Diane Dalecki Elected Vice Chair AIUM Bioeffects Committee
Diane Dalecki (BME) has been elected Vice Chair of the Bioeffects Committee of the American Institute of Ultrasound in Medicine (AIUM). Professor Dalecki is a Fellow of the AIUM, and Director of the Rochester Center for Biomedical Ultrasound (RCBU). The Bioeffects Committee provides information and guidance to the AIUM on matters relating to the biological effects and safety of ultrasound. In addition to the 14 elected AIUM members, the committee includes select resource members from federal agencies and external organizations. Following completion of a 2-year term as Vice Chair, Professor Dalecki will become Chair of the Bioeffects Committee. Professor Dalecki served previously as Chair of the Bioeffects Committee from 2001-2003. The AIUM is a multidisciplinary association of more than 9000 physicians, scientists, engineers, and clinicians dedicated to advancing the safe and effective use of ultrasound in medicine.

Emma Grygotis Wins Outstanding Presentation Award
Emma Grygotis receiving her Outstanding Presentation Award at the 2015 Therapeutic Ultrasound Winter School. Shown (Left to right) are conference organizers Gail ter Haar and Vera Khokhlova, and Emma Grygotis.
Emma Grygotis was the recipient of an Outstanding Student Presentation Award at the 2015 Therapeutic Ultrasound Winter School held in Les Houches, France at the École de Physique des Houches. At this forum, held in the French Alps on March 8-13, 2015, a group of twenty professors and fifty students gathered from around the world to discuss a range of topics in the rapidly expanding field of therapeutic ultrasound. Emma presented an overview of her studies focused on developing ultrasound technologies to fabricate bioactive collagen hydrogels for wound repair.
Attendees of the 2015 Therapeutic Ultrasound Winter School in the French Alps in Les Houches, France.
Emma is a second year graduate student in Pharmacology and Physiology working with Professor Denise Hocking (Pharmacology and Physiology, BME) and Professor Diane Dalecki (BME) on a joint collaboration to develop ultrasound technologies for tissue engineering and regenerative medicine. Emma is currently a pre-doctoral fellow in the HHMI Med-into-Grad program, and also a student member of the Rochester Center for Biomedical Ultrasound (RCBU). Recent BME alumna Karla Mercado, Ph.D. was also a participant at the 2015 Therapeutic Ultrasound Winter School.

BME Senior Design Team Focuses on Ultrasound Project
BME seniors help real-life customers solve biomedical engineering problems through the two-semester Senior Design course taught by RCBU member Amy Lerner and Scott Seidman. In the 2014-2015 academic year, one team of BME seniors is embarking on a project to develop an ultrasound-based technique to detect dentinal cracks in teeth. The team will focus on detection of cracks in mandibular molars, as these are the teeth that exhibit cracks often. The senior design team consists of BME students Alexa Kuenstler, Jonathan Macoskey, Jacob Hyatt, Tek Gautum, and Jenny Won. Long-standing RCBU member Robert Lerner, MD who serves as the customer for this project brought the problem to the team. Diane Dalecki, Ph.D. is the senior design team supervisor for this project.

John Cormack visits RCBU
John Cormack returned to Rochester and presented a lecture for the RCBU titled
Propagation of plane nonlinear shear waves in soft solids.John is a 2014 UR alumnus and is currently a graduate student at UT Austin working with Professor Mark Hamilton in the Applied Physics Laboratory. John's presentation to RCBU members provided an analytical approach to modeling the nonlinear propagation of shear waves in soft biological materials. While at the UR, John conducted research with Professor Sheryl Gracewski (ME) and Professor Jong-Hoon Nam (ME, BME).

Remembering Ultrasound Pioneer Floyd Dunn
The biomedical ultrasound community sadly lost one of its important pioneers. Floyd Dunn passed away on January 24, 2015 at the age of 90. Floyd was a member of the Electrical and Computer Engineering Department at the University of Illinois at Urbana-Champaign for over 50 years. Following the death of Bill Fry in 1968, Floyd became director of the Department’s Bioacoustics Research Laboratory and made it a world leader in the field of biomedical ultrasound. Founding RCBU Director Ed Carstensen writes,
It is hard to believe today, but in the mid-1960s, research in this field had dwindled to the point that progress could be reported in biannual sessions at meetings of the Acoustical Society. Floyd and Wesley Nyborg organized those special sessions and we are uniquely indebted to them for keeping the field alive.
Floyd's body of scientific work provides foundation for our understanding of the propagation of ultrasound in tissues and the biological effects of ultrasound. He was a member of both the National Academy of Sciences and the National Academy of Engineering, and served as President of the Acoustical Society America. He was recognized with the highest awards from numerous scientific societies, including the IEEE Edison Award, the ASA Gold and Silver Medal Awards, and the AIUM Joseph P. Holmes Basic Science Pioneer Award. He served on many FDA, NIH, AIUM, and ASA committees, and was a member of Committee 66 of the National Council on Radiation Protection.
Floyd was a Charter Honorary Member of the RCBU and was a long-time friend and colleague for many of us. The RCBU and the wider biomedical ultrasound community will miss Floyd dearly.

New Study Probes Link Between HIV Drugs and Vascular Disease
RCBU Faculty member Marvin Doyley, Ph.D., is a part of a multidisciplinary team that was recently awarded a $3.8 million grant from the National Institutes of Health to better understand why individuals who receive anti-retroviral treatment for HIV are at greater risk for heart disease and stroke.
The study will use a new ultrasound technology developed by Professor Doyley's group for one of the key measurements in the study -- tracking the thickness and stiffness of the carotid artery. Read more about the project here.
