The Kralj lab works to create new tools to study functions of molecules, cells, and organisms. A long-standing goal in biology is to develop a genetically encoded reporter of membrane voltage. Such a reporter would eliminate the requirement for cellular mechanical contact, and greatly expand the scope of potential experiments. Microbial rhodopsins have recently gained interest as sensitive and fast fluorescent voltage indicators, and are being used to rapidly measure electrophysiology from many biological systems, including some that are un-patchable.
