Dr. Kim
Dr. Kim is an associate professor in Civil and Construction Engineering at the Southern Polytechnic State University. Dr. Kim received his M.S from Georgia Tech and Ph.D. from Texas A&M University, College Station, TX. Dr. Kim is specialized in infrastructures assessment and rehabilitation, pavement design, construction, and performance evaluation, and pavement related materials, and construction materials. Dr. Kim has conducted research in the fields of pavement materials, geotechnical and transportation engineering. He has more than 15 years of professional experience as a professional in those areas and conducted research for a veriety of Federal, State, and local government agencies.  Dr. Kim have published over 35 papers and reports on construction material and pavement technology and he has managed about $180,000 annual research funding since he estabished the Georgia Pavement and Traffic Research Center. 
Jidong Yang, Ph.D., P.E.
Assistant Professor in Civil and Construction Engineering
678 - 915 – 3018,
Dr. Yang is an assistant professor in Civil and Construction Engineering at the Southern Polytechnic State University (SPSU). He received his Ph.D. degree from the University of South Florida in 2004. Dr. Yang is a professional engineer with over a decade of combined industrial and research experience. Over the past decade, Dr. Yang's research has been focused on several areas, including pavement performance modeling, pavement management, traffic operations and safety, geometric design, and intelligent transportation systems. Prior to joining the SPSU, Dr. Yang served as Program Manager for the City of Chattanooga's Intelligent Transportation Systems and has directly overseen multiple ITS contracts (in a total amount of 11.4 million) funded by Federal Highway Administration (FHWA) and Tennessee Department of Transportation (TDOT). Dr. Yang received Young Professional Scholarship Award from the Transportation Consultants Council, Institute of Transportation Engineers (ITE) in 2007. Recently, He has been recognized as 2013 Outstanding Reviewer by American Society of Civil Engineers (ASCE).
Richard Ruhala, Ph.D., P.E.
Associate Professor in Mechanical and Systems Engineering
678 - 915 – 6855,

Dr. Ruhala is an Associate Professor at SPSU since 2010 in the Mechanical Engineering program, within the Systems & Mechanical Engineering Department. He received BS in Mechanical Engineering from Michigan State University and Ph.D. in Acoustic from Pennsylvania State University. Dr. Ruhala's research interest is in pavement/tire interaction noise, transportation noise, vuvuzela noise, and environmental noise

Associate Professor in Mechanical and Systems Engineering
Dr. Khalid's research focuses on application of Unmanned Aircraft Vehicle (UAV) into transportation and pavement engineering fields. Also, Dr. Khalid's research is to design, build, and fly an Autonomous Aerial Patrol and Surveillance System (APSS). His goal is to create a safe autonomous UAV system that is equipped with visual, infrared, and heat seeking cameras. The autonomous feature of the vehicle will eliminate the need to actively control the vehicle at all times. The operator will have the campus map on a mobile device e.g. iPad. The operator will be able to point on the map, which will send a command to the vehicle to fly to the corresponding location on the map and hover or loiter there to send live video feedback. 

Assistant Professor in Electrical and Mechatronics Engineering
678 - 915 – 3004,
Dr. McFall's educational background includes BS from Virginia Tech, Master’s degrees from MIT, as well as a Ph.D. degree from Georgia Tech, all in Mechanical Engineering. Dr. McFall's current research agenda focuses on applying artificial intelligence to solve computational science problems. He developed the length factor artificial neural network method for solving coupled systems of differential equations. This method offers several benefits over the traditional finite element method including a continuous and differentiable solution over the problem domain, a square grid training mesh, and ease of implementing complicated nonlinear differential equations. 
Associate Professor in Electrical and Mechatronics Engineering
678 - 915 – 5574,

Bill Diong received his Ph.D. in Electrical Engineering from the University of Illinois (Urbana). He is specialized in electrical energy harvesting from pavement and infrastructures. Dr. Diong had served as a project co-PI and then consultant on a multi-million dollar NIH grant that he helped co-author the proposal on the modeling of respiratory system dynamics. At this point in time, he has authored or co-authored slightly more than 80 refereed journal and conference papers. 


Assistant Professor in Electrical and Mechatronics Engineering
678 - 915 – 7317,
Dr. Ying Wang is an assistant professor in Mechatronics Engineering at Southern Polytechnic State University. His research interests are application of robotics, controls, mechatronics, computer vision and machine learning into Pavement and Transportaiton Engineering. He has published more than 40 journal and conference papers in the above areas. He received the Ph.D. degree in robotics and mechatronics from The University of British Columbia, Vancouver, BC, Canada in 2008. He also received his master’s degree (1999) and bachelor’s degree (1991) from Shanghai Jiao Tong University, China. Before he came to SPSU, he ever worked as a postdoctoral research fellow in The University of British Columbia for one year.
