Himanshu Shekhar Awarded ASA Hunt Fellowship

November 13, 2014

Himanshu Shekhar, who received his Ph.D. in May of 2014, has been awarded the very prestigious Frederick V. Hunt Postdoctoral Research Fellowship in Acoustics from the Acoustical Society of America for 2015-2016. Himanshu completed his doctoral work in Prof. Marvin Doyley’s group, working on high frequency ultrasound imaging. The Hunt Fellowship was established by the Acoustical Society of America to honor the legacy of the late Prof. Frederick Vinton Hunt of Harvard University. Himanshu received one of two Hunt fellowships which were awarded this year for his proposal titled “Ultrasound-enhanced drug delivery for treating vascular disease.” He will complete this research in the Department of Internal Medicine at the University of Cincinnati, working with Prof. Christy Holland. Congratulations Dr. Shekhar!

Verma and Fernandes Accepted into HHMI Fellowship

July 29, 2014

Prashant Verma (Physics) and Ninoshka Fernandes (BME), both Ph.D. candidates advised by Prof. Marvin Doyley, have been accepted into the Howard Hughes Medical Institute (HHMI) Med-into-Grad Fellowship in Cardiovascular Science. This prestigious HHMI sponsored URMC fellowship augments traditional Ph.D. training with clinical rotations, a clinical co-mentor, a weekly Cardiovascular Research Institute seminar series, and translational cardiovascular coursework to train the next generation of bench-to-bedside cardiovascular scientists. Prashant received the fellowship based on his application titled, "Using plane wave elastography to estimate the viscoelastic parameters of the vascular tissue." Ninoshka received the fellowship based on her application titled, "Intravascular ultrasound (IVUS) imaging of inflammation and angiogenesis targeted contrast agents to characterize plaque development and vulnerability in atherosclerosis". Congratulations to Prashant and Ninoshka!
