	Name/Email/Affiliation	Brief note
	Jerry Brown (edit) (jerrybrownigc.org) International Permafrost Association	Jerry Brown is the former president of the International Permafrost Association and the author of the Circumpolar map of permafrost and ground ice conditions. He has been active in permafrost research since the 1960s and is the author of many publications in the field of permafrost and has led the global initiative to produce the most up-to-date map on permafrost, which is probably the most cited scientific work in permafrost and periglacial research.
	Vladimir Romanovsky (edit) (ffveruaf.edu) University of Alaska Fairbanks	Vladimir Romanovsky is a world expert in research in the field of permafrost geophysics, with particular emphasis on the ground thermal regime, active layer and permafrost processes, and the relationships between permafrost, hydrology, biota and climate. His most recent research interests include the scientific and practical aspects of environmental and engineering problems involving snow, ice and permafrost. These interests include problems in the areas of soil physics, thermodynamics, heat and mass flow, and growth and decay processes that are associated with ice, permafrost, subsea permafrost, seasonally frozen ground and seasonal snow cover. He is currently working on the improvement of mathematical methods (analytical and numerical modeling) in the fields of geology and geophysics. His works have been widely cited by the International Panel on Climate Change reports.
	Charles Harris (edit) (harrisccardiff.ac.uk) Cardiff University	Charles Harris is a former vice-president of the International Permafrost Association and an emeritus professor of geology at Cardiff University. His main research interests are permafrost response to climate change, particularly in relation to slope stability. Charles Harris initiated a programme of laboratory and full-scale physical modelling has been supported by reduced scale modeling under elevated gravity. He conducted detailed real-time field measurements of periglacial slope processes (solifluction) in Dovrefjell, Norway and Endalen, Svalbard (permafrost) in order to provide calibration data for numerical models. Charles Harris co-ordinated the EU 4th Framework research project "Permafrost and Climate in Europe", acronym PACE (1997-2001, and subsequently, the ESF Scientific Network, PACE21, from 2003 to 2006. He also initiated projects pertaining to environmental monitoring, specifically of methane ground emissions.
	Hans-Wolfgang Hubberten (edit) (Hans-Wolfgang.Hubbertenawi.de) Alfred Wegener Institute for Polar and Marine Research	Hans-Wolfgang Hubberten is the current president of the International Permafrost Association and a renowned world expert on terrestrial and subsea permafrost. His interests lie in the reaction of permafrost to climate change and the links between the presence of subsea permafrost and methane. He has published ground-breaking manuscripts on the quaternary history of the Eurasian Arctic and redefined the history of permafrost genesis in these areas in partnership with Russian scientists. He has also published several papers related to the growth and degradation of permafrost on Arctic oceanic shelves and its impact on the storage and release of methane hydrates at depth.
