PHILADELPHIA -- Like other major U.S. cities, Philadelphia is experiencing a wild resurgence of bed bugs and University of Pennsylvania junior Stephanie Lamb, one of the students in the Leonard Davis Institute of Health Economics' Summer Undergraduate Research Program (SUMR), spent the summer working on a public health research project mapping that infestation. She details that epidemiological adventure in this six-minute video. The project was typical of the hands-on experience in health services research that the SUMR students receive during their three months in the LDI program.
