Biotechnology

The USA is the hub for MS and would be a much better option than studying in Ireland. It has a much broader base of colleges offering courses in MS, and degrees from the US are most definitely recognized across the globe. Some of the industries one can get involved with after completing M.Sc in biotechnology are as follows:
1) Research Institutes
2) Education
3) Hospitals
4) Power industries
5) Aviation Industry

Your rank in UPTU is good. I would recommend that you should participate in the counselling process and take admission in a good college.

You should pursue a course where your interests lie. Please refer to the link mentioned below for a detailed comparison between the two:
