Research Interests

The Rivnay group engineers organic and biohybrid bioelectronic materials, devices and systems for interfacing between the complex world of biology and traditional optoelectronics. Our interests involve understanding the unique active properties of organic (small molecule and polymeric) materials, including mixed ionic-electronic conduction and actuation and utilizing their strengths for sensing/stimulation in biomedical settings. Recent efforts include biohybrid devices that combine strengths of synthetic biology with those of bioelectronics, resulting in systems that extend what is possible in sensing and actuation/therapy. Our interests range from fundamentals of materials and interfaces to devices and systems, with applications targets in diagnostics, therapeutics, rehabilitation and regeneration of tissues.
