hi
i'm a medical doctor and need to continue in tissue engineering (regenerative medicine-PhD). may it possible to do this with a 10000$ fund??

1) What type of dollar?
2) Are you already part way through or would you be starting from the beginning?
3) Are you planning to be based in the UK?
4) Will you have to pay fees from this sum AND support yourself? International (non-EU) student fees for a full-time PhD can be £9000-£12000 GBP per year.

i'm just goinng to start with a 10000US $ of fund in Uk or US,may it be possible for me to get a research or any part-time job for my forthcoming expenditure?

If you are coming to the UK then as part of you visa application (if you need a visa), you will have to show that you have sufficient funds to complete your course WITHOUT working. Usually, once you have a visa, it will allow you to work up to 20 hours per week but remember that if you are spending this much time working, you are unlikely to be able to complete a fulltime PhD in a timely manner.

10,000 US$ would be almost 5000 UK£ which is only a quarter of what you will need PER YEAR.

You need to find a position that will give you funding, even if its only the university fees.

what's your suggestion? should i give it up?

No, don't give up but study funding possibilities, start with http://www.findaphd.com/students/funding.asp . You may also ask the department you plan to apply to.
I agree that 10,000$ would not be enough to finance a PhD, in my opinion it would only cover your living costs for 1 year (and you would have to be really careful about money and hardly buy anything), tuition fees excluded. As for the possibility of getting a job, consider two things:
-As an international student the number of hours you can work will be limited (I think 20 hours per week).
-Although many students manage to find a part-time job, maybe you will just have bad luck and won't find any. That can happen as well so don't rely on this possibility.
I think the better thing is to start a PhD having already a good idea on how you will fund it (already awarded scholarships, savings...) so that you will be able to finish it even if, during the 3 years, you don't get a part time job, extra funding...

thank you all :)
