Here at Fridman Lab we invent and develop bioelectronics for Neuroengineering and Medical Instrumentation applications. We develop innovative medical technology and we also conduct the necessary biological studies to understand how the technology could be effective and safe for people. 

Neuroengineering Our lab is currently focused on developing the "Safe Direct Current Stimulation" technology, or SDCS.  Unlike the currently available commercial neural prosthetic devices, such as cochlear implants, pacemakers, or Parkinson's deep brain stimulators that can only excite neurons, SDCS can excite, inhibit, and even sensitize them to input.  This new technology opens a door to a wide range of applications that we are currently exploring along with device development: e.g. peripheral nerve stimulation for suppressing neuropathic pain, vestibular nerve stimulation to correct balance disorders, vagal nerve stimulation to suppress an asthma attack, and a host of other neuroprosthetic applications.

Medical Instrumentation MouthLab is a "tricorder" device that we invented here in Fridman Lab.  The device currently obtains all vital signs within 30s:  Pulse rate, breathing rate, temperature, blood pressure, blood oxygen saturation, electrocardiogram, and FEV1 (lung function) measurement.  Because the device is in the mouth, it has access to saliva and to breath and we are focused now on expanding its capability to obtaining measures of dehydration and biomarkers that could be indicative of a wide range of internal disorders ranging from stress to kidney failure and even lung cancer.


Positions in the lab are now available for postdoctoral and doctoral graduate studies in the following research areas:

Microfluidics and Electronics engineering
