Dr. Kruse joined the NPS faculty in 2009. For nearly 30 years, Dr. Kruse has been involved in research and applications of multispectral, hyperspectral, and radar remote sensing at a variety of institutions including the U.S. Geological Survey, the University of Colorado, and the University of Nevada (Reno), as well as in private industry. Dr. Kruse was also one of the principal scientists that developed the original image analysis software "ENVI", designing, implementing, testing, and documenting many of the original algorithms (now used world-wide) for hyperspectral analysis. Dr. Kruse currently mentors both civilian and military graduate students and prospective Ph.D. and M.S. candidates are invited to contact him.

Physics-based exploration of diverse multispectal imaging (MSI) and hyperspectral imaging (HSI) remote sensing datasets in the visible/near infrared (VNIR), short-wave infrared (SWIR), and long-wave infrared (LWIR): Analysis of multifrequency, polarimetric SAR and Interferometric Synthetic Aperature Radar (InSAR); Characterization of reflectance and emissive spectral properties and variation of Earth-surface materials; Development of advanced data analysis strategies, methods and techniques, and prototype software; Development of knowledge-based approaches for identifying and mapping Earth-surface materials using laboratory, aircraft, and satellite reflectance and emissivity spectra and SAR measurements; Characterization and mapping of the Earth’s surface to extract information applicable to geological problems (geologic mapping, exploration for ore deposits, geothermal/hydrothermal systems, geologic hazards, and environmental monitoring) as well as to military and intelligence problems; Combined analysis of diverse remote sensing datasets and data fusion; Data integration using raster/vector layers and GIS.


Dr. Kruse has developed and currently teaches several advanced remote sensing courses linking theory with practical experience for a variety of remote sensing sensors and applications, including hyperspectal imagery (HSI), multispectral imagery (MSI), and Synthetic Aperture Radar (SAR).  Synchronous and asynchronous distance learning alternatives are under development that will take advantage of modern technology to offer similar content to non-resident students.
