    Ken Walsh joined Ohio University in 2009. He has taught introductory courses in mechanics, structural analysis, and steel design as well as advanced courses in structural analysis and structural dynamics. Walsh, who has published several refereed journal articles and conference papers, began his career with visiting faculty positions in the Department of Civil Engineering and Construction at Bradley University (2005-2006) and the Department of Civil and Environmental Engineering at the FAMU-FSU College of Engineering (2006-2008). He then spent one year as research faculty in the Laboratory for Modern Fluid Physics at Florida A&M University.
