Post PHD carrer life
What is the usual path of post Ph.D. in these fields?


There are two main options:


Pursue in academia as a postdoc, usually in the hope of eventually reaching a tenured academic position.
Apply for industry positions, either for research-oriented jobs (often found in big companies R&amp;D departments or innovative start-ups) or non-research jobs for which PhD skills are required or recommended.


So if by "continue learning" OP means "keep doing research", there are options outside academia. Personally I often encourage PhD students who are close to graduating and haven't made their mind up to consider applying for a postdoc: it's a short contract which gives you a taste of the academic career path while also giving you a job experience, thus leaving all the doors open.

This question might help clarify the landscape of post-PhD options.
