About Me:

I develop and maintain spatial databases (ArcInfo and ArcView) and habitat associations for vertebrates (mammals, birds, reptiles, and amphibians) in Illinois. I also develop and assess vertebrate distribution maps and habitat relationship models using vegetation distributions derived from satellite imagery and assist in classification of TM satellite imagery, to community level classification standards.  I am currently serving as the GIS/Remote Sensing Specialist and Illinois Gap Analysis Project Coordinator for the Wetland Science Program.
