Gene Y. Fridman, Ph.D.
Professor of Otolaryngology HNS and Biomedical Engineering
gfridma1@jhmi.edu
Dr. Fridman is a Biomedical and Electrical engineer. After receiving his Master of Science in Electrical Engineering from Purdue University in 1995, he worked in the aerospace and then the biomedical industry for five years as a software and systems engineer before deciding to engage in an academic career. He received his Ph.D. in Biomedical Engineering specializing in neural recording and stimulation and micro-electro-mechanical systems (MEMS) from UCLA in 2006. Since 2000 he has held an on-going consulting and collaborative relationship with biomedical engineering companies in research and design of neural stimulation and recording devices. He contributed to research and development of spinal cord, retinal, cortical, cochlear, and vestibular neural implants.

Celia Fernandez Brillet

Ph.D. Student in Biomedical Engineering
Celia Fernandez Brillet is a Ph.D. Candidate in the Department of Biomedical Engineering at the Johns Hopkins University School of Medicine. In 2020, she completed her BS in Biomedical Engineering at Universidad Carlos III de Madrid (Spain), where she graduated with honors at the top of her class and School of Engineering. Additionally, she spent several months studying at other universities around the world sponsored by academic excellence scholarships, including Stanford University, Imperial College London, University of Maryland, and Vrije Universiteit.
​
Celia is passionate about bridging the gap between medicine and engineering. She is especially interested in the design of medical devices to interface with the nervous system. In the lab, she is working on extending the functionality of vestibular implants by testing the safety of chronic DC stimulation and exploring stimulation of the otolith end organs. She is also involved in the human clinical trial.

Evan Vesper
Ph.D. Student in Biomedical Engineering
Evan Vesper received his Bachelor's degree in Electrical Engineering at Case Western Reserve University and is currently a PhD student in Biomedical Engineering at Johns Hopkins University.
He is passionate about improving interfaces with the nervous system and improving rehabilitation technologies. He currently works on exploring how SDCS interacts with the vestibular system. Evan also works on the vestibular implant clinical trial.

Runming (Tony) Wang
Ph.D. Student in Biomedical Engineering
Runming (Tony) Wang is a Ph.D. student in the Department of Biomedical Engineering at the Johns Hopkins University School of Medicine. He graduated with honors from Emory University in 2023, earning a Bachelor of Science degree in Neuroscience and Behavioral Biology. Tony's research interests are deeply rooted in the exploration of neural interfaces and their dynamic interactions with brain activity.
​
In his current research, Tony focuses on the precise modulation of rodent cortical activity using invasive ionic direct current (iDC) stimulation. This work aims to expand the existing understanding of how iDC can be strategically utilized to influence cortical network dynamics, potentially paving the way for novel therapeutic strategies for neurological disorders.
