I was awarded my PhD at Lund University in 1967; my thesis dealt with the effects of light on plastid differentiation in plant roots. I think that it was my father who put me on the biology track, mostly by showing me small animals and what they are up to: ants, ant lions, Daphnia etc.
Mostly, I am driven by curiosity, but now and then I have had practical goals in sight: saving the ozone layer, finding a way of early detection of plant disease, finding a recipe for optimum exposure to sunlight (avoiding skin cancer and other damage, while still getting enough vitamin D).
My current projects deal with three topics:
In the future, I would like to continue to find out what the optimum sunlight exposure for people is under various conditions. We have made a small start [e.g.,McKenzie, R.L., Liley, J.B. and Björn, L.O. (2009) UV radiation: Balancing risks and benefits. Photochemistry and Photobiology 85, 88–98 , and Norval, M., Björn, L.O. and de Gruijl, F.R. (2010) Is the action spectrum for the UV-induced production of previtamin D3 in human skin correct? Photochem. Photobiol. Sci. 9, 11-17 ], but we need more reliable information for a "recipe" that can be recommended to people.
I am a member of UNEP's "Environmental Effects of Ozone Depletion Panel" almost since its start after the Montreal Protocol. On this panel I have contributed particularly to the chapters on "Changes in biologically active ultraviolet radiation reaching the Earth's surface" and "Terrestrial Ecosystems", but also a little to other chapters such as "Health" (in the latter case regarding vitamin D synthesis). I am currently also a member of the EU supported consortium "UV4growth, COST-Action FA0906" (COST stands for European Cooperation in Science and Technology). Within this project I have organized a course in Szeged and coauthored "Handbook and good practice recommendations for research on the effects of ultraviolet radiation on plants".
Currently, my main hobby is insect photography. I like to tinker with home-built equipment, such as "The Amateur Scientist's Spectrophotometer" described in Chapter 25 of my book "Photobiology, The Science of Life and Light" (see publication list). I am now trying out a device for measuring infrared (thermal) emissivity.
I am half-time employed a professor at the South China Normal University. My activity there is described (in Chinese) and I am introduced (in English). One of my English-language lectures in China is reproduced at http://v.youku.com/v_show/id_XMjAzODYzMTg0.html
