Nils Mole works on problems in turbulent diffusion, in particular on the atmospheric dispersion of hazardous gas clouds. The specific topics of main interest are: the relationship between statistical moments of the containment concentration; mathematical modelling of the concentration moments; the probability distribution of concentration in meandering plumes; measurement errors in concentration data; application of statistical extreme value theory to large concentration values. He also does some work in collaboration with the solar physics group, on the effect of random flows on solar oscillations.
