Bob Brennan, Jr, Ph.D.
Bob Brennan Jr., Ph.D., is a professor of biology and is currently serving as the associate dean for the College of Mathematics and Science. He was born and raised in Emmetsburg, Iowa, which is a small farming community in northwest Iowa. Brennan is one of five children. His father was a carpenter and his mother worked as a nurse at the county hospital. He attended the University of South Dakota where he played football and received a B.S. in biology. He earned his M.S. in veterinary medical sciences (microbiology) from Louisiana State University and Ph.D. in medical sciences (microbiology) from Texas A&M Health Sciences Center. Prior to coming to UCO in 2009, Brennan worked at 3M as a microbiology specialist in their Medical Division. His wife, Martha, is the Head Men's and Women's Track and Field Coach at Southern Nazarene University. They have four daughters; Grace, Eve, Ivy and Bella.

The primary focus of my lab is to investigate microbial pathogenesis, which includes projects to study the role of Staphylococcus aureus biofilms in chronic wound pathogenesis, antibiotic resistance, and the prevalence and distribution of ticks and tick-borne pathogens. During my 12 years at UCO, I have had numerous students involved in research, scholarly, and creative activities, which have led to a number of student co-authored peer reviewed publications and presentations at local, regional, and national conferences.
