Hi guys

So I am applying for PhD and believe the Wellcome Trust one would be great for me. I like the fact you can try out few research groups and make an informed choice.
Is anybody doing this PhD?Do you have any tips for my cover letter/writing application? When they ask me about my career aspiration how much into future should I go? Is it enough to say I want to stay in academia or should I mention I want to eventually have my independent research group and supervise PhD students?
Do I keep it short and brief? How do I describe my research experience? Very brief?

If any of you (not explicitly WT students) could help I would be most grateful.
