Hi, I'm starting a PhD. Can I please get advice on how to choose where to go? Afterall it'll be a big committment for the next many years. I heard supervisors are important, but how will we know if we haven't worked with them, how can we find out? how much time are they supposed to spend with you? What about the institution, is it better to go to a large prestigious one or not? What would you advise in choosing the right PhD ? (health science biomedical field) thank you :)
