Melissa Project, ESA
Synthetic Ecology
I am a first year PhD student in the Department of Plant Sciences at the University of Cambridge. My project focuses on the use of synthetic ecology for sustainable vitamin production for human consumption on long Space missions. I am part of the MELiSSA project, with the ESA, looking at developing a closed-loop life support system for astronauts. The MELiSSA loop is broken down into 4 compartments and my work focuses on compartment 4A, the photoautotrophic bacteria. I am also researching the interactions between eukaryotic algae and bacteria, with focus on vitamin B12 exchange.
