Mr. Burns - A Post Electric Play

Costume Designer for 3P's production of Mr. Burns - A Post Electric Play at Tufts Univeristy in Sprint 2019. In three acts, the show explores how culture changes and stays the same after an apocolpse through the lens of telling Simpson stories. 

Some Common Fate

In Spring 2020, Mandy Rosengren developed wearable technology for select costumes in Some Common Fate. Shown below are the different costumes designed to include sensors, motors, and LEDs.  Also featured are some of the costumes developed for this undergraduate research project in the Mechanical Engineering Department at Tufts University as well as for the play development. Due to the pandemic, the show could not be in full production, but you can see the sketches and some of the completed costumes by clicking the learn more button.
