Currently, my research focuses on how marine phytoplankton sense and respond to nutrient levels in their environment. I recently completed my PhD which investigated how algae-bacterial cocultures could be used to supply vitamin B12 to astronauts on long space missions. This was part of a wider collaboration, the MELiSSA project, or Micro-Ecological Life Support System Alternative project that aims to provide all the basic life support necessary for long-distance space exploration.
