Zhaohua Wang

Senior Research Engineer

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 GIS center 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 fieds 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.

As a result of the continuous research and development and in an effort of disseminating the research outcome, he has authored/co-authored eight refereed journal papers and other 12 technical conference presentations.  As a project manager and leading developer, he has delivered 10 software products to sponsors and co-authored five research project final reports.

As a PI/Co-PI, he has actively managed/led seven research projects with a total amount of $2 million, four of which are on-going projects.  As a task leader, he has significantly contributed in other eight research projects with a total amount of $3 million.  In fulfilling these research projects, he has supervised 12 Graduate Research Assistants (GRA).
