Pu Wang, a post doctoral researcher at the Purdue University Weldon School of Biomedical Engineering, has been named a finalist in the 2016 InnovateHER Business Challenge by the U.S. Small Business Administration. Wang is co-founder of Vibronix Inc. with Ji-Xin Cheng, professor of biomedical engineering and chemistry. Wang was selected for his MarginPAT innovation; MarginPAT is an intraoperative assessment of breast tumor margin using a photo acoustic/ultrasound imaging system. The system provides a shorter procedure time, allowing a surgeon to clear cancer residue after removing a tumor from a breast cancer patient, which reduces the chance for a second surgery.
