I use a technique called electrophysiology to attach tiny electrodes to cells and measure the flow of electrically charged ions through the membranes of living cells. Working with collaborators in the Biology and Psychology departments, I have several ongoing projects. One project studies proteins which are important for new nerve cells to develop electrical excitability. Another second project studies how nerve cells in the corpus callosum make functional synapses onto other brain cells. A third project studies how high levels of potassium ions in tear fluid helps project cells on the surface of the eye from UV damage, and investigates how tear ducts help create the high level of potassium in tears.
I also study issues at the intersection of science and Christian faith.
