How to go about building up my profile for a Ph.D in Biological Sciences

[LumosNox]

I am going to start my third year of undergraduate studies. I'm pursuing a B.tech in Biotechnology, which is a four year course, from India. I am quite interested in pursuing higher studies in the field and am quite confused as to how should I build up my profile to increase my chances of getting into prestigious universities in the USA. I have already begun preparing for GRE and would surely be thankful for any advice on how to proceed further.

Hello! A good place to start might be going to the recent applicant profiles threads in the Life Sciences > Biology subforum. You may be able to get an idea of the kind of CVs that PhD applicants have who are applying in the same fields as you will be. 

I can also say right off the bat that besides meeting the GPA/GRE/TOEFL and class requirements, the most important part of a successful application is research experience. If you haven't already, seek out opportunities for research experience in relevant fields wherever you can.

Focus on getting research experience. If you can work in a lab and make significant contributions (research papers, conferences, etc)
