Aim and objectives

The aim of this work is sometimes to make certain experiments possible. In other cases it has to do with making some methods and protocols more easily accessible to other researchers. Occasionally it has been driven by the need to use cheaper equipment.


Software: I have been developing software since the end of the 1970’s. I have developed statistical software, simulation models, a library for simulation modelling, software for controlling experiments (e.g. a modulated UV supplementation system). I have also developed software for controlling a proprietary gas-exchange system, and I am developing software for control and data acquisition with a spectrometer. I have have programmed in more than 10 different computer languages.

Hardware: I have designed and built and electronic auxanometer, digital thermometers, three-state temperature controllers and power electronics for controlled environments. Modified a gas-exchange system.


Sotware: I am currently writing software for diverse calculations related to photobiology and and quantification of radiation. There is a separate web site for this software at

Hardware: Special LED light sources for our experiments. Micro-controller based logger for UV and VIS radiation, and temperature. There is a separate blog with information on these work at

Information and disemination: Through participation in COST Action FA0906, mainly in the work group on UV technology, we have co-organized training schools and and co-edited a handbook of methods. See for more details.
