Ben Kraft studies approaches to local and regional economic development and how they may (or may not) be able to promote lasting and equitable improvements in the quality of life of individuals and communities.
Ben's professional experience includes working for the Washtenaw County (Michigan) Treasurer's Office and Office of Community and Economic Development, where he managed auctions of tax foreclosed property and Community Development Block Grant-funded housing and infrastructure projects. Previously, he helped build and locate wetlands while working as a land surveyor in Northern Virginia.
After earning a B.A. in English from The College of New Jersey in 2002, Ben went on to receive a M.A. in the Humanities from the University of Chicago in 2004, and then a Master's in Urban Planning from the University of Michigan in 2007. Ben has promised everyone who knows and loves him that this PhD will be his last degree.
Heonyeong Lee’s research interests lies in regional economic performance and planning and policy for improving regional economic resilience. He is currently participating in an NSF funded project, Resilient Interdependent Infrastructure Processes and System (RIPS) as a research assistant. Prior to joining the PhD program, he worked at the Korea Environment Institute from 2013 to 2015 where he engaged in several studies on community development planning and policy evaluation. Heonyeong earned both a bachelor (2011) and master (2013) degree in Urban Planning and Engineering from Yonsei University.
Siân Llewellyn joined Georgia Tech as a PhD student in 2018 after two decades of practice with an international design and engineering firm. Her experience in cities around the world predicated her research interest in the intersection of cities, technology and infrastructure investments in 21st Century cities.
At Georgia Tech, Siân is a graduate research assistant in a National Science Foundation funded study of the U.S. Robotics industry. She holds a master’s degree in City Planning (1998) from the Georgia Institute of Technology and Bachelor of Science in Finance (1985) and a Bachelor of Arts in History (1985) from the University of Florida.
Evan Mallen's research interests focus on climate adaptation planning, specifically though bridging the communication gap between climate scientists and planners, risk management, and use of climate analogs in adaptation planning. He currently works as a research assistant in the Urban Climate Lab with Dr. Brian Stone.
Prior to joining the Ph.D. program, Evan worked as a research associate for the Graham Sustainability Institute's Great Lakes Adaptation Assessment for Cities and the University of Michigan School of Public Health studying inter-urban communication in climate adaptation and heat vulnerability. He also organized and participated in community skill-sharing events through the Ann Arbor ReSkilling Festival and other local-scale service and education organizations.
Evan holds a BS in Physics and a Master's in Urban and Regional Planning, both from the University of Michigan.
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.

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).
Alyas Abibawa Widita’s research interests focus on understanding the influence of built environment on travel behavior. He is particularly interested in exploring this subject in cities in developing world, especially his home country Indonesia, where the built environment characteristics are arguably different from the industrialized-world cities.
Before beginning the Ph.D. program at Georgia Tech, he worked as a lecturer at the Department of Architecture and Planning, Gadjah Mada University where he taught undergraduate courses and design studio. He currently works as a research assistant at the Center for Quality Growth and Regional Development under Dr. Timothy Welch.
