Marge Coahran holds a Master of Science from the University of Toronto in Computer Science (2005), and a Bachelor of Science from the University of Massachusetts in Physics (1987).  Her Masters project was in computer graphics, in which she developed a sketch-based system for designing Bargello quilt patterns. She subsequently spent seven years teaching computer science to undergraduates at the University of Toronto, Grinnell College in Iowa and Dickinson College in Pennsylvania.

Marge joined IATSL in August 2013 as a Research Associate. She currently is contributing to the following projects doing software development, hardware trouble-shooting, or whatever is needed at the moment:

She loves working with the IATSL team because of the variety of learning opportunities it presents, its interdisciplinary nature, and its focus on improving people's lives.
