Nearly 300 postdoctoral researchers and graduate students attended masterclasses on the visual communication of materials science and engineering between October 2013 and January 2014. At programs offered in partnership with the Departments of Mechanical Engineering, Chemical Engineering, and Materials Science and Engineering, Felice Frankel, research specialist at the MIT MRSEC, presented 90-minute talks addressing common errors students and faculty make in the graphics and images used in their presentations and publications. Her book, Visual Strategies, a Practical Guide in Graphics for Scientists and Engineering was the foundation of companion workshops that engaged smaller working groups in directed discussion and critique of images submitted by participants.
