Guy started with the USGS in 2007 as a student in the Pacific Islands Water Science Center (WSC). After graduating, he transferred to his hometown of Ft. Myers, FL as a Hydrologic Technician in the Florida Integrated Science Center, where he performed a variety of gaging tasks including both SW and GW sites. In 2009, he accepted a position as a Hydrologist in the Kansas WSC. While in Kansas, he conducted a variety of studies, including sediment transport, effects of urban wastewater on receiving streams, sediment oxygen demand, and Harmful Algal Blooms (HABs). After becoming a Supervisory Hydrologist, he led the Sediment Science and Sensor Technology Unit from 2015 to 2018, which consisted of a small cadre of highly motivated hydrologists and hydrologic technicians. His Unit produced numerous publications and data releases, and has successfully conducted logistically complex and unique data collections to answer hydrologic questions of interest. In 2018, Guy transferred to the New York WSC.
