Josh Reyling | Geospatial Technical Support Lead

Josh has a Professional Science Masters from CSU.  He completed his undergraduate in Geography with an emphasis in GIS at UNC (Greeley, not Chapel Hill).  Professionally, Josh has spent over a decade working with diverse clients – from small municipalities to the Department of Defense – troubleshooting/ streamlining processes and designing project workflows.  He gets a great sense of calm and well-being from organized data structures and elegant answers to problems.  Outside of school, he can be found on a calm river, in a canoe.

Dan Carver | Geospatial Research Analyst

Dan Carver is a spatial scientist and educator working and living in Northern Colorado. His active projects center around the conservation of agriculturally-relevant biodiversity, reproducible reporting, and how best to convert information to understanding on a personal level. He enjoys running, cooking, and many of the other complexities of life on our planet.

Kevin Worthington | Maps and GIS Data Specialist

Kevin Worthington is the Maps and GIS Data Specialist at the Centroid. He works in collaboration with CSU Libraries to support managing, storing, indexing, and sharing archival geospatial data. He has wide and varied experience in data science/analysis, programming, database management and web development.

Kevin earned a Master’s degree in Environmental Applied Science and Management from Ryerson University in Toronto, Canada. His Master’s thesis involved developing a web-based application for managing, visualizing, and analyzing mobile air quality measurements collected by citizen scientists as they bicycled around the city of Hamilton Ontario.

His interests include mountain biking, rock climbing and hiking.
