This is a list of researchers that I know are doing photochemistry type of research. I have also included some of their main areas of focus as well. By no means is this a definitive list of all the researchers. The initial list is of researchers at DTU physics, while the second group is external researchers. The external researchers first in terms of approximate experience in the field, and secondly by location. If you are aware of any researcher that has moved or shifted their focus, feel free to let me know and I will modify the list as needed.
