The OEPC is a device which transduces optical pulses to ionic displacement currents in the surrounding electrolyte. 


The OEPC device can be integrated onto thin plastic cuffs which can be implanted and fixed around peripheral nerves. Using tissue-penetrating deep red and infrared wavelengths, the implants can be actuated, in order to get long-term chronic stimulation in animals. doi:

Photo(electro) faradaic devices

Catalytic reactions with organic semiconductors. At the basic level, we are always fascinated with electro- and photo-catalytic reactions occurring at the interfaces of organic semiconductors and aqueous electrolytes. Such questions are of broad interest, ranging from biochemical/physiological phenomena to industrial chemical processes. In particular, we strive to have world-class know how on oxygen reduction chemistry in the context of organic electronic materials.
