1 Jeffrey A. Wilkerson CURRICULUM VITAE 713 Center Avenue Department of Physics Decorah, IA Luther College 700 College Drive Decorah, IA phone: (563) FAX: (563) TEACHING AND RESEARCH INTERESTS My teaching interests span the physical sciences and the intersection of the physical sciences with other areas of human experience. I teach at all levels, including several courses designed for non-science majors. I work with students on many research projects, most of them centered on the acquisition of short-duration images of open star cluster fields. We study limits to photometric precision due to atmospheric and equipment effects, cycle-to-cycle variations in both eclipsing binary stars and long-period variable stars and apparent star brightness changes due to extrinsic causes such as a foreground object passing between the star and us.
