- Drug Discovery - These scientists employ expertise in molecular biology, cell biology, pharmacology, and today's hot biotechnologies like gene therapy or antigens to discover new drug molecules.
- Bio-informatics - As biotechnology or, precisely, genetics is mapping human genes, animals and plants, enormous amount of information is being generated. This information is about the nature and structure of the billions of genes that are being mapped. Bio-informatics specialists are combining knowledge of Structural Biology, Computational Chemistry, Mathematics and Information Technology to manage the huge information databases.
- Bioprocess Engineering - Various products like alcohol, processed foods, vegetables, meat products, enzymes required in pharmaceutical formulations, etc. are manufactured by biological processes. There are scientists working in this area of bio-processing to solve manufacturing problems, developing new processes, and so on.
- Genetics - in these field scientists conduct research into the biochemical and physiological aspects of heredity, specialising in the examination of DNA.They often concentrate on human genetics, which involves studying the biological basis for human variation and the causes of human genetic conditions. They are also directly involved in patient care, including prenatal diagnosis for genetic diseases and genetic counselling.

- Receptor Biology - Scientists here employ knowledge of multiple disciplines like Biology, Biochemistry, Biophysics, Bio-engineering, Molecular Biology, etc to research various exciting fields like protein engineering, drug delivery systems, etc.
- Cell Biology - Cell Biologistcarry on research in various new fields like Cell Therapy and Tissue Engineering. Cells are the engines and brains of many processes and the biologist who understands these new frontiers is a Cell Biologist.
- Biochemistry - Biochemists study the chemical make-up of living matter, as well as the molecular basis for the processes that occur in cells. They develop medical, agricultural, food science, pharmacological, industrial, environmental and other practical applications using their scientific expertise.
- Microbiology - Microbiologists study the growth and characteristics of micro organisms, such as viruses, bacteria, fungi, moulds and parasites, as well as their interactions with the environment. They develop industrial, medical and other practical applications.
- Sales and Marketing - Marketing and sales of bio processed products need special skills. Not only marketing skills, but skills in understanding and interpreting biotechnology are also needed. There are many biotechnologists who are actually working in sales and marketing
