Concussion Detecting Laser

Tianqu Zhai, EECS PhD Student, participates in an experiment testing a laser designed to detect concussions in the Center for Human Growth and Development at the University of Michigan in Ann Arbor, MI on January 30, 2020. The laser light runs through fiber optic cables attached to the forehead. The light collected by the probe enables researchers to look at tissue oxygen and cell metabolism at the same time. This could lead to a fast and noninvasive way for doctors to monitor the health of brain cells. The collaboration on the project includes Mohammed Islam, EECS Professor; Rachel Russo, House Officer, Surgery at University of Michigan Hospitals; Ioulia Kovelman, Associate Professor of Psychology; and Steven Broglio, Professor of Kinesiology, School of Kinesiology.
