Alexander B Jonesi
Alexander Jonesi is a geographer with the Topographic Data Services office of the National Geospatial Program.
Alexander began his professional career interning for the National Institutes of Health (NIH) while pursuing his Bachelor's Degree from the University of Maryland. At the NIEHS, he co-authored a publication entitled Exposure to naturally occurring mineral fibers due to off-road vehicle use: A review. Additionally, Alexander worked for the USGS's Eastern Geographic Science Center (EGSC) as an intern in 2015 and after graduating, continued his work as a contractor working for EGSC and the National Cooperative Geologic Mapping Program (NCGMP) and volunteering with the Office of Science Quality and Integrity (OSQI). He contributed to several projects including a carbon research project at the Great Dismal Swamp, cataloging mangroves at Ding Darling National Wildlife Refuge in Sanibel, FL, and working with the Secondary Transition to Employment Program (STEP), which provides young adults from local high schools with learning disabilities job skills to help them transition from school to work. Following the conclusion of his contract, Alexander worked as a Pathways Student Trainee for the Topographic Data Services (TDS) office of the National Geospatial Program (NGP) while pursuing his Master's in Geospatial Intelligence. Since graduating, Alexander works as a geographer for NGP's TDS office, working with the 3D Elevation Program (3DEP) and 3D Hydrography Program (3DHP).
