I teach courses in the areas of cell biology, cellular physiology, and plant physiology.
My research focuses on understanding mechanisms of cellular dehydration tolerance. I use seeds and moss to study how water loss affects cell structure and how some cells are adapted to survive the loss of almost all their water. I also do research on seed longevity, which is dependent upon processes that occur in the dried tissues. Understanding the physical and chemical changes that occur in dehydrated cells may help us improve the longevity of seeds and other genetic resources when they are stored.
