Oxygenic photosynthesis, history of photosynthesis research, and photosynthesis education
Biophysical, biochemical, physiological and historical aspects of oxygenic photosynthesis; photochemistry and biophysical chemistry of reaction center chlorophyll a-complexes and of intact photosynthetic systems; mechanisms of primary photochemical events and oxygen evolution; pathways of electron and proton transport. Current research involves collaborative work with many laboratories in the World (including those at University of Illinois at Urbana-Champaign; University of Hyderabad, India; Jawaharlal Nehru University, India; Institute of Microbiology, Trebon, The Czech Republic, and Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE), México).
