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.

- Cryo-EM structure of photosynthetic membrane complexes. We solved the structure of over 20 photosynthetic membrane complexes at near atomic resolution.  

- Structure, function and mechanism of photosystem II. We solved the structure of PSII from various green algae and suggested a novels mechanism for plastoquinone photoreduction.

- Harnessing Oxygenic Photosynthesis for Sustainable Energy Production.
