His expertise includes web-based GIS application design and development, network management, database management, and system administration. His recent projects include design and development of a GIS database for the Annie E. Casey Foundation, developing a GIS framework for MEAG Power’s Location Georgia group, and developing an enterprise GIS plan for the city of Albany, Ga.
Zhaohua Wang, Senior Research Engineer
Zhaohua Wang received his Ph.D. from Tsinghua University, Beijing, China, in 1998. As a visiting scholar, he joined the School of Civil and Environmental Engineering at Georgia Tech in 2001. He joined CGIS as a research engineer II in 2007 and was promoted to a senior research engineer in 2011. During the past 10 years, he has been continuously conducting research and development in the fields of highway pavement management systems; highway pavement condition assessment using sensor technology; roadway asset inventory and management systems; and application of GIS/GPS and Information Technology for pavement rehabilitation and design.
Matthew Swarts, Research Faculty
Matthew Swarts is a member of the research faculty in the College of Design. His work focuses on the translation of human behavioral patterns and perceptions within real and virtual worlds into computer models and simulations to better understand design decisions. He often develops custom hardware sensors, interactive systems, and software applications for capturing occupant behavior, testing human spatial perception in 3D virtual environments, running discrete-event and agent-based modeling and simulation, and performing spatial analysis in the intersections between Building Information Modeling and Geographic Information Systems.
Gordon Zhang, Research Scientist
Gordon Zhang is a research scientist at the Center for GIS. He received his Ph.D. from Zhejiang University in 2013. His expertise is in landscape ecology, spatial hydrology and watershed systems, land use/cover changes and modeling, spatial optimization and decision support systems, geographic information sciences, environmental management and planning, and planning support web-application development.
Miroslav Malesevic, Digital Designer
Miroslav Malesevic is a digital designer and a researcher at the IMAGINE (Interactive Media Architecture Group in Education) Lab at CGIS and the College of Design. He graduated from the College of Civil Engineering and Geodesy in Belgrade, Serbia. Prior to joining the IMAGINE Lab, Miroslav was a 3D- and visual-effects artist working on various projects ranging from architectural visualization to movies.
Noah Posner, Research Scientist
Noah Posner graduated from Georgia Tech in 2013 with degrees in Industrial Design and Mechanical Engineering. He currently works in the IMAGINE Lab. His expertise is in 3D modeling, visualization, and physical prototyping.
Stephanie Merrick, Administrative Professional Senior
Stephanie Merrick provides administrative support to the director of the Center for Geographic Information Systems in the College of Design. She works with faculty, students, and human resources to streamline and continue to build on processes that support the research center. Her focus is on, though not limited to, budgeting for the center, hiring students, working with the visiting scholars, provide teaching assistance, travel and expense tracking, and event planning.
Recently appointed as the Atlanta Regional Commission’s (ARC) Research Division Chief, Mike Carnathan’s extensive background in Geographic Information Systems at ARC and local government make him a key asset to CGIS for metropolitan planning issues.
Leader of Esri’s education outreach team and longstanding proponent of the professionalization of the GIS field, David DiBiase has more than 25 years of experience using geographic information systems in both academia and the private sector. David’s connections to Esri, the leading supplier of GIS software and applications, and education are well-suited to help us continue our development as leaders in GIS.
Coastal Resource Specialist for the Georgia Department of Natural Resources Coastal Resources Division, Sonny Emmert, has worked extensively in Georgia’s Coastal Management Program, focusing on land conservation, coastal and marine spatial planning, and geospatial support. Sonny’s connection to Georgia state and local governments coupled with his knowledge of coastal and marine policy and technical matters is advantageous for CGIS.
David Jared, a professional engineer and Georgia Tech alumnus, is assistant state research engineer in the Georgia Department of Transportation (GDOT), where he manages GDOT’s research program. An employee of GDOT for almost 25 years and longstanding partner of many researchers at Georgia Tech, David’s background in Transportation Engineering and Planning provides our Center with unique and distinctive viewpoint on transportation research at the state level.
As Georgia’s inaugural Geospatial Information Officer, Susan Miller is working to advance the use of geospatial sciences for public policy and decision-making through partnerships across all levels of government and disciplines in Georgia. Before joining the team in Georgia, she was the director of a global GIS program for The Nature Conservancy, the world’s largest conservation organization, where she led the design and implementation of organizational-wide geospatial strategies. Susan’s role as the state’s Geospatial Information Officer will serve to foster many relationships between CGIS and agencies in the state.
