 If you think about working with us and want to apply, I highly recommend reading through [this link](http://www.thememolab.org/pages/gradapps/) prior to writing your statement. It is from the MemoLab (US-based), but many things apply as well. At some point I hope to write my own document, but this has to suffice for now.
