He specializes in environmental assessment, regional analysis, conservation planning, mapping, and land use feasibility studies. He is a graduate of the University of Texas at Austin with an M.A. in Geography and the Environment and a B.A. in Biology. He is now on the faculty at the University of Texas School of Architecture, where he teaches graduate students to integrate geographic analysis into their research. One of his first professional jobs was with NASA. The experience changed his direction through the realization of how valuable and irreplaceable natural systems are here on this planet.
