    Professor Ronald Eastman received his Ph.D. from Boston University in 1982. He joined the department in 1981 and served as Director of the Graduate School of Geography from 1998-2002. His interests include geographic information systems, remote sensing, and cartography . He is the Director of Clark Labs within the George Perkins Marsh Institute and its associated projects for the development, production and support of the Idrisi and Cartalinx software programs. Idrisi for Windows is the largest-selling raster-based GIS in the world with more than 35,000 users. Dr. Eastman is also a Visiting Professor at the Department of Resources and Environmental Sciences at Beijing Normal University. He has worked extensively in the area of GIS development and its applications, particularly in an international development setting. Through UNITAR, UNEP and USAID, he has participated in field work throughout Asia, South America and Africa.
