Ruoff is a physical chemist at the University of Stavanger with interest in reaction kinetics of chemical and biological systems, as well as industry related research.
The research group works on chemical and biological oscillators; especially with the BZ reaction and circadian rhythms. The BZ reaction is a chemical oscillator that can show concentration oscillations, sometimes for hours, even in a simple beaker.
Apart from oscillatory behavior, chemical oscillators show a variety of surprising (and quite fascinating!) phenomena that normally are associated with biological systems; for example excitability, bistability, chemical pulse propagation and spontaneous structure or pattern formation. Even chaos can be observed.
Other fields of research are enzyme kinetics and the study of dynamics and properties as well as temperature compensation of circadian clocks. In these studies the fungus Neurospora crassa is used as a model organism. The Ruoff group also works on an systems biology approach how metabolic pathways adapt to changing environmental conditions.
Offshore and food
In industry-related projects the group has studied precipitation kinetics of gas hydrates, polymer crosslinking as well as applying NMR and fluorescence spectroscopy to various problems in offshore industry.
In cooperation with food research institutes we have been using PCR and RT-PCR techniques for rapid identification of toxic gene products from contaminating microorganisms in foods.
