closely related species also show interesting morphs, as shown in photographs. My lab is also funded by National Geographic Society to look at conservation biology and conservation genetics of these species.
