My early research interests were in how reptile movement patterns influence population structure.  Since arriving in Colombia in 1997, I also have developed other research programs that investigate reptile ecology, focusing particularly on nesting ecology in freshwater turtles and on lizard demographics. My studies of the interplay between dispersal and micro-geographic population structure also have extended to include other species of Colombian fauna and flora, employing both morphometric and molecular techniques.

Doctoral Dissertation:

Movement patterns relative to nesting site locations in a population of green iguanas (Iguana iguana) in Panama.

Areas of interest:

Reptile ecology, population biology, behavioral ecology, conservation and management of threatened species.


– Conservation Biology

– Behavioral Ecology
