This question already has an answer here:
I am a 3rd year phd student. I have a good human relation with my advisor, who generally leaves me a lot of freedom in deciding my work and my next steps.
However he recently started a personal business that is capturing all his time and interest. The consequences are:
- He started skipping the scheduled meeting, being available more or less once each three weeks.
- He rarely reads what I send him, and if he does, he does it in the minutes just before we meet.
In general I feel that he has lost any interest in my supervision, to which he dedicates just the time of our meetings. This in generally reduces the quality of what I produce and of the directions that my research can take.
At this point, I am considering the possibility of propose him to add a co-advisor to my PhD. In fact we are having a good collaboration with another professor from a different department (biology, I am in Cs) who seems very interested to my research; but I have no idea if he might be interested in co-advising me.
Might this be a good solution? And how to propose this to him without even hurt the good relation that we have?
