GIScCE scientists present at US-IALE

A large group from the GIScCE attended the 23rd annual meeting of the United States chapter of the International Association for Landscape Ecology (US-IALE) in Madison Wisconsin from April 6-10, 2008. Mike Wimberly organized a special session on the landscape ecology of infectious diseases that featured a range of speakers from the ecological and epidemiological fields. Geoff Henebry organized a workshop on land surface phenology that covered the concepts, terminology, data sources, and analysis methods of this emerging field. The following faculty, staff, and students presented results of their research at US-IALE. (presenters in bold)
