There will be two Keynote Speakers, one on Sunday afternoon, and the other on Wednesday afternoon.

  1. Phylogeny, Taxonomy and Evolution (Chairs, S. Crowe and V. Yurkov)
  2. Environment and Ecology (Chairs, A. Poulain and A. Lang)
  3. Physiology, Metabolism and Sensory Transduction (Chairs, T. Hanson and G. Owttrim)
  4. Bioenergetics, Natural and Artificial Photosynthesis (Chairs, D. Bryant and T. Beatty)
  5. Biotechnology and Synthetic Biology (Chairs, C. Kerfeld and D. Bhaya)

Each session will be chaired by one of the LOC as noted above. All sessions have 3 to 4 “Plenary” speakers who will be given 30 min (25 + 5 min for questions). Some sessions may extend over more than one day. The remainder (50 to 60) of the oral presentations of 20 min (15 + 5 min for ques) will be chosen from the submitted abstracts by the session chairs.

Posters will be displayed in atriums adjacent to the lecture halls, from Sunday night to Thursday morning. Even number poster presenters attend the Monday poster session, and odd numbers on Wednesday.
