I have 20 years of experience and specialize in the field of anthropology with specific knowledge in the areas of archaeology, the ancient Maya and Mesoamerican art. I have published on such topics as Mayan archaeology, the history of chicle (chewing gum) and historic railroads. I have testified on stone carvings and ancient Mesoamerican cultures. I travel extensively in Mesoamerica, and can read and speak conversational Spanish.
