Microbiology

Hello Mohan,
It's very nice to see that you have still hunger fir studying. It's great. Yes, the institute you ate seeking admission for PhD is good. You should finalise your guide and then research topic with his help to start your progretin getting PhD.

Microbiology is the essence of public health and medicine. As more and more organisms achieve better survival with our current medications, there will be a renewed emphasis to develop newer ones just to keep up. Again, a doctorate would be better.
Lastly, biochemistry is closely tied to the prior 2. The basis of much of the newer drugs isn't necessarily by chance. As we understand receptor sites, membrane science and actions of enzymes and amino acids, then there is a better chance at helping us extend life.

Banasthali Vidyapeeth is the top-most university in India for women. Placement records are very good for M.Sc and biotechnology.

Yes, obviously, but you could have chosen good technology or food processing technology as you have a very good background of microbiology and chemistry. This line provides you better scope but it's okay that you are doing Diploma in nutrition as this also has a bright career. Whatever you are doing, do it with all your focus and you will come out with bright colors.
Thank you.
