Guy joined MAPC’s Data Services department in 2019 as GIS Administrator. His primary responsibility is administering and managing MAPC’s spatial data infrastructure and non-spatial databases. Guy’s work includes collecting, maintaining, and publishing new datasets from external and internal sources, including the Massachusetts Land Parcel Database, the Massachusetts Vehicle Census, and the MAPC Trailmap. He also supports staff across the agency with GIS development and spatial analysis.

Guy is currently a PhD candidate at the Graduate School of Geography at Clark University, where his research focuses on urban and community forestry and the use of GIS in urban forest management. His dissertation work looks at the rates and factors of survival of trees planted by the Armenia Tree Project and assesses urban forest loss in Armenia over the past 40 years using remotely sensed imagery. Prior to moving to Massachusetts for PhD studies, Guy worked in a variety of public sector GIS positions. These included working as a GIS developer for the Wisconsin Department of Natural Resources, where he developed code in support of modelling efforts for the Wisconsin River TMDL, and implementing GIS at the City of Lancaster, PA, in support of the city’s green infrastructure program for stormwater mitigation.

He holds an MSc in Environmental Science, Policy, and Management from the MESPOM Consortium (University of Manchester, UK; Lund University, Sweden; Central European University, Hungary; and University of the Aegean, Greece), and a BA in Geography and International Studies from Millersville University of Pennsylvania.
