Biomedical devices have enabled a revolution in medicine from research to diagnosis to treatment. In fact, the future of medicine is nothing but bright, with devices that will diagnose and treat diseases not only from outside but from inside the body, addressing localized malfunction in neurological, cardiovascular, autoimmune, cancer and other diseases. Such advanced technology requires miniaturization of implantable medical devices with a seamless integration of electronics and biology. In this vision, I am interested in using fundamental concepts from physics, biology and medicine to develop novel highly-integrated micro-systems that enable the next generation of medical technology.

The path towards the miniaturization of bioelectronics requires not only a reevaluation of existing paradigms but also an exploration of advanced IC processes and the hybrid integration of ICs with new materials, MEMS technology, and biological and chemical sensors and actuators. The transition to nanometer processes imposes new constrains for the design of analog circuits such as lower supply voltages and higher process variation, in applications that require low power solution in a small form-factor. Novel circuit techniques such as digitally-assisted analog circuits, self-healing circuits and 3D integration are just some new approaches that can be beneficial for implantable medical devices.


  • ATOMS: Minimally-Invasive Biological Interfaces
  • Study of techniques, approaches and opportunities for integrated circuits in biological interfaces using biophysical methods such as magnetic resonance, ultrasound and infrared light.

  • Retinal Prosthesis
  • Most progressive vision loss occurs when the first layer of the retina (the photoreceptors) is damaged. Retinal prostheses aim to restore vision by bypassing the damaged photoreceptors and directly stimulating the remaining healthy neurons. Our approach uses highly scaled technologies to reduce area and power, and to support hundreds of channels for fully intraocular implants.
