She is also developing new research on Canada's strategy for polar science and its place in Canada's national science policy. Additionally, Dr. Dey Nuttall is interested in exploring the leadership of Nordic countries in setting the scene for cooperation in the polar regions in the global context, in particular, their approach to promoting the notion of 'comprehensive security'. She is co-editor of International Relations and the Arctic: Understanding Policy and Governance (Cambria Press, 2014).

Wayne H. Pollard

Wayne H. Pollard is a Professor at McGill University. His research centers upon the field investigation of water and ice in cold polar desert environments of the high Arctic and Antarctic. Dr. Pollard’s long-term goals are to understand and explain the hydrological and physical processes that shape and define cold arid landscapes and to identify niche environments in permafrost that are capable of harboring microbial life at or near the limit of its habitability. His research ranges from the field observation and measurement of natural processes at the landform and landscape scales to the microscopic examination of soil pores, ice crystals and intra crystalline brine films.

Central to his research are:

• the investigation of the dynamic interaction between water and cryotic ground,
• the formation and degradation of surface and subsurface ice and
• the interpretation of the environmental significance of landforms related to permafrost, ground ice and ground water.

Dr. Pollard holds a Ph.D. from the University of Ottawa.

Peter Pulsifer

Peter Pulsifer is a research scientist with the National Snow and Ice Data Center (NSIDC), University of Colorado at Boulder. Dr. Pulsifer resides in Canada where he is a visiting research fellow at Inuit Qaujisarvingat: The Inuit Knowledge Centre. Before moving to NSIDC, he was a doctoral candidate and postdoctoral fellow working under Professor Fraser Taylor at the Geomatics and Cartographic Research Centre, Carleton University, Ottawa where he continues to act as a research associate. During his doctoral studies he was the lead researcher for an online atlas portraying, exploring and communicating the complexities of the Antarctic continent for education, research and policy purposes.

Since 2002, Dr. Pulsifer has been an active member of what is now the Scientific Committee on Antarctic Research’s Standing Committee on Antarctic Geographic Information where he has contributed to the conceptualization and development of the Antarctic Spatial Data Infrastructure. In 2003, he became the Canadian representative to what is now the Standing Committee on Antarctic Data Management.
