Research InterestsI'm an evolutionary biologist interested in the causes and consequences of population structure, the evolutionary importance of hybridisation and the study of speciation. My work has focused mostly on the genetic, ecological and behavioural changes associated with the first stages of speciation in butterflies and lizards. More recently, I've started a research project on the adaptive radiation of high-altitude plants in the Andes (Espeletiinae).
• Hybridisation and adaptive radiation in the Espeletiinae, a group of high-altitude plants from the Andes.
• Hybridisation, introgression and speciation in Heliconius butterflies.
• Speciation in high-altitude Satyrinae butterflies from the Andes.
• Ecology, population structure and speciation in Cnemidophorus lizards.
• Ecology and population genetics of green turtles (Chelonia mydas) in Aves Island, Venezuela (Marco García's Ph.D project).
