I'm a PhD student and a full-time researcher in my uni. This year I was assigned with supervising of one Bachelor's thesis. My PhD supervisor invented a topic, which is really interesting, but a really difficult one for this level (combination of quantum chemistry and neural networks).
Student, who assigned for that, has a programming background, so he doesn't have much experience in mathematics or a theoretical computer science. Nevertheless, I believed he can catch up and I had some literature prepared for him.
At first he didn't contact me for the first several weeks, which made me pretty nervous and I wrote him a polite reminding e-mail with a consultation suggestion. He came and we agreed on some plan. Several weeks later, on our second consultation he showed just a little real progress, but I still considered it ok, believing, that he's studying the underlying theory beforehand.
The problem is now, that he didn't show up since and I had to contact him again, only to find out, that he was too occupied by his job and that he will be writing e-mails with his progress.
So, I'm afraid, based on his behaviour, that he tries to appear independent and to develop the software for the thesis on his own. That could be a real problem as he will progress too slow without any guidance (he has NO previous experience with his topic, except programming skills).
So, my question is - how can I politely persuade him to communicate with me more often? I really want him to successfully finish his thesis, both because of my "score" during PhD and because I would otherwise feel guilty of ruining someone else's career.
