Southeastern welcomes students back for the start of classes this week while we continue to keep all faculty, staff and students who are not yet able to make it to campus in our thoughts as the region works to recover from devastating flooding.
 
We attempted to reach ALL our students in recent days, but we realize communication has been difficult, if not impossible for some. If you are just now able to see this message, please contact enrollmentservices@southeastern.edu so we can have a better understanding of your status and work with you so you can attain your educational goals.

Research Interests: Neurophysiology.

My broad interests are in the function of the nervous system, mainly in humans. The human brain is comprised of roughly a trillion (1,000,000,000,000) nerve cells, called neurons, that make about a quadrillion (1,000,000,000,000,000) connections, called synapses, with other neurons. By studying the function of individual neurons and synapses, we can begin to understand the behavior of neuronal circuits and systems. This information may eventually lead us to an understanding of the underlying mechanisms that produce the remarkable complexity and diversity of human behavior.
Biophysics of Ion Channels. Normal function of excitable tissues such as the nervous system is dependent on transmembrane proteins called ion channels, and the the function of these ion channels is dependent on normal molecular structure. Studying the function of ion channels with altered or mutated structure provides an understanding of the biophysical relationship between protein molecular structure and physiological function. This information can be directly related to heritable mutations that underly human diseases such as epilepsy, myotonias, and sudden cardiac death.
