Current Research

Currently studying genetic variation on a global scale in the bi-polar lichen Ochrolechia frigida with a view to determining the extent of genetic variation in Antarctic populations. principal Arctic interests are in the ecology of lichen-dominated ecosystems, particularly their nitrogen and phosphorus economies, including the role of lichens in nutrient capture from the atmosphere and nitrogen fixation. Most recent Arctic fieldwork was in northern Komi Republic/Nenets Autonomous region investigating impacts of acid deposition from local (Vorkuta, Inta, Usinsk) and long range sources.
