University Researcher I
Dante Vergara is a geographer with research interests in modelling space, scale, and landscape fragmentation. A specialist in Geographic Information Systems and Remote Sensing (GIS/RS), he has dealt with Land-Use and Land-Cover Change (LULCC) and urbanization models. He is continually improving a single-valued landscape index for forest fragmentation, and is currently developing an Agent-Based Model for the deforestation behaviour of colonist farmers who produce the fishbone pattern of forest fragmentation in the Amazon. He was recently Director of the Information Technology Center of the University of the Philippines Los Baños, is currently a member of the Core Technical Committee of the eUP Project, and is Project Manager of the UPLB Fiber Optic Expansion and Rehabilitation Project. He plays drums, blues harps, and fronts for a home-grown group of musician friends.
