Raphaelle A. Chemtob, MD, received her medical degree in 2017 from the University of Copenhagen in Denmark. As a medical student, Dr. Chemtob was academically motivated and dedicated a year to a clinical research fellowship at the Department of Cardiac Surgery in Copenhagen, Denmark. During medical school she visited Mass. Eye and Ear on an elective rotation where she developed a great interest in otolaryngology, particularly otology. After graduating, she decided to pursue a PhD focusing on superior canal dehiscence, a bony defect of the superior semicircular canal that causes debilitating auditory and vestibular symptoms. Currently, she works in the laboratories of Dr. Daniel Lee and Dr. Heidi Nakajima on basic and clinical science studies. The focus of her PhD thesis work is to determine the optimal management, diagnosis, and treatment of patients with superior canal dehiscence.

Dana Egra-Dagan, BSc Med, MA

Dana Egra-Dagan, BSc Med, MA, graduated cum laude from the Faculty of Medicine at the Hebrew University of Jerusalem, Israel, with a degree in biomedical sciences. During her studies, she spent a year working as a research assistant in the Dan Gazit Skeletal Biotech Laboratory at Hebrew University Medical School focusing on the use of stem cell and gene therapies for skeletal tissue regeneration. After receiving her degree in biomedical sciences, she decided to pursue a BA in communication sciences and disorders and an MA in audiology from Haifa University. She eventually joined the Ear and Hearing Center cochlear implant (CI) team at Bnai-Zion Medical Center in Haifa, Israel, where she worked as an audiologist for eight years. In concomitant with her work in the program, she joined Michal Luntz’s research team working on clinical projects with the focus of investigating speech in noise outcomes among variety of adult CI populations. Following a relocation to Boston, Dana joined the Dr. Daniel Lee's Lab to collect and analyze hearing outcomes in CI and auditory brainstem implants patients.

Fadhel El May

Prior to joining Dr. Daniel Lee's Lab, Fadhel worked at the Aebischer Lab at EPFL investigating novel ways of treating hearing loss with genetic editing. He worked on designing a CRISPR-Cas9 gene editing system to correct a specific gene mutation causing sensorineural hearing loss. A cochlear implant user himself, Fadhel is aspiring to tackle current auditory implants limitations and is working in the auditory brainstem implants (ABI) lab investigating novel ways of auditory nerve stimulation.

Lorenz Epprecht, MD

Lorenz Epprecht, MD, is a resident-physician in otolaryngology—head and neck surgery from Zurich, Switzerland. He joined Dr. Daniel Lee's Lab to take dedicated time off for research in the field of skull base surgery and image guided therapy. He graduated from medical school in Zurich in 2012. In parallel to his medical studies, he attended courses in neuronal network programming at the Federal Institute of Technology (ETH) in Zurich. He was supported by a national grant for high-performing students by the Swiss Study Foundation. After graduation, he trained both in neurosurgery and otolaryngology—head and neck surgery in order to become a skull base surgeon. His early publications focused on the autonomous nervous system and skull base related aneurysmal bleedings. Currently, he conducts research on advanced imaging techniques such as diffusion tensor imaging in skull base tumors and the auditory pathway in the brainstem.

Vivek Kanumuri, MD

Vivek Kanumuri, MD, is a resident-physician in otolaryngology—head and neck surgery at the Mass. Eye and Ear/Harvard Medical School. Originally from Edison, New Jersey, he graduated from Rutgers University - New Jersey Medical School in 2014 with a medical degree and was elected into the Alpha Omega Alpha honor society. During his time in medical school he also completed a prestigious Howard Hughes Medical Institute Research Fellowship where he worked on multiphoton imaging and optical manipulation of epileptic circuits under the mentorship of Dr. Rafael Yuste at Columbia University. He is currently working in the Auditory Brain Implant Lab with Dr. Daniel Lee on the development of optical neuro-prosthetics for stimulation of the auditory system as part of the T32 grant in the Eaton-Peabody Laboratories at Mass. Eye and Ear. He also has clinical interests and has published extensively on endoscopic skull base surgery and sinonasal malignancies.

Elliott D. Kozin, MD

Elliott D. Kozin, MD, graduated summa cum laude from the University of Pennsylvania with a degree in history prior to receiving his medical degree at the University of Pennsylvania School of Medicine. During medical school, he spent a year at the National Institutes of Health (NIH) in Dr. Bechara Kachar's laboratory investigating the role of non-muscle myosin II in the inner ear as part of the Howard Hughes Medical Institute Research Scholars program. As one of the seven-year research track residents at Mass. Eye and Ear/Harvard Medical School, his current research with Dr. Daniel Lee focuses on employing optogenetics to improve cochlear and auditory brainstem implant technology.

Stephen P. McInturff

Stephen P. McInturff is a graduate student in the Speech and Hearing Bioscience and Technology program at Harvard University. Upon graduating with a bachelor’s in neuroscience from The College of William and Mary in Williamsburg, Virginia, Stephen held a post-baccalaureate position at the National Institute of Deafness and Other Communication Disorders (NIDCD/NIH) under the supervision of Dr. Matthew Kelley before coming to Harvard. His current research in the Auditory Brainstem Implant (ABI) Lab is aimed at determining which neurons are stimulated in the cochlear nucleus by ABI electrode arrays and how these neurons contribute to evoked electrophysiological responses. He is also interested in how the brain adapts to hearing loss and what effects this may have for ABI recipients.

Ahad A. Qureshi, MD

Ahad Qureshi

Ahad A. Qureshi, MD, is a graduate of The Aga Khan University Medical College in Karachi, Pakistan. He decided to pursue a research fellowship at the Eaton-Peabody Laboratories to enrich his career on the path to becoming a surgeon-scientist. His previous research experience involved cross sectional work in establishing a clinical and laboratory profile of patients with cystic fibrosis in Pakistan and assessment of long-term outcomes of patients undergoing radical and modified-radical neck dissections. He has also conducted bioinformatics research on identifying conserved regions of the glucokinase enzyme of Acanthamoeba Castellani. Currently, Ahad’s primary focus is the application of optogenetics technology to cochlear and auditory brainstem implants (ABI). His is also the clinical research coordinator for the adult and pediatric ABI clinical trials for non-neurofibromatosis type 2 patients.

Osama Tarabichi, MD


Osama Tarabichi, MD, received his medical degree from the Royal College of Surgeons in Ireland-Bahrain. He developed an interest in hearing sciences early on in his medical school career and spent his summers at the Auditory Research Laboratory at St. Louis University studying oxidative stress signalling in the lateral wall of the cochlea. After graduating medical school, he decided to pursue a research fellowship at the ABI lab. His research at Dr. Daniel Lee's Lab is focused on developing a chronic mouse model of the auditory brainstem implant.
