Chao Zhou believes his work with combining imaging technologies has the potential to improve surgeries that remove malignant breast tumors. “As many as 40 percent of breast cancer patients now have to undergo a second surgery, because part of the tumor is left behind during the first,” says Zhou, an assistant professor of electrical and computer engineering. By combining two technologies -- optical coherence tomography (OCT) and confocal microscopy -- Zhou says doctors can more precisely pinpoint a tumor’s location and remove it entirely on the first try. Before joining the faculty in June, Zhou was a senior postdoctoral associate at the Massachusetts Institute of Technology, where he pioneered the use of OCT in cancer detection. He received a Pathway to Independence research award in 2011 from the National Institute of Biomedical Imaging and Bioengineering in the National Institutes of Health.
