Curriculum Vitae


John Rogan joined the faculty as Assistant Professor in Fall 2003. Dr. Rogan received his Ph.D. (Geography) degree from the joint doctoral program at San Diego State University and the University of California, Santa Barbara, where he was funded by a research grant from NASA's Land Cover and Land Use Change Program. He received M.A. and B.A. degrees (Geography) from the University of Arizona.

Current Research and Teaching

John is a geographer specializing in landscape ecology, fire ecology, optical remote sensing and GIScience. Recent research projects have involved monitoring land cover change in California using remote sensing date, mapping wildfire burn severity in southern California and southeastern Arizona, and mapping forest types in Massachusetts using multi-season Landsat data. John is currently working on three funded research projects:

  • mapping tropical fire in the southern Yucatan Peninsula (Mexico) using MODIS active fire data (NASA Land Use and Land Cover Change Program)
  • mapping emerald ash borer effects using hyperspectral imagery in the greater Detroit region (in association with USDA-APHIS and Clark Labs)
  • characterizing the impact of weather extremes in southern Yucatan Peninsula to understand ecosystem and landscape-level responses, and to increase the technical and scientific capactity of protected area agencies at Calakmul and Sian Ka'an Biosphere Reserves (Gordon and Betty Moore Foundation)
