The Young Investigators’ Day Committee has selected BME PhD student David Herzfeld to receive the Martin and Carol Macht Award. This award is part of the 38th annual Young Investigators’ Day, where 20 graduate students and post-doctoral fellows will be honored for their research.
Herzfeld’s research describes how Purkinje cells in the cerebellum predict the speed and direction of upcoming eye movements. The researchers used a novel approach — looking at how a population of Purkinje cells change their activity in concert, rather than focusing on an individual cell. The research was done in the Laboratory for Computational Motor Control under the guidance of the paper’s co-author Reza Shadmehr, Professor and PhD Program Director of Biomedical Engineering.
The Department of Biomedical Engineering congratulates David on his excellent work and research contributions.

BME PhD student researchers Xindong Song and Yueqi Guo uncover evidence that pitch perception evolved in primate
The ability to perceive the sound quality known as “pitch” can no longer be listed as unique to humans. Research published online in the journal Proceedings of the National Academy of Sciences, entitled “Complex pitch perception mechanisms are shared by humans and a New World monkey,” infers that aspects of pitch perception may have evolved more than 40 million years — enabling the songlike vocalization by the marmoset monkey. The paper appeared on the cover of PNAS, Issue No. 3, January 19, 2016.
The Johns Hopkins research authors include BME graduate students Xindong Song (lead author) and Yueqi Guo, BME Research Associate Michael Osmanski, and Professor of Biomedical Engineering, Xiaoqin Wang.
Building on Dr. Wang’s previous research previous research that revealed regions in the marmoset brain responded to pitch in a way similar to that the human brain, the research team focused on finding behavioral evidence of pitch perception. Through a series of hearing tests, with waterspout licks as a readout, Wang’s team, led by graduate student Xindong Song, determined that marmosets share the three specialized features of pitch perception once thought to be unique to humans.

Parikh, a PhD candidate in biomedical engineering at Johns Hopkins University, has been presented with a Roche/ARCS Scholar Award at a reception at the National Academy of Sciences in Washington, DC. This is the second year that he has received the award.
An entrepreneur as well as a scientist, Kunal Parikh has spent years developing drug-delivery platforms to improve patient treatment. He plans to spend the next year pursuing patents for these technologies; submitting his research for publication in scholarly journals; visiting hospitals and manufacturing plants to conduct implementation research; and continuing to lead and mentor the team of scientists, engineers, and clinicians who work alongside him.
His research focuses on developing technologies that improve the delivery of vaccines and medicine in the body. This approach includes creating technology capable of sustained drug release to parts of the body and a platform for effective and safe gene delivery that could be used to treat or prevent infectious diseases.

Hermenegild J. Arevalo, a postdoctoral Fellow in the Natalia Trayanova’s Computational Cardiology Laboratory, has won a 2015 Young Investigator Award at the Heart Rhythm Scientific Sessions in Boston. Arevalo was given this award for his clinical research, “Virtual Electrophysiological Study Improves Risk Prediction of Adverse Cardiac Events in Post-Infarction Patients.”
Trayanova commented: “This is a breathtaking achievement, in a meeting of 12,000 people. Hermenegild was first selected as one of the 6 finalist in the Young Investigator Award, which represent 1.6% of the submissions for the award. Hermenegild then delivered a perfect presentation with amazing slides. What is particularly astonishing is that he is the winner in the clinical category, based on our first translation of cardiac simulations to the clinic, using a cohort of 32 patients. I have never been more proud!”

John Issa, BME MD-PhD student, was awarded the inaugural David Yue Award at the 2015 Johns Hopkins Young Investigators Annual Celebration. For his research project, John mapped the auditory system in the brain to see which neurons in the brain lit up when an animal processed sounds from its environment. He set up a way to watch individual neurons fire in a mouse that was awake. The David Yue Award was named after his late mentor who passed away unexpectedly in December.
Said John of his mentor: “He was not only a great scientist and a passionate teacher, but also someone who cared immensely about his students and their success. . . . For that reason, there is some solace in receiving this award, knowing that no one was as happy and proud to see their students do well as David Yue.” John will graduate in May from the M.D.-Ph.D. program and will continue working on his research at Johns Hopkins in the lab of co-advisor Eric Young.

Hermenegild Arevalo, a postdoctoral fellow in the lab of Natalia Trayanova, Murray B. Sachs Professor of Biomedical Engineering and the Institute for Computational Medicine, received a merit award in the poster competition at the 2015 Gordon Research Conference on Cardiac Arrhythmia Mechanisms held in Lucca (Barga), Italy in March. Hermenegild’s poster was entitled “Virtual electrophysiological study improves risk prediction of adverse cardiac events in post-infarction patients.”
Hermenegild’s research aims to translate computational tools into clinically utility. His approach utilizes simulations with patient-specific computer models to predict the susceptibility of patients to lethal arrhythmias. This methodology provides a non-invasive, safe, and accurate way to identify patients that could benefit from prophylactic implantable cardioverter defibrillators.

Eran Ukwatta, a second year postdoc in Dr. Natalia Trayanova’s Computational Cardiology Laboratory, won first prize for scientific poster at the 13th Imaging Network Ontario Symposium held in Ontario, Canada March 30–31, 2015. Eran’s poster, entitled “Image-based Personalized Analysis and Modeling of Cardiac Structure and Function: A Robust Method for Automatic Left-Ventricular Infarct Segmentation” was awarded based on scientific quality, structure and organization of the presentation.
Eran’s research is driven by the emerging need for robust image processing methodologies for patient-specific analysis and modeling of cardiovascular structure and function from medical images. Ukwatta’s presentation detailed development of an algorithm to segment infarct regions of a diseased heart from magnetic resonance imaging for personalized modelling of cardiac electrophysiology.
The Department of Biomedical Engineering congratulates Eran on this achievement.
