By fusing light sensors with endogenous protein sequences serving as targeting motifs, we can selectively express photoreceptors at various locations within the cell. In our research, we are specially interested in the pH and voltage regulation of subcellular organelles. The importance of these processes for cellular aging, the onset of neurodegenerative diseases like Parkinson or Alzheimer's, as well as the proliferation of carcinomas, can be more precisely explored through the engeneering of new optogenetic tools and may inspire new therapeutic approaches..
