Hossack lab has a new Coulter Partnership Award of $136,00 for the design of a therapeutic ultrasound approach for the treatment of degenerative heart valve disease. The Principal Investigators are: John A. Hossack, Biomedical Engineering and Patricia Rodriguez Lozano, M.D., Cardiovascular Medicine. Clinical Co-Investigators include: Austin Robinson, M.D., Mohamed Morsy, M.D., and Christopher Kramer M.D., Cardiovascular Medicine and Radiology. New designs will be developed using Finite Element Analysis to evaluate technical tradeoffs.

"Enhanced visualization of ultrasound contrast agents using normalized singular spectrum area and singular value thresholding"
Elizabeth Herbst has won a poster award at the annual European Symposium on Ultrasound Contrast Imaging, a top level inernational meeting in the field of ultrasound contrast. Her presentation for was chosen among a group of 16 presenters in ultrasound contrast imaging. Co-authors on the work include Dr. John Hossack, Dr. F. William Mauldin, and Dr. Alexander Klibanov.

Congrats to Yanjun, Feifei and Elizabeth authors of the lab's four most recent publications:
Yanjun Xie for "Real-time control of microbubble diameter from a flow-focusing microfluidic device" (a conference paper in IEEE International Ultrasonics Symposium).
Yanjun Xie for "Closed-loop feedback control of microbubble diameter from a flow-focusing microfluidic device" (Journal paper in Biomicrofluidics).

Hossack Lab has been awarded $97K from the UVA-Coulter Partnership for "Super resolution molecular imaging for improved prostate cancer diagnostic performance." Our proposal addresses new methods of ultrasound parameter setting and signal processing to yield approximately five fold improvement in resolution for ultrasound imaging combined with imaging of molecular signature of cancer.

Elizabeth Herbst has won an American Heart Association Pre-Doctoral Fellowship! Her project focuses on the use of ultrasound molecular imaging to characterize the aneurysmal abdominal aorta.

In Vitro Sonothrombolysis Enhancement by Transiently Stable Microbubbles Produced by a Flow-Focusing Microfluidic Device

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.

The second annual Athanasiou ABME Student Award Session will be held at the 2019 BMES Annual Meeting. Just six awardees have been selected from all papers first-authored by students and postdocs in 2018 in the Annals of Biomedical Engineering. Hossack Lab's Adam Dixon (PhD '16) is one of the six.

The World Molecular Imaging Society (WMIS) has awarded Elizabeth the Women In Molecular Imaging Network (WIMIN) Award and a student travel stipend for the upcoming World Molecular Imaging Congress (WMIC). She was selected for both awards based on the scientific merit of her submitted abstract.From the WMIC Website:
