Science

Much depends on your research and publications. They are compulsory for a better career. Otherwise, you may have to wait for a long time to make a good launching.

You can opt for a combination of both: Medical biotechnology is the use of living cells and cell materials to research and produce pharmaceutical and diagnostic products that help treat and prevent human diseases. Most medical biotechnologists work in academic or industrial settings. In academic laboratories, these professionals conduct experiments as part of medical research studies; industrial biotechnologists work toward developing drugs or vaccines. The medical biotechnology field has helped bring to market microbial pesticides, insect-resistant crops, and environmental clean-up techniques.

Both these field has a very wide career, but it is totally depends on your interest. Just choose according to your choice. But there are vast employment opportunities
for the students of Biochemistry as they can be absorbed in a number of Research Institutions and the students of Biochemistry can work as Scientists, research
officers, research associates, chemical examiners.
