I have been researching diverse aspects of Caribbean geology and palaeontology since 1986. Research is currently focussed on the vertebrate palaeontology of the Late Pleistocene of the Red Hills Road Cave of Jamaica, in collaboration with Dr. L.W. van den Hoek Ostende, and Upper Oligocene echinoids of the island of Antigua, funded by the Florida Museum of Natural History and its donors.
