Work History

Mar 2010Present

GIS Analyst

Parsons Corporation

Data management work includes gathering, cataloging, updating and presenting all GIS dataset required for each project. Also responsible for coordinating geospatial data transfers between subcontractors, establishing project-wide coordinate systems and converting to and from Google Earth files and CAD datasets.

Analytical work includes creating shapefiles from digital and physical sources, managing and updating attributes, and identifying and quantifying resources along corridors.

Cartographic work includes developing map templates for each project, and creating maps for reports, internal memos and plots for public meetings.

Sample Project Types include:
• Long Range Planning and State Improvement Programs: Responsible for mapping transportation needs using statewide project lists as well as providing all cartographic materials. Also assists in creating the final geospatial data packets and coordinating efforts among staff and consultant team members as well as with local governments.

• Environmental Impacts Statements and Environmental Assessments: Assists in preparation of NEPA documents. Evaluates qualitative and quantitative environmental impacts along corridors. Assists with the management of and preparation of deliverables for the following tasks: project-related mapping, Agency Coordination, Land Use, Social & Economic Impacts, Farmlands, Right of Way & Relocation, Natural Resources, Visual Resources, Parks, Recreation Areas, & Open Spaces, Hazardous Materials, and Indirect Impacts.

GIS Laboratory Intern

Conservation Ecology Center, Smithsonian Institution

Assisted with all GIS needs for the Conservation GIS Lab, including conducting research for primary projects, and teaching the GIS Training Courses and Workshops.

Main Work included:
• Giant Panda Research (Published): Evaluated Giant Panda habitat by interpreting current species requirements from literature, extracting environmental and climatic variables from existing geospatial datasets, and projecting the data into the future.
• Dry Forest Identification (Published): Compared and mapped the accuracy of multiple existing land cover sources in identifying dry forests in South East Asia.
• GIS Training: Taught three GIS Training Courses and one International Workshop offered by the Smithsonian. Duties included preparing all learning material, as well as updating content and authoring new chapters.
