Thank you all so much for your feedback, I really appreciate it. I will forget the the review! Ideally I would like to show the PI when I do apply, that I have continued to follow research in my field during these 'gap' years, but I guess I can't evidence that. And Dunham thanks - you have reassured me about publications, I guess I don't need to worry so much about publications at this stage in my career. I have the rest of my life to wack them out! ;)
