  Research Interests:

The long term goal of our research is to contribute to the diagnosis and treatment of disorders that affect balance and spatial orientation in humans and non-human animals. Our approach is to investigate mechanisms of balance and spatial orientation using the methods of neuroethology and an interdisciplinary team than includes neuroscientists, behavioral biologists, physicists, and engineers. Our experimental models are turtles and mice. These species offer a number of practical advantages for investigation of vestibular (balance) mechanisms. Because the vestibular system is highly conserved during evolution, knowledge gained from turtles and mice can be expected to generalize well to other vertebrates, including humans.

Biography:

After studying Latin and Greek in college, I fell in love with Neuroscience and have pursued that ever since... through a Ph.D., two postdoctoral positions, and a Lecturer appointment in Sydney, Australia. I came to Ohio University because I wanted to be part of a Biology Department and to conduct Neuroscience research in that context. I have enjoyed developing an interdisciplinary team to analyze mechanisms of vestibular signaling, learning from team members, and helping to establish OU's Neuroscience Program.
