Undergraduate - POSITION OPEN

Position Description


The Water and Environmental Research Center (WERC) is seeking an undergraduate student to support hydrologic modeling and hydrologic and geochemical field measurements of a glacierized catchment underlain by discontinuous permafrost.

The undergraduate Research Assistant will work closely with two graduate students to assess what role glacier wastage play on lowland hydrology and permafrost in the Jarvis Creek and Tanana River basins, Interior Alaska. The position includes multiple field trips in summer to perform glacier, meteorological, hydrological and/or geochemical measurements, while fall and spring semesters mainly include data processing.


We seek motivated candidates who are working towards a B.S. degree in geosciences, physical geography, physics, chemistry, engineering, or related fields. Experience with field work, GIS and programming is desirable. Good oral and written communication skills are a prerequisite.

Application Process

The earliest anticipated start date is July 1, 2013. US citizen, US residents as well as international applicants studying at the University of Alaska Fairbanks Campus are welcomed. Students can work up to 20 hours per week during the academic year and 40 hours per week during the summer. The position is available for the duration of the project (July 1, 2013 – Sep 30, 2016).

To apply for the undergraduate research assistant position, please contact Anna Liljedahl (akliljedahl@alaska.edu). Please submit via email the following information, preferably in a single pdf: (1) a cover letter stating your motivation for the particular project, (2) a CV including contact information of three referees, and (3) transcripts of your academic record.
