Research Interest:

My research interests include galactic structure, planetary nebulae, and late stages in stellar evolution. I have carried out astronomical research at the Cerro Tololo Inter-American Observatory in Chile, at the Kitt Peak National Observatory near Tucson, Arizona, at the Laboratory for Astronomy and Solar Physics at the NASA-Goddard Spaceflight Center in Greenbelt, Maryland, at the Lowell Observatory in Flagstaff, Arizona, and at the Sproul Observatory in Swarthmore, Pennsylvania. Most recently I have worked with colleague Wulff D. Heintz of Swarthmore College on the monitoring of suspected variable stars. Widener University is a member of the National Undergraduate Research Observatory (NURO) which operates a 31-inch telescope on the Anderson Mesa outside of Flagstaff, Arizona. (www.nuro.nau.edu).
