John Lee
John Lee

John Lee began his studies at Georgia Tech in 2013 as part of Georgia Tech’s first class in the Master of Geographic Information Science and Technology program. John's research interests include understanding the significance and interrelationship of the multiple criteria that influence current and future land use within urban spaces. He envisions the development of a framework of ‘Best Practices’ methodologies for planners to follow in modeling urban change that will facilitate more accurate predictions of its impact on traffic congestion, the environment, and quality of life for a municipality regardless of their stage of growth culminating in a self-learning, self-adjusting system.

Since 2007, John has been an instructor at Southern Polytechnic State University in the Department of Civil Engineering Technology. While there one of his recent research projects included a quantitative assessment of wall stress and deformation and the collection techniques used to measure the data. The goal of the project was to validate the use of a rapid housing reconstruction technique which proposed using concrete rubble to rebuild temporary housing within the earthquake affected regions of Haiti.

Prior to joining Georgia Tech and Southern Polytechnic State University, John spent 21 years in telecommunications research and development at BellSouth in Atlanta GA, at EIRCOM in Dublin, Ireland and at AAPT in Sydney, Australia. He has degrees in Computer Science (BS ’85), Economics and Finance (MBA ’98), Surveying and Mapping (BS ’13) and Geographic Information Science Technology (MS ’14. He is currently leading a special projects team that is developing the Storm Preparedness Guidelines for the City of Atlanta. 

 

Yongsung Lee
Yongsung Lee

Yongsung Lee's research focuses are the relationship between urban form and travel behavior, and its implications to energy consumption and greenhouse gas emission. In his Master's Thesis, Yongsung wrote about the price elasticity of automobile gasoline and its variation depending on different urban forms and policies; all else being equal, the more compact urbanized areas are, the more sensitive to gasoline price their residents are. Recently, Yongsung is analyzing the impact of high energy price on urban form.

Before joining Georgia Tech, Yongsung worked as a research assistant at the Korea Research Institute for Human Settlements (KRIHS) from 2008 to 2010. Yongsung earned a MUP (2012) from the University of Illinois at Urbana-Champaign, and a M.E. in Architectural Planning (2008) and a B.S in Architecture (2003) from Seoul National University in South Korea.

Mark Sloan

Mark Sloan’s research interests involve the quest to create more sustainable urban living environments through study of the influence of space (the occupiable voids between buildings) on human social and consumptive behaviors. He seeks to find “tipping points” for new models, codes, and assessments that create better exterior spaces for people, that improve economic, social, and environmental sustainability.

Mark is a recently retired U.S. Air Force Colonel, who served as an Air Force Civil Engineer, with assignments at Headquarters US Air Force at the Pentagon, and on command staffs at US Air Forces in Europe and Air Force Global Strike Command.  He is a two-time squadron commander, including Base Civil Engineer and Commander of a civil engineer squadron in the Middle East, and later Commander of the Air Force’s civil engineer technical school.  He most recently served as Deputy Director for the Air Force’s worldwide design and construction directorate at the Air Force Civil Engineer Center in San Antonio, Texas. 

After earning a B. Design in Architecture from the University of Florida in 1991, Mark then earned his M. Arch professional degree from the University of Florida in 1993, and an M.S. in Strategic Leadership from the Air Force Institute of Technology in Dayton, Ohio in 2006.  He is also a graduate of Air War College (distance learning program).
