Michelle Hartmann, Program Associate, graduated in May 2014, with a Bachelor of Science in Landscape Architecture (BSLA) from Rutgers University School of Environmental and Biological Sciences. Her undergraduate academic work focused on ways to inspire community activism for environmental change through landscape design and community outreach. Recently, Michelle was awarded a Merit Award from the New Jersey Chapter of the American Society of Landscape Architects (NJASLA) for her undergraduate academic thesis.  As part of the George H. Cook Scholars program, the project was developed to re-envision sustainable campus planning from the student perspective. Throughout her experience, Michelle developed technical skills in AutoCAD/AutoCAD Architecture, Adobe Suite, and ArcGIS to aid in the development of site design.  Following graduation, Michelle joined the Rutgers Cooperative Extension Water Resources Program in September of 2014 to assist with the design of green infrastructure and further develop her skills in community outreach throughout New Jersey.
