Allan is an algal taxonomist and author, interested in the changes in algal flora in response to climate and stress. He currently works on the chemistry of phosphorous in lake sediments, as well as analysing the growth of freshwater algae Nostoc at a Cumbrian site, and the mechanics of filamentous cyanobacteria. Allan holds an emeritus position at King’s College London and although his wife thinks him an extreme example of an academic, they do find time for other activities. They are regular fell walkers, favouring ravine exploration. They also indulge a little in the arts, as both like the music of the Baroque period and have a copy of an early harpsichord which is played on a regular basis. Scarlatti and the Bachs are favourite composers.
