From January, 2006 to October, 2011, and from May, 2013 to August, 2015 I was a part-time research assistant to Michael Slawinski in The Department of Earth Sciences at Memorial University of Newfoundland. My duties included proofreading of mathematical geophysics documents and assisting a Ph.D. student, Cagri Diner. This position (other than helping Cagri) resumed in early 2019 and the contract will end in early 2023 unless it is extended.
Here are some links related to my 2002--2004 and 2015--2018 Ph.D. residency at the university and that part-time employment:
