The Chen lab develops high-channel-count, chronically implantable devices to record from and stimulate the brain. We harness cutting-edge developments in electrode fabrication and microelectronics to improve probe durability and biocompatibility, generating fundamental neuroscientific knowledge and translating results from the lab to the clinic.
