Research Interests

Our lab concentrates on the study of membrane-proteins. We study the molecular mechanisms involved in transport and energy transduction. The five main subjects that we are currently engaged in are:

  • Structure, function and molecular biology of photosystem I and other membrane complexes in higher plant chloroplasts. We solve the structure of plant PSI super-complex including its four light-harvesting complexes at 3.1 Å resolution. We intend to obtain atomic resolution of plant PSI.
  • Structural determination of super-complexes in biological membranes. Crystal structure of PSI-ferredoxin, PSI-plastocyanin, PSI- cytochrome b6-f etc.
  • Crystal structure of chloroplast photosystem II and ATP-synthase.
  • Expression and structural determination of marine viruses-encoded membrane proteins.
  • Harnessing Oxygenic Photosynthesis for Sustainable Energy Production.
