Two keynote lectures will set the stage for contributed talks and posters by giving broad overviews of past, current and emerging microbial mats and microbialites research.

We are pleased to welcome our two eminents keynote speakers Drs. Benzerara and Des Marais:

Karim Benzerara

Monday 28th, 10 AM

Director of Research (CNRS) in Geobiology
Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie
Université Pierre et Marie Curie
4 place Jussieu
75252 Paris Cedex 05

Karim Benzerara proposes to make a synthesis of our current knowledge for biomineralization and cells encrusting processes within microbialites, both by carbonates and silicates. He will discuss the mechanisms (nucleation vs. microenvironments) implied, the laboratory manipulations and modeling as well as their transcription into the rock record, current or fossil.

David J. Des Marais
Tuesday 29th, 10 AM

Principal investigator at NASA Space Science & Astrobiology – Exobiology branch
NASA Ames Research Center
M/S 245-1
Bldg. N245,
Moffett Field, CA  94035-0001

David Des Marais will discuss how microbial mats can clarify the relationships between microbial ecosystems and the diverse biosignatures found in microbialites and other ancient deposits. These insights enhance our strategies to search for evidence of past and present life on Mars.
