After working in industry for a number of years in plant engineering and related areas, Dr. Herman earned his doctorate and joined the Department of Civil Engineering at Ohio University. He teaches undergraduate and graduate courses in transportation engineering, including the capstone senior design course in land development.

 

Research Interests:
Dr. Herman's principal area of research interest is in the environmental analysis of transportation systems. He has conducted research for the Federal Highway Administration (FHWA), the United States Department of Transportation (US DOT) and the states of Ohio, Tennessee, Washington, and Pennsylvania. Dr. Herman's studies involve the effects of tire/pavement noise and the design and effectiveness of noise abatement methods, such as walls and berms, to improve their performance. He is also active in acoustical instrument research and development to facilitate the study of long range traffic noise propagation.


Research Interests: environmental analysis of transportation systems, the effects of tire/pavement noise, acoustical instrument research and development to facilitate the study of long range traffic noise propagation

All Degrees Earned: Ph.D., Vanderbilt University, 1993.
