I am a PhD student and my masters advisor is not replying to my emails. Why is he not replying?
When I was in the masters program he and I published a paper on a big journal. I am the first author. This has been cited ~100 times now.
About a year ago another researcher published a commentary article about our paper on the same journal. Since then I worked on a reply, and sent the full draft to my former advisor (coauthor of the original article) asking for review.
He has not replied so far, even though I reached out to him multiple times. As a last resort I informed him if you don’t reply by this deadline I will just submit this on my own. The deadline is approaching soon.
I don’t think I will get a reply. My question is, why would he do this?
