Acid-Sensing Ion Channels (ASICs) play central roles in chronic pain and other acidosis-related pathologies. The focus of my research is to dissect their physiological and molecular function in neurons, muscle and the intestine and how mutations in these channels affect behaviour and metabolism. I use Two-Electrode-Voltage Clamp (TEVC) in Xenopus oocytes for characterising these ASICs in vitro. And in order to investigate and dissect physiological processes in vivo, I use the 1 mm long transparent nematode C. elegans which present an excellent model organism for a systems-level understanding of genetics, physiology and behaviour due to its complete connectome, vast behavioural repertoire and due to its transparency physiological processes can be easily observed in real time using optical indicators.
