Biotechnology Engineering

Nishant sir, don't go with which stream is better. Go with what you want do after studying B.Tech. You may take following considerations. If you like computer, want to build crazy application or something related to software go with Computer Science engineering. If you like playing with machines/motors or electricity go ahead with Mechanical engineering. Or Electrical engineering. If you are India, after studying Electronics and communication engineering most of the students gets job/work in IT companies. Only few percent gets chance in electronics companies. So I would suggest, better to study Computer Science engineering. If you want to sail through vast sea go with Marine engineering. If you have not decided what you want to do after B.Tech, sit for one or two days and decided what you want to do. If still confused, select any of the engineering mentioned in point # 1, 2 and 3 (Computer Science, Electrical, Mechanical, or Electronics). Best of luck.

Future of biotechnology:
How many of your family members exactly know about Biotechnology? Forget family members how many friends know about this field? Now I think you got the answer, this field is still unknown in our country. So we are discussing about the future of the field which even after more than 20 years in India have not been implemented at that level that it'll reach the common man. Although if you'll discuss about the outcomes like jobs in this field:
R & D of Life sciences companies and Pharma companies do need people of this field but some of biotech jobs still taken up by chemical engineers and B.Pharma people. Patent searching companies do need B.Tech/ M.Tech/Graduates/ Postgraduates in biotechnology for their life sciences teams. Academics which is the major sector for jobs in this field or any other field (Like JRFs, PhDs and scientists).
State councils of Science and Technology do have researcher positions. Environment organisations do have positions for government funded projects. Some of major private research companies also have jobs for biotech people.

As with all statistics, salary numbers can be deceiving. There are two reasons why the numbers below should be taken into context. First, biotechnology careers typically require a Bachelor's degree for entry, but the field is filled with people who also hold Masters and doctoral degrees.For instance, 45 percent of the biomedical engineers who responded to an O*NET survey said a Bachelor's degree was sufficient; thirty-five percent needed a Master's degree and a further 20 percent needed a doctorate. Those with advanced degrees typically have higher earning potential, which partially explains how some biomedical engineers can earn around $50,000 per year while others are clearing $140,000.
Second, there are multiple employers of the scientists listed below. Some of the most prominent are universities, which typically pay less than companies engaged in applied research. Companies make profits, which can be shared with employees; universities do not.
