Meet a Microbiologist: Raphael Laurenceau
Chemical engineer turned microbiologist. Co-founder and co-organizer of a DIY biolab. Cultivator of photosynthetic bacteria. Raphael Laurenceau began his path in the sciences by studying chemical engineering. After watching several nature documentaries (thanks David Attenborough), he soon realized he was in the wrong field. There were too many fascinating things happening in the world’s ecosystems and Raphael wanted to study them. Though life is all chemistry, he wanted to study biology and used his chemistry background to leverage a career in biology. “I realized that chemistry is a great stepping stone to enter the world of biology. There is nothing more than chemical reactions happening inside cells,” Raphael says.

The Unseen Cloud Makers from the Ocean

The ocean is teeming with microscopic life that despite their minuscule size, greatly impact our world's ecosystem and climate. A large majority of these organisms are considered planktonic, those that are suspended in the ocean waters and rely on the current for movement. Phytoplankton are a type of plankton that are autotrophic and use just photosynthesis as a carbon source. Not only do they serve as a food source for larger organisms, phytoplankton also produce the majority of the world's oxygen and also play roles in cloud formation. (more…)
