I manage the 100,000 specimen Friesner Herbarium, a collection of pressed and dried plant specimens that serve as a reference for study of the Indiana flora. I am working with a group of botanists throughout the state to computerize our specimen records and to produce an atlas of plant distributions. In addition, I am conducting field and laboratory studies of rare native plants. I am also involved with a group studying the success of a massive prairie restoration The Nature Conservancy is undertaking in northwestern Indiana. I seek student involvement in database management, herbarium operations, field checks of plant occurrences, and genetic studies using starch gel electrophoresis of isozymes.
