So I have the unique situation of having a former mentor that is to put it best MIA. He was the mentor for my MS and is no longer in the scientific research game not because of retirement or death, but because he got squeezed out of the game. And to make it worse, the dude fell off the grid, I mean his phone number has been changed, no longer answers emails, etc. Also no one in my former department even knows where he is, for all I know he could be living in a van down by the river. He was a good boss, but this is kind of a pain in the ass now when I need to include him as a reference in my CV, but he has no current academic affiliation or contact information.
Any suggestions? I'm installing LoJack on my Ph.D. advisor to make sure this doesn't happen again.
