Research & Teaching Interests

Dave teaches courses in anatomy & physiology and vertebrate systems physiology. He is a cellular physiologist with particular interests in neurons and skeletal muscle cells. His research focuses on 1) how cortical and olfactory bulb neurons respond to different patterns of stimulation and 2) how and which ion channels are involved in the excitability of different cells. He employs techniques from electrophysiology, molecular biology, and pharmacology to try to answer these questions. At Otterbein, he has expanded his research foci to include how different chemical messengers, like stress hormones, can affect the inputs and outputs of excitable cells.
