Researcher Ram Dantu, professor of computer science and engineering, is putting life-saving technology in the hands of 911 callers. Dantu's National Science Foundation-funded research uses smartphone technology to virtually place 911 operators at an emergency scene, helping them gather the most accurate information to assist victims and 911 callers trying to help them. Working with a team of researchers, Dantu developed smartphone software that can allow an operator to gauge a victim's breathing, heart rate and blood pressure remotely. The software also allows 911 operators to control smartphone cameras so they can view an emergency scene, as well as give instructions for administering CPR.
