I am looking for a postdoctoral fellow to work on an NSF-funded study of the pattern and process of changes in tree abundance and treeline position throughout the Brooks Range of northern Alaska. The study aims to take advantage of approximately 25 different access points spread evenly across the ~600 mile range. The ideal candidate will have a background in tree physiology, forest ecology, soil biogeochemistry and/or dendrochronology and will have extensive experience traveling in remote wilderness areas. The fieldwork, which will begin in late May of 2019, will be physically and logistically demanding. Applicants should be willing and able to spend the better part of the summer field season (late May-early September) in the field and away from home. The position will be based in Anchorage during the remainder of the year. Laboratory and office space is available and affordable housing can be found within a bike ride of campus. Anchorage is a surprisingly diverse city with outstanding outdoor recreation opportunities, including more than 130 km of groomed Nordic ski trails within the city limits. To apply, please send a CV and cover letter to Dr. Paddy Sullivan (pfsulli...@alaska.edu).
