Research

As a Research Associate IV at the University of Rhode Island’s Department of Natural Resources Science’s Environmental Data Center, my work encompasses using Geographic Information System (GIS) technology for the analysis of cultural and natural resources data. Typically, my interests have focused on dynamic visualization of complex spatial and scientific data in a 2-D and 3-D setting. In addition, I enjoy automating the processing of large data sets and finding better ways of sharing information using the Internet.

For over 30 years I have worked on GIS related projects for agencies such as the National Park Service (NPS), the National Oceanographic Atmospheric Administration, the Town of New Shoreham, and the National Aeronautics and Space Administration. Project topics include content creation and administrations of ArcGIS Online and NPS Portal; viewshed modeling; automated mapping vegetation using digital orthoimagery; and LiDAR data processing. Away from home, I have worked with a coastal management agency in Ecuador to establish a GIS to monitor mangrove forests and I have trained geologists from the Azores, Portugal on how to use GIS to model areas vulnerable to landslides.

Current Projects

I am overseeing work done at The Field Technical Support Center for GIS (FTSC) at the University of Rhode Island. We provide GIS services and support to National Park Service (NPS) parks and offices throughout the Northeast Region (NER). The goal of this partnership between the NPS and URI is to foster research and education using GIS to support and promote natural and cultural resource preservation, recreation, and local/regional planning in partnership with state and local government agencies, as well as nonprofit conservation and historic preservation organizations. The FTSC provides an arena for land management agencies and organizations to coordinate data collection and analysis on landscape scales and for researchers, students, land managers and planners to work together on issues related to this evolving technology and to learn from each other. Innovative applications, new data and procedure development methods, and technical forums provide researchers and students with opportunities to enhance their GIS skills using National Parks and other areas with complex land management issues as living laboratories.

In addition, I have been working with the URI TickEncounter Resource Center to administrate their TickSpotters system and analyze spatial and non-spatial data for public outreach and education.  New project work includes data processing and analysis to support the distribution of muskrats, beavers, and otters in Rhode Island.
