Phusiopoiesis?

Debbie, we had a great time talking about your book in seminar this morning. One question I dared not answer, though I did manage to pronounce it outloud, was about "phusiopoiesis"--one student said she googled it to learn more and only found your name again. Another asked if it was merely metis & kairos combined. Could you perhaps share some more insight into this term and its usefulness for your work?
