Throughout his career he has continued to explore historical climates, geochemistry, and new dating techniques, focusing on the Sahara and the Antarctic. Dr. Giegengack also directs the Institute of Environmental Studies at Penn, an interdisciplinary research center focusing on the complex political, scientific and economic factors involved in managing our environmental resources. One of the Center's programs involving Penn students is a seminar course taught by Dr. Giegengack. Working with students at nearby Shaw Middle School, the undergraduates investigate lead toxicity in West Philadelphia homes. The course teaches the Penn students research methods and helps local residents to improve the urban environment, as well as creating personal ties between the university and its neighbors.
Many students continue their work in graduate school in areas as diverse as law and medicine.
Dr. Giegengack's innovative research projects, in addition to his students' work, are contributing to a successful and comprehensive way of addressing environmental issues from a truly interdisciplinary perspective.
