I am doing a PhD in the field of atmospheric chemistry at a good university in Canada. I feel I do not like my research very much and I am not very interested in teaching or doing research in my area.

But I will fulfill my PhD study and get a degree as an international student. In the meanwhile, I am learning or plan to learn a lot of online courses on coursera, especially in machine learning and data science.

I also think about quitting from PhD program and apply for a master/PhD in data science, CS, machine learning or something. But the investment would be huge and it may be not a good choice. I think maybe it is easier to get some courses online and certificates in a certain area like data science, and then I can convert to another area that I am more interested in in terms of future career building up. Also it is bad for my adviser if I quit from his group and I do not want to hurt anyone even if I am trying to seek for alternatives of my future.

My question is that is it easy to find a job in industry after I complete my PhD? Of course I will not find a job in my area but in data science.
