Extrapolating for the new post-doc position

Posted September 29, 2017 By grigoris

The idea of this post came to me on my second or third day in Chile when I noticed its flag on some boats. As today is my last day at work, perhaps it is the best (and last) opportunity to make a post about it. (So, practically it is either now or never.) My […]
