PhD in Biology- Admission Process, Requirements, Fees, Duration, Job opportunities, Salary and Universities

PhD in biology or biological science is designed to provide advanced knowledge in the field of biology and related interdisciplinary subjects like ecology, genetics, microbiology, cell biology and molecular biology, etc to students through research. 

Biology is a subject to study life, including the study of animals, plants, microorganisms, cells and related things. It is one of the most popular subjects among students due to vast research opportunities. 

 Molecular biology, cell biology, genetic and microbiology like subjects are now very much in demand. Universities offer different types of doctorate courses in pure and applied biological science subjects. 

Based on the interest of students, they can choose their own study field and can do excellent research. A candidate with a PhD in biology can earn higher than a doctorate in another field. 

In the present article, We will explain to you the entire process of getting a PhD degree in any subject of biology.

Admission process: 

To be eligible for doing a PhD in biology or biological science one should have a master’s degree or post-graduate degree in biology, biological science or related interdisciplinary subjects. 

Minimum of 55% mark of 5.3 GPA (in USA) in the overall masters degree is compulsory to apply for the same. 

M Phil after the master’s degree is also taken into account for admission procedure. Some universities allow the M Phil student to directly appear in the interview without the entrance exam. 

However, for other students, after completion of master degree, the entrance exam is compulsory, it is conducted by either university itself or by the central body. 

Note that some universities in the USA and UK directly allow students in the PhD interview without taking an external examination. Their research background is preliminarily considered during the interview. 

A good score in IELTS, TOEFL and GRE is required for foreign students.

Process of admission: 

Usually the process of PhD admission is streamlined by universities. 

First, apply online through the official website of the university following the notification.

Upload all the documents (enlisted elsewhere in this document) while filling the form. Download the hall ticket. 

Appear in the entrance exam on the given date with the hall ticket if applicable. 

After clearing the entrance exam, you have to appear in the personal interview during which the candidate has to verify all their original documents and submit the research proposal. 

A research proposal must include the problem, method to evaluate the problem, general introduction and other related information in a 10 to 12 pages. 

In the next stage of admission students have to select their research guide or supervisor under whose supervision they have to complete their PhD. 

After completing all these steps, at the end of the first year, a candidate has to clear the course work examination, compulsorily in order to continue PhD. 

Steps in admission: 

  • Follow the notification 
  • Apply online 
  • Upload all documents
  • Download hall ticket or form. 
  • Appear in the entrance exam if applicable
  • Choosing the PhD guide 
  • Appearing in the PhD interview 
  • Document verification
  • Clearing the course 

Documents required: 

  • Undergraduate and postgraduate degree certificate and marksheets
  • Living certificate 
  • Result of clearing entrance examples like NET, GATE, JAM or JEST. 
  • University transcription 
  • IELTS, TOEFL or GRE marksheet if needed. 
  • Research proposal 
  • Recommendation letter from the guide 
  • Student consent letter 
  • Other related documents

PhD in biology: duration 

Usually as per the university rules and regulation, a candidate has to pass a minimum of 3 years during their PhD tenure to complete the research. Although it may take longer. 

PhD in biology takes 4 to 7 years to complete the research. For some extensive finding it may take up to 10 years, there is no time bound for that. However, a student has to justify their progress every semester. 

PhD in biology or related subjects takes more time to complete in comparison with other subjects. The reason is extensive lab work. A candidate has to do lab work, perform trial and error experiments, check protocols and SOPs to even start their work. 

Also he or she has to do wet lab work as well as dry lab work too. Doing a PhD in biology or biological science it’s tedious process and takes more time.
