Hi ;
I have the same visa officer, that is why we have the same order in getting medical and other issues. Officer asked us for updated documents(many forms in cic such as IMM...) and also bank statement, my situation ( certificate of enrollment at the university) and my husbands situation ( a letter from his employer) 2.5 months after our medical, we sent these things by regular post, then after like 1 month, again this officer asked for my husbands CV and list of publication, because he is doing a PhD (part time). and I am still waiting for PPR !
My suggestion for you is that, if you are a PhD student send them your list of publication and last CV and name of your previous and current supervisors right now.
