Badger Group - Photosynthetic functional genomics

My group is focused on understanding the ways different photosynthetic organisms have adapted their photosynthetic biochemistry and physiology to efficiently fix CO2 in environments where CO2 is a limiting substrate. This includes interests in the biochemical deficiencies of Rubisco (where I started in my PhD), how organisms have developed CO2 concentrating mechanisms (my first postdoc) to overcome these limitations, and how the biochemical pathway of photorespiration deals with the waste products of the Rubisco interaction with O2. We use organisms ranging from cyanobacteria and algae up the plant model systems such as Arabidopsis, spanning different evolutionary scales of photosynthetic development.
