What is Photobiology?

Photobiology is the biological study of the interactions of light with living organisms.

Photobiologists may specialize in the study of photosynthesis, vision, circadian rhythms, bioluminescence, ultraviolet radiation effects, photodynamic therapy, and other fields. The five divisions of the American Society for Photobiology (ASP) reflect the diversity and inter-disciplinary nature of photobiology.

ASP Divisions
1. Photochemistry, Photophysics and Phototechnology
2. Photosensory and Circadian Biology
3. Photosynthesis, Bio- and Chemiluminescence
4. Photomedicine
5. Environmental Photobiology and UV Effects

American Society for Photobiology
