If you love to work in a laboratory, enjoy sharing what you know about biology and the wonders of the human body with others, or would like to be a respected researcher one day, a biology PhD might be just the right choice for you.

While it is a degree heavily focused on in-depth research, it is a great way of starting your scientific career, as many graduates are hired for postdoctoral research positions. Even though temporary, it gives them a chance to work with experienced scientists, learn their techniques, and broaden the knowledge they already have in the field they chose to pursue. Some go as far as publishing works containing all of their observations from that period of time.

Biology is such an extensive academic discipline that everyone is bound to find the area they would like to pursue their career in – including Molecular Biology, Computational Biology or Marine Biology.

PhD in Oral Biology

The oral biology PhD course, as the name suggests, is recommended for those who wish to continue their research in dental medicine. It focuses on the oral cavity – the structure, function, and development of tissues inside of it, as well as their interrelationships with other organs in the human body.

PhD graduates in oral biology usually work either at a university or at a hospital, where they can continue their research with clinical dentists’ help. Some choose to teach biology, microbiology, or pathology on the postsecondary level. With an additional teaching degree, they can teach biology in high school.

PhD in Cancer Biology

PhD in Cancer Biology provides the students with all the necessary knowledge and research training to contribute to the progress in research about the prevention, detection, and treatment of cancer. In most cases, the program’s curriculum will include subjects like disease pathology, basic cell biology, and translational research.

With a PhD in cancer biology, you can decide to either continue your academic career and research or combine it with a medical degree and devote yourself to treating patients. Some of the jobs you can take up include biological science professor, medical scientist, oncologist, oncology surgeon, or health specialist professor.

PhD in Molecular Biology

Molecular biology is a study of the structure and nature of the molecular building blocks of matter and life. A PhD in molecular biology focuses on the interaction between different cells in the body, including the natures of DNA, RNA, and more.
There are several careers that you can choose from with a doctorate in molecular biology in education, healthcare, or scientific institutions, including biochemist, biophysicist, medical scientist, microbiologist, natural science manager, or postsecondary biological science teacher.

PhD in Marine Biology

Marine biology is one of the fields of oceanography. The degree focuses on the physiology, biology, neurology, habits, and behaviors of marine organisms, and may include the study of their interaction with their ocean environment. Some of the topics students of marine biology will cover in class include marine conservation, marine evolution, chemical, physical and biological oceanography, applied marine biology, and more.

As a marine biology doctorate, you can decide to pursue a career as, for example, a biology professor, biology teacher, wildlife biologist, hydrologist, aquatic scientist, or environmental scientist.

PhD in Computational Biology

Computational biology involves using computers and computer science to understand and model the structures and processes of life. It uses computational methods, such as algorithms, to represent and simulate biological systems, as well as to interpret the experimental data.

With a PhD degree in computational biology, you have several career options available to you. Those include zoologist and wildlife biologist, biochemist, statistician, microbiologist, or natural science manager. What’s more, since the degree is not only focused on biology, but also on technology, you can take up jobs such as data analyst or data scientist.

PhD in Biology – Admission Requirements

The school might require you to have a bachelor’s degree in biology or a related field to get admitted as well as skills in mathematics, chemistry, and physics. For some graduate programs, you might need to have a minimum grade point average of 3.0, as well as letters of reference, or some other indication that show your potential to research.

Obtaining a Biology PhD – The Requirements

Even though the requirements will vary depending on the school and the area of study you choose to pursue, it is possible to distinguish some common features between all of them. First of all, all the students that are interested in obtaining a PhD need to successfully complete all the core and elective credits they took within their program. Secondly, the students need to remain in the so-called ‘good standing,’ which usually means that they need to have a GPA of 3.0 or higher in all their courses (although the required GPA might differ depending on the university).

Once a PhD candidate has finished all the coursework, they will most probably have to go under a qualifying exam, which is a test that shows how well the student has grasped the course material. However, keep in mind that this varies between PhD biology programs, so it is possible that you will not have to go through an exam.

When that is done, the candidates are faced with another stage of recruitment – they need to submit a proposal for independent study, as well as their dissertation (of which the graduate school usually outlines requirements. The doctoral candidates must also submit a completed prospectus for the dissertation, approved by several parts such as the director of graduate studies. Once they have it done, they go through an oral exam, during which they need to prove that their dissertation will be a valuable contribution to knowledge in their field.

Keep in mind that some graduate schools might require their students to teach while they are enrolled in the PhD program – they go through a seminar that introduces them to pedagogy. If you want to know if that’s the case for the graduate school you wish to attend, calling them is the easiest way to find out.

The Bottom Line

If you are still wondering whether a PhD in biology is the best option for you, here are some things that you should keep in mind. A PhD in biology will not only give you a better understanding of the world, and the microorganism inhabiting it, but it will also help you extend your knowledge when it comes to laboratory work. Graduate students are able to conduct proper research and catalog the data and information they have collected, which allows them to pursue a career outside of academia.

Because of the fact that biology is such an extensive academic discipline, there are several areas of study that you can put your focus on, depending on what interests you the most – so, not only you will be securing your future, but also doing research about something you are genuinely interested in.
