Biography

Associate Professor
Department of Mathematical Sciences
Trinity Western University
August 2012 - ongoing 

Adjunct Professor
Simon Fraser University
November 2012 - ongoing

He has held post-doctoral research positions at the University of British Columbia (UBC), Simon Fraser University (SFU) and Aberystwyth University and has been a sessional lecturer at Simon Fraser University (SFU) and University of the Fraser Valley (UFV).

Research & Scholarship

Dr. Sam Pimentel’s research program has made important contributions in glaciology, oceanography, and data assimilation. He uses and develops mathematical and computational methods for simulating ice sheets, glaciers, and ocean temperatures.

Education

Ph.D., 2007, University of Reading, UK
