Hossack Lab grad students Elizabeth Herbst and Yanjun Xie presented their research at the 2019 IEEE International Ultrasonics Symposium in Glasgow, Scotland. Yanjun's research focused on designing a feedback control system on the diameters of microbubbles produced by a flow-focusing microfluidic device. Elizabeth's research was focused on the use of normalized singular spectrum area to isolate unique signals from ultrasound contrast agents.
