Gene Y. Fridman, Ph.D.
Principal Investigator
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.
Mohamed Rashed, Ph.D.
Post-doctoral Fellow
mrashed3@jhu.edu
Mohamed Rashed received his Master of Science in Nanotechnology from the Polytechnic of Turin, Italy. He joined multiple engineering startups for 2 years. After that, he received his Ph.D. in Electrical & Computer Engineering from the University of Louisville specializing in the design and fabrication of microfluidic platforms for cell characterization. He is currently working on the development and miniaturization of a microfluidic platform for implantable neural stimulators.
