To obtain a PhD in biology, students must meet prerequisites, research programs, and complete four to seven years of work, including core courses, electives, and a dissertation. Admission requirements vary, but most schools require a bachelor’s degree in a life science field, high scores on standardized exams, letters of recommendation, and a personal statement. Some schools prefer students with a master’s degree, and some have comprehensive exams. Online PhDs may not be equivalent to a university degree.
Obtaining a PhD in biology is a matter of meeting the prerequisites for acceptance into a college and then working four to seven years to complete all assigned work. There are numerous biology programs, and students should consider each program’s focus to determine whether it matches their interests. It can take some work for students to thoroughly research available doctoral programs.
The minimum entry requirements for schools that offer a doctorate in biology are that students have a bachelor’s degree, which may or may not be in biology. It may be in a closely related field and, in almost all cases, should have a life science focus. Some schools only admit students with a degree in biology, and some colleges are more demanding. They may prefer students with a master’s degree or will not accept students for a doctoral program until they have completed all master’s requirements. This means that the student starts as a master’s candidate and only advances to the doctoral candidacy by successfully completing a master’s degree.
In addition to undergraduate or graduate prerequisites, many schools have other requirements for applicants. Many schools require high scores on standardized exams, such as the GRE and the Graduate Record Examination (GRE). It is true that schools want strong academic performance with a high grade point average, especially in science and math subjects. Students also need letters of recommendation and will need to write an excellent personal statement as part of their application.
Once a candidate is accepted into a doctoral program, he or she can expect to spend approximately four to seven years completing all the requirements for a doctorate in biology. If the entry took place at the master level, then this time can be slightly reduced. Each school may have different types of studies, but most have core courses and then many elective students can take. In addition to attending classes, students often work as research assistants or sometimes as teachers or section leaders.
Many schools have comprehensive exams that they require students to take before they are approved to begin work on a dissertation, which is an original piece of research. It can take several years to complete, and PhD candidates in biology often have access to laboratories to conduct experiments that will be discussed in the dissertation. Once the dissertation is prepared, students present it in public and must be reviewed by the faculty. Passing, in addition to meeting all other graduation requirements, means the student receives a doctorate in biology.
Changing elements in education mean that some students now obtain their PhDs online. For subjects like biology, where so much laboratory and hands-on research is needed, this may not be equivalent to a university degree. If students are interested in an online Ph.D., they should ensure that it is similar to the Ph.
