Oded Béjà is best known for discovering the first bacterial rhodopsin[2] naming it proteorhodopsin,[3] during his postdoctoral fellowship in the laboratory of Edward DeLong. Oded Béjà's laboratory focuses currently on the role and diversity of photosynthetic viruses infecting cyanobacteria in the oceans,[4] and the use of functional metagenomics for the discovery of new light sensing proteins.
In 2018, the team of Oded Beja discovered a new family of rhodopsins with an inverted membrane topology, which can be found in bacteria, algae, algal viruses and archaea.[5] Members of the new family were named heliorhodopsins.[5]
