Research Expertise
Description
Research interests My laboratory is interested in understanding molecular and circuit mechanisms of simple learned behaviors. We use the genetic model organism Drosophila melanogaster to study fundamental synaptic mechanisms as well as mechanisms of simple olfactory memory. An obvious extension of these studies to ask how these mechanisms are affected in disease and we currently study disease models for fragile-X mental retardation and spinocerebellar ataxia. Five post-doctoral researchers and three postgraduate students in my lab use many in vivo approaches including Drosophila genetics, two-photon microscopy based live-brain imaging, electrophysiology, and a range of cell biological, behavioral & molecular techniques. Several collaborations, particularly with top research groups in India and the US, expand our work into other fields such as natural products and peptide neurotoxins. Recent advances in the lab include the following. 1. Primarily in collaboration with Veronica Rodrigues' group in the NCBS, Bangalore, we have discovered that gene expression- and synaptic growth dependent potentiation of GABAergic neurons drives specific forms of learned olfactory behavior. 2. In collaboration with Roy Parker at the University of Arizona, we have found that that proteins and mechanisms that control translation of mRNAs in yeast, also regulate the translation of mRNAs stored in synapses. Some of these regulatory mechanisms, required for proper neuronal homeostasis/plasticity are required for miRNA function and altered in human neurological disease.Projects
