Education and/or Training

M.S.	1986	Washington State University, Pullman, WA	Wildlife Biology
B.S.	1982	Utah State University, Logan, UT	Biology

Areas of Specialization and/or Research Interests

Integration of satellite remote sensing and geographic information system (GIS) capabilities with a variety of biological field data to address ecological issues of arctic environments. Remote sensing emphasis investigating dynamic processes of wildlife habitats (seasonal and annual changes, as well as global climate changes) using multi-temporal satellite imaging to study sea-ice distribution, snow ablation, vegetation phenology, fire, and sea-surface temperature. Extensive experience in wildlife satellite tracking using the Argos system aboard the NOAA polar-orbiters. Analyses of species spatial and temporal distributions relative to environmental characteristics using homerange and GIS software. Image processing of AVHRR, Landsat, SAR, and SSM/I satellite data using IMAGINE, IDRISI, and TeraScan software; data analyses using SAS software; all executed on UNIX-based computer workstations.
