Today we met the amazing Michelle Mellenthin, a biomedical engineer and post-doctorate researcher. We learned about her experiences with Engineers without Borders and her current research on technology that helps damaged lungs function properly.

We then got to construct our very own Foldscopes (origami microscopes) and used them to look at images of healthy vs. damaged lung tissue, among other things! We were even able to attach the Foldscope to a cell phone camera for a more enlarged view.

The Foldscope was developed by Manu Prakash and designed to cost less than $1 to build. It is part of the "frugal science" movement which aims to make cheap and easy tools available for scientific use in the developing world.
