I-Kuai Hung

Dr. I-Kuai Hung received his PhD in forestry from SFA and his Master of Science and Bachelor of Science in forestry from National Taiwan University. He is the author of numerous journal articles, and he is the co-managing editor of the Journal of Geospatial Applications in Natural Resources. He is a member of the American Society for Photogrammetry and Remote Sensing, the Society of American Foresters, and the Chinese Forestry Association. He is a recipient of the Kenneth G. Waterston Teaching Excellence Award from the Arthur Temple College of Forestry and Agriculture. Dr. Hung is also a recipient of the SFA Foundation’s Faculty Achievement Award for Excellence in Teaching, SFA’s top award in teaching.

David Kulhavy

Dr. David Kulhavy’s research interests include forest entomology and pest management. He holds a PhD and a Master of Science in forestry from the University of Idaho and he completed his Bachelor of Arts in zoology at San Diego State University. In addition to teaching forestry and environmental science courses at SFA, he also gives insect education presentations to elementary and junior high school students as “Dr. Bug.” He received an Eisenhower Grant for developing a program for using insects in elementary school programs. Dr. Kulhavy is a Fellow with the Society of American Foresters and he received the national teaching award from that organization, the Carl Schenck Award. He is a recipient of the SFA Foundation’s Faculty Achievement Award for Excellence in Teaching, the national teaching award from the Entomological Society of America, and was named as distinguished alumni from the University of Idaho. He is also a recipient of the prestigious William T. Hornady Gold Award from the Boy Scouts of America.

Daniel Scognamillo

Dr. Daniel Scognamillo holds a Ph.D. in wildlife and fisheries sciences from Louisiana State University; a Master of Science in wildlife ecology and conservation from the University of Florida, Gainesville; and a Bachelor of Science from Universidad Nacional de Mar del Plata in Buenos Aires, Argentina. His research interests include wildlife ecology and conservation and spatial ecology.

Daniel Unger

Dr. Daniel R. Unger’s teaching and research interests include the quantification, qualification, mapping, monitoring and management of natural resources via the spatial analysis fields of aerial photo interpretation, digital image processing, geographic information system and global positioning system technology. He holds a PhD in remote sensing and geographic information systems from the University of Idaho and a Master of Science in forest biometrics from The Pennsylvania State University. Dr. Unger is a recipient of the Kenneth G. Waterston Teaching Excellence Award from the Arthur Temple College of Forestry and Agriculture. Furthermore, he received the Carl Schenck Award from the Society of American Foresters, the most prestigious teaching award from that organization.

Jeffrey M. Williams
Technology Coordinator, Geographic Information Systems Administrator

Since 2004, Jeffrey Williams has served as the Geographic Information Systems administrator for the Arthur Temple College of Forestry and Agriculture, where he maintains geographic information systems laboratories while working with students applying geospatial technologies to ecological research. Williams earned a Bachelor of Science in geography and anthropology and a Master of Science in spatial science from SFA. He has worked in both the public and private sectors throughout his career, utilizing geospatial technologies to monitor and conserve natural and cultural resources across Texas and Louisiana. In 2003, he provided essential volunteer support following the Space Shuttle Columbia disaster, cumulating more than 250 hours of remote sensing and geospatial analysis during the first 14 days of the massive search and recovery effort. He also developed an integrated research-oriented geographic information system leading to the discovery and identification of additional existing remnants of early Spanish road features throughout eastern Texas. The geographic information system application is documented in Design of a Comprehensive Geographic Information System for the Administration of El Camino Real De Los Tejas National Historic Trail. Working with the National Park Service’s National Historic Trail’s Intermountain regional office out of Santa Fe, New Mexico, Jeff has also inventoried existing trail resources of East Texas not previously known.

Yanli Zhang

Dr. Yanlli Zhang holds a PhD in forestry and spatial science from the University of Massachusetts-Amherst. He completed his undergraduate degree at Beijing Forestry University. His research interests include geographic information systems, remote sensing, environmental modeling, and advanced geospatial analysis and application.
