  • Mitochondria play the central role in neuronal maintenance and survival. Biogenesis and clearance of mitochondria is delicately balanced during aging and its instability leads to cell death. The broad interest of research of this laboratory is to study form-function relationship of mitochondria in neurodegeneration and how it affects neuronal populations differentially. The specific research topics of our laboratory are:

    1. Pathways leading to mitochondrial autophagy (mitophagy) and their cross talk during aging and neurodegeneration (especially in Parkinson’s disease and Huntington’s disease).
    2. Role of mitochondrial outer membrane protein complexes to segregate and tag mitochondria for clearance.
    3. Pharmacological and genetic modulation of mitophagy: therapeutic aspects in neurodegenerative diseases.
  • This is a new laboratory. Hard working individuals with their own fellowships are encouraged to apply. Preference will be given to the candidates with experience in cell culture and animal handling.
