What Might I Study in a PhD in Biology Program?
Coursework in any PhD in Biology program sets up the formal basis upon which an effective dissertation project and thesis defense is built. To accomplish this, some universities divide their curriculum into different parts. This is a feature that could help students gain knowledge and skills tailored to specific interests, while still providing key information in a technical area. Most PhD Biology programs consist of the following.
- Biology program core courses
- Track-specific courses
- Electives that could be chosen in consultation with your advisor
- Research laboratory rotations
In biology core courses, students could study how to effectively teach at the college level or think critically in the life sciences. Because research is a big feature of a biology doctorate degree, you could also expect to see a course in quantitative analysis.
Electives are often chosen to reflect a students interests and may support a dissertation. Often, a biology department will include courses from other graduate programs to foster cross disciplinary inquiry. For instance, you might get to choose courses in applied mathematics, biomedical engineering, computer science, or integrative neuroscience. Electives vary by school so make sure to check out your options.
PhD in Biology Program Requirements
While PhD in Biology program requirements can vary between schools, there are some common features. First, candidates are expected to successfully complete all the core and elective credits taken within their program. In some universities, programs involve about 64 credits, although this is certainly a variable. Also, students typically must remain in what is called ‘good standing’. This usually means the school sets a bar of a 3.0 GPA or better for students to achieve in all their courses.
Comprehensive / Qualifying Exam: While specifics vary between PhD biology programs, once a candidate has finished their coursework, they usually take what is called a ‘comprehensive’ written exam. This tests the student’s grasp of course material.
Dissertation: From there, doctoral candidates may need to submit a proposal for independent study and their dissertation. The dissertation has its own requirements, which are generally outlined by a graduate school. Essentially, the goal is to represent a student’s original research or creative scholarship. The prospectus for the dissertation must also be completed and then approved by several bodies. These might include the readers, the director of graduate studies, and the department chair/program director.
Oral Exam: Candidates must then undergo a final oral examination. Here, they defend their dissertation as a valuable contribution to knowledge in their field and show a mastery of their field of inquiry.
Teaching Requirement: Some biology doctorate departments require students to teach while they are students. When this is the case, candidates might need to enroll in a first-year seminar course that provides guidance on pedagogy. Contact individual schools to learn if this might apply to you.
PhD Biology: Admission Requirements
Admission to a PhD in Biology program could require applicants to have a bachelors degree in biology or a related science. It might also be necessary to have a strong foundation in mathematics (calculus), chemistry (general and organic) and physics. But that’s not all. Some schools set a minimum grade point average of 3.0 or better, and GRE scores in at least the 50 percentiles. Letters of reference, and some indication that you have the potential to research are also required by some schools. Follow up with preferred programs for individual specifics.

Types of PhD Biology Programs
The type of PhD in Biology program you choose to undertake should reflect your goals and interests. In a general program, students might explore some of the broad sub-fields within biology. For instance, your program could cover cell and molecular biology, neurobiology, ecology, behavior, evolution, and marine biology. You may also seek programs with a narrow focus that might provide more courses in one topic. Biochemistry, Cell and Molecular Biology, and Genetics are several categories to consider.
- Biochemistry is the branch of science that studies the chemical and physicochemical processes that occur within living organisms.
- Cell and Molecular Biology is the study of biology at the molecular level and often overlaps with biochemistry and genetics.
- Genetics is the study of single genes and their role in how traits and conditions are transmitted between generations.
- Genomics is the study of all parts of an organism’s genes.
We have listed a few Phd in Biology programs you might explore below. Remember, each program may have unique courses, requirements and admission criteria. So reach out to a program adviosor to learn more.
PhD in Biochemistry and Molecular Biology
The PhD in Biochemistry and Molecular Biology program could provide you with an in-depth grasp of the life sciences at the molecular level. Future students could need one (undergraduate) year each of inorganic chemistry, organic chemistry, physical chemistry, physics, biology and mathematics courses.
Research programs in this area tend to weave the application of DNA technology into the study of gene regulation and protein structure – function relationships. As a result, you may get underway with laboratory research early on in your PhD program.
Opportunities for research usually depend on what the faculty projects are. You might figure out just what type of phenomena you want to explore, then match your goals with a great program and faculty. As a general example, research projects could touch on the topics listed below.
- Molecular biology of the cancer process
- Molecular neurobiology
- Genetics and biochemistry of bacterial and viral pathogens
PhD in Microbiology and Molecular Genetics
A PhD in Microbiology and Molecular Genetics (MMG) program might appeal to those who are highly motivated to pursue a career in biological or biomedical research. Typical applicants have a strong undergraduate background in the physical, biological or behavioral sciences. They might also have a desire to explore the basic principles of microbiology, biochemistry, molecular biology, and molecular genetics.
As you work towards a PhD in microbiology degree, your program is likely to explore microorganisms and microbial development. These courses are designed to prepare students to use microbial models to investigate basic problems in molecular genetics. In your research, you might choose from a wide array of topics. Antibiotic resistance, vaccine development, bacterial genetics and gene regulation are just a few examples. As you study these topics, you might also build skills in critical analysis.
