I did my master degree by research in biomolecular sciences. And I want do phd I looking for scholarship, but its very hard. Is it possible to find a job and do the Phd in the same time.

It is possible to get a job as a research assistant and register for a part time PhD. Such possitions are highly sought after, as they are often better paid than a grant and their are less restrictions on the qualifications and nationality of the applicant. If you wish to work in an unrelated job and study for a PhD you may find that it becomes wery dificult to schedule experiments or to have time for anything else.

I want to do Ph.D in Agronomy UK and also work while studying
