LATEST PROJECTS
Wireless Microdevices​
​
The major goal of this initiative is to develop the next generation of brain stimulation devices for understanding and treating mental health illnesses and brain disorders. This project seeks to develop chronic ultra-small microdevices which are minimally-invasive, wireless, battery-less, and injectable. These devices are distributed across the brain to form a wireless network system for precise neural modulation.

Transcranial Magnetic Stimulation​
​
Non-invasive deep brain stimulation has been a major challenge in the field of neuroscience for the past three decades. This project seeks to develop a radically new brain stimulation technique based on temporal interference of two high-frequency sinusoidal magnetic fields. This novel brain stimulation technique, called magnetic temporal interference (MTI), can non-invasively focus a small-size magnetic or electric field beam at any depth inside the brain and stimulate the deep brain area with a high resolution without impacting the superficial regions.

Micro-magnetic stimulation​
​
The goal of this project is to develop efficient micro-magnetic stimulation probes that could potentially replace conventional electrode-based stimulation devices for chronic applications. The key point about micro-magnetic stimulation is the fact that the micro-coils are encapsulated with a biocompatible material and therefore avoid direct contact with the tissue, unlike electrode-based stimulation devices. Therefore, micro-magnetic stimulation efficiency does not decrease over time.
