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 (PSI) and other membrane complexes in higher plant chloroplasts. We solve the structure of plant PSI super-complex including its four light-harvesting complexes at 2.6 Å resolution. We intend to obtain atomic resolution of plant PSI.

- Structure, function and molecular biology of cyanobacterial photosystem I. We solve the structure of a trimeric PSI from synechocystis at 2.5 Å resolution.

- Crystal structure of photosystem I from the red algae Cyanidioschyzon merolae.

- Expression and structural determination of marine viruses-encoded membrane proteins.

- Harnessing Oxygenic Photosynthesis for Sustainable Energy Production.
