Timothy J. Polnaszek

Dr. Timothy J. Polnaszek serves as an Associate Professor in the Biology & Biochemistry Department at Belmont Abbey College. His teaching portfolio includes General Biology and Ecology courses, supporting both Bachelor of Science in Biochemistry and Bachelor of Arts or Science in Biology programs, as well as pre-professional pathways.

Dr. Polnaszek's research focuses on animal behavior, comparative cognition, ecology, and evolution. His work explores how animals communicate through signaling systems, with particular attention to signal reliability, receiver psychology, and cognitive constraints in animal decision-making. Notably, he conducted an experiment where a bee learned to open a tiny lid to access food rewards, demonstrating innovative problem-solving in insects.

• B.S. from North Dakota State University
• Ph.D. from the University of Minnesota
• Postdoctoral research at the University of Arizona

His publication record demonstrates consistent research in animal signaling systems, with a focus on experimental approaches to understanding signal reliability and animal cognition. His work spans theoretical frameworks in evolutionary biology and empirical studies with various animal models including bumblebees and woodchucks.

Dr. Polnaszek is known for sharing fascinating facts about animal life and behavior with his students. Outside the classroom, he is active with the ultimate frisbee club on campus.
