How do I combine Machine learning with nano-technology and fabbers?

I am into machine-learning already and I want to get into fabbers and self-replicating machines and nano-technology.

Is there any field that combines them all? Like could I use machine learning to figure stuff out in nano-tech?

I'm having a year off but will start uni next autumn and I have a hard time figuring out exactly what to study.

Main interest in machine learning is computer vision but really everything is interesting.
