Research profile

We study olfaction in a nematode called Caenorhabditis elegans. The nervous system of the nematode works in a manner similar to larger animals including humans. We study olfaction in this worm by utilizing genetic, genomics and optogenetic tools. We are interested in studying causation of anosmia (loss of sense of smell) in C. elegans using our expertise. Anosmia is common in many viral infections including COVID-19 as well as in metabolic disorders linked to anorexia.
