Research Interests

I have a particular interest in lichens of the family Verrucariaceae, which are found especially beside streams, on coastal rocks and on limestone. Many of the species are difficult to distinguish, and I use DNA sequencing to assist in classification and identification, and discovery of undescribed species. I also address other unresolved problems in other, mainly British lichens, with recent or ongoing studies on Aspicilia, Caloplaca, Trapelia and others. I have an interest in the lichens of the Falkland Islands.
