Before joining the IMAGINE Lab, Malesevic was a 3D and visual effects artist working on projects varying from architectural visualization to movies. His research focus is on 3D visualization and interaction design in augmented and virtual reality.
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, Ph.D., provides administrative support to the director of the Center for Spatial Planning Analytics and Visualization in the College of Design. She works with researchers, undergraduate and graduate 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, supervising student assistants, working with the visiting scholars, provide teaching assistance, travel and expense tracking, and event planning. If you have a “event planning” question, she’s your contact.
A researcher with the Alanta Regional Commission, Mike Carnathan’s extensive background in geographic information systems at ARC and local government make him a key asset to the Center's metropolitan planning issues.
Eric Conklin is the assistant administrator for the Office of Transportation Data with the Georgia Department of Transportation. This office is focused on the development and integration of GIS centric data including data design, collection, authentication, analysis, and display of data in support of state and federal reporting and several of the agency’s asset management systems and public services. He has more than 27 years of practical professional GIS experience centered on transportation at the local and state levels, including development of the initial E-911 system for the City of Indianapolis and development of the linear referencing system for the Indiana Department of Transportation.
Lilly Immergluck is a pediatrician, an Associate Professor of Microbiology and Pediatrics and the Director of the Pediatric Clinical Translational Research Core at the Clinical Research Center at Morehouse School of Medicine. She also is an adjunct Associate Professor of Pediatrics at Emory University and is Research Director for the Pediatric Emergency Medicine Associates in Atlanta. In 2015, she was awarded a five-year grant from the Agency for Healthcare Research and Quality to apply geospatial statistical modeling to understand the impact of socio-environmental factors that affect the transmission and spread of community-associated antibiotic resistance infections in otherwise healthy children.
