The Nano-Cybernetic Biotrek (NCB) research group is an adventurous scientific voyage, fusing engineering, applied physics, and biology to bridge the gap between nanotechnology and synthetic biology.

The group’s two major research directions are to :

  • develop novel nanoelectronic devices ( such as  Spintronics, Neuromorphic) employing ingenious device physics and smart nano-materials to achieve extreme energy efficiency, scalability as well as massive reduction in Green House Gas emissions  for sustaining the growth of Artificial Intelligence;
  • merge such next generation technologies with living-matter creating unique nanomachine-bio hybrid systems, with remote control and wireless communication abilities to achieve unprecedented possibilities for probing/sensing and modulating (for therapeutics) our brain. Our lab builds radical neurotechnologies for treating diseases such as cancer, pain and neurodegenerative diseases including Alzheimer's disease

The long-term goal of the group, going beyond probing and modulation, is to enable incorporation of functionalities, not otherwise allowed by biology, for enhancing and transcending us beyond our biological limitations.
