Natan Davidovics, PhD

Natan Davidovics completed his doctoral degree in the department of Biomedical Engineering at Johns Hopkins University in March, 2012. He received his undergraduate degree in Biomedical Engineering from Rutgers University in 2005 with a focus on neuroscience and electrical engineering. His research background includes a wide range of neuroengineering projects including neural decoding for an EEG-controlled prosthetic hand, EEG-fMRI brain-computer interface, micro-electrode array fabrication for single-cell recording in rats, deep-brain stimulation for treatment of Parkinson's disease, and others. His PhD research focused on improving the communication between the vestibular prosthesis and the brain in animals with vestibular dysfunction. He is also the founder and editor of a weekly neuroengineering newsletter NEWRON (NeuroEngineering Weekly Review of the News). From 2012-2015, he was a systems engineer at Labyrinth Devices, LLC, a start-up company focused on helping to bring JH-VNEL technologies through the commercialization and regulatory processes required to make them accessible to patients. Since 2015, he has been a Product Development Manager at GluSense, a medical device company that produces implantable glucose sensors for use in closed-loop control of insulin pumps.Peer-Reviewed Publications:
