Nicolas Valentin MS

Nicolas Valentin completed a Master's Degree in the department of Biomedical Engineering at Johns Hopkins University in 2012. At VNEL, his research focused on determining whether a commercially available cochlear implant stimulator could be adapted for use as a vestibular implant. The prototype vestibular implant system resulting from his work became a basis for the MVI(TM) multichannel vestibular implant now being evaluated in a first-in-human trial at VNEL.

Prior to joining VNEL, he received his undergraduate degree in Electrical Engineering from the California State Polytechnic University, Pomona, with emphasis in control & robotics, communications & signal processing, and instrumentation. He also completed the Post-Baccalaureate Research Education Program (PREP) in biomedical engineering at Johns Hopkins, during which he worked as a research technologist in the Neuroengineering and Biomedical Instrumentation Lab under the guidance of Dr. Nitish Thakor and Dr. Xiaofeng Jia. His main research project there focused on the study of therapeutic hypothermia after cardiac arrest. In a parallel project, he investigated the neurological changes resulting from septic encephalopathy and explored potential methodologies for early diagnosis, treatment and prognosis.

Since 2012, Nic has been a System Engineer at Labyrinth Devices, LLC, a medical device company dedicated to helping people living with vestibular disorders, by bringing vestibular implant technology and improved vestibular diagnostic systems into clinical practice.
