Professor Emeritus



Email: David W Biers


Dr. Biers joined the faculty in 1976 after teaching at the State University of New York at Geneseo. From 1986-2001, he served as the Director of the Human Factors Graduate Program and as liaison between the University and the Research Institute to provide on-campus human factors and training support. He also served as President of the Southern Ohio Chapter of the Human Factors and Ergonomics Society. Dr. Biers served as chairperson of the department for seven years.

His primary teaching responsibility has included experimental psychology, statistics, and computer applications at the undergraduate level and research design, statistics, and human-computer interaction at the graduate level. Dr. Biers has taught graduate courses in advanced research design, analysis of variance, multiple regression, multivariate statistics, human-computer interaction, and program evaluation.

Dr. Biers was awarded the College of Arts and Sciences Outstanding Teaching Award in 1982 and the Alumni Award for Excellence in Teaching in 1988. Major non-teaching responsibility has been advising students and faculty in the design, statistical treatment, and computer data analysis of their research.
