Mengdi Han Research Group

Our Mission
Our group aims to develop and build bioelectronics with 3D architectures. The resulting 3D bioelectronics can form conformal interfaces with soft, curvilinear biological tissues, and enable new modalities in diagnosis and therapy. We exploit these 3D bioelectronic devices and systems as tools to understand fundamental biological questions and improve human health.
Open Positions
We are looking for talented and motivated postdoctoral fellows, Ph.D. students, and undergrads to join us. Click HERE for details.
