A. T. Charlie Johnson, Rebecca W. Bushnell Professor of Physics and Astronomy, presented early results on his innovative, collaborative research with faculty and researchers from Perelman School of Medicine and School of Veterinary Medicine at the annual American Society of Clinical Oncology meeting in early June. Together, Penn researchers are working to develop an "electronic nose" that can detect certain types of cancer. Prof. Johnson called the results "very promising" and said that with further development "this could potentially be a test that’s done on a standard blood draw that may be part of your annual physical."
