Professor Milan Kováč, a 2014 Fulbright Fellow in cultural anthropology at Missouri State University, head of the Comenius University’s Department of Comparative Religions, is the founder of Mesoamerican and Maya studies in the Slovak Republic. His international research team in the northern Guatemalan jungle -- using new aerial laser scanning -- discovered remains of a Mayan metropolis of 15 million people (and 60,000 buildings, plazas, and pyramids) that collapsed in the 9th century.
