Current research involves the application of advanced object-oriented classification techniques (eCognition) to very high resolution (0.16m) digital orthophotography, QuickBird and IKONOS satellite imagery, and LIDAR data to address issues in stormwater management, water quality (fecal contamination of rivers and streams and algal blooms in Lake Champlain), and stream geomorphology. Responsibilities include instruction of undergraduate and graduate courses in GIS, remote sensing (including digital image processing), and global environmental assessment.Program Coordinator for the UVM-wide Geospatial Technologies Minor initiated in 2007.

1987 to 1995
Senior Research Scientist, Boreal Ecology
Johnson Controls, Inc.
NASA Ames Research Center
Moffett Field, California 94035

My responsibilities included scientific program development and multi-disciplinary research in boreal ecosystems. National research activities include an assessment of the contribution of northern ecosystems to the global methane budget through the development of a circumpolar map of wetlands using recently launched Canadian, French, and Japanese satellite data. As Principal Investigator, my research focused on the utility of multi-temporal satellite and multi-parameter airborne SAR data to monitor hydrologic and vegetative factors which control biogenic trace gas emissions. In this effort I was responsible for ecological and remote sensing research, field logistics, and implementation of digital remote sensing technologies using both SAR and conventional satellite data (Landsat TM and AVHRR data). I have studied the role of plants (at the community, individual plant, and stomatal levels) and surface hydrology in the release of methane from the soil to the atmosphere.

1986 to 1987
Project Manager
TGS Technology, Inc.
NASA Ames Research Center
Moffett Field, California 94035

I was responsible for on-site management of twenty-five research scientists and technicians on a five million dollar government contract. The support contract provided analysis, modeling, and applications support for ecological research utilizing innovative remote sensing and GIS technologies at NASA Ames Research Center. I was charged with all aspects of personnel management -- recruiting, professional development, salary and benefit administration, performance monitoring, personnel evaluations, grievance resolution, personnel assignments, and establishment/monitoring of production schedules. I reported directly to the Vice President of Operations and to the President and served as sole liaison with the Government Contracting Officer and Contract Monitor. Finally, I implemented a retirement plan (401K) and salary compensation package and was the first Project Manager within the company to receive an award for outstanding performance.

1979 to 1986
Research Scientist, Arctic Ecology and Remote Sensing
TGS Technology, Inc.
NASA/Ames Research Center
Moffett Field, California 94035

Responsible for applied research and implementation of analysis techniques useful for deriving natural resource information from Landsat MSS, Landsat TM, and AVHRR satellite data. As the Principal Investigator for a multisensor analysis of Arctic and subarctic biomes, a geographic data base incorporating Thematic Mapper satellite and ancillary map data was used to predict the distribution of permafrost in a boreal forest watershed. As team leader for four diverse projects involving water quality assessment in the San Francisco Bay using TM simulator data, geobotanical discrimination of chromium-bearing parent materials with Landsat TM data, Alaska wetlands delineation and mapping using multitemporal Landsat MSS data, and an assessment of AVHRR for regional studies, my responsibilities included overseeing all aspects of the research. Collaborative research was undertaken with Cold Regions Research and Engineering Laboratory, U. S. Geological Survey, and Institute for Arctic and Alpine Research.

1976 to 1979
Geographer
U.S. Geological Survey
Department of the Interior
Moffett Field, California 94035

Duties included all phases of Landsat MSS digital analysis for earth resources inventory and mapping. Responsibilities as technical manager for the National Petroleum Reserve-Alaska project included all analysis tasks, supervision and training of analysts, liaison with state and federal cooperators, and fieldwork. This effort involved the analysis and mosaiking of ten Landsat MSS scenes. Previously worked as an analyst on the Eastern Snake River, Silver Creek, and Williston projects to determine irrigated acreage and crop types using supervised, unsupervised and modified clustering and classification techniques. Masters thesis involved the study of plant succession in response to thaw lake activity on the Arctic Coastal Plain, Alaska utilizing Landsat MSS satellite data and large scale 1949 (black and white) and 1976 (CIR) aerial photography.
