Research Interests

Dr. Samo is interested in applying principles of microbial ecology toward addressing questions and challenges in bioenergy and geochemistry. His current work aims to understand the influence of algal-bacterial interactions on elemental cycling and how this knowledge can be applied toward bioenergy applications and ecosystem functioning. He combines experimental culturing and manipulation of microbial communities with measurements of single-cell activity and metabolite transfer between and among microbes.
