For students who have a natural inclination to pursue studies in the sciences, and specifically the field of biology, an obvious question should be considered at the start of that educational journey: what can you do with a bachelor’s in biology?
On the surface, the answer to that question may seem more straightforward than it actually is. When most people envision a biologist or someone working in the field of biology, more often than not, they see a person in a white lab coat peering into a microscope in a room filled with beakers and glass slides.
They’re not wrong. Spending time in laboratories conducting research and using a microscope to closely examine various specimens is a very real outcome for many professional fields that are directly linked to the study of biology. But if you dig a little deeper, you may be surprised at just how many different career paths a bachelor’s in biology could take you.
This misunderstanding of what’s possible as a future career for students interested in the field of biology is something that biology professors have become used to dealing with.
“There are a lot of paths that someone with a biology degree can take, I do think many times people don’t realize just how broad the options can be,” says Dr. Michael R. Maxwell, professor in the Department of Mathematics and Natural Sciences at National University. “There are more traditional fields like medicine and health care; things like plant biology and conservation biology, which is very big here in San Diego; and newer areas like genomics and bioinformatics in which there are going to be a lot of opportunities moving forward.”
To better understand all the possibilities that can open up by earning a bachelor of science in biology, it’s best to start by ensuring that you have a comprehensive understanding of the field itself — what it’s about, the purposes it serves, and its position within the broader realm of science.

We spend our lives surrounded by living organisms, from those that are so microscopic in size and scale that they can’t be seen by the natural eye to others that are so massive that they can be hard to even comprehend.
The field of biology is the study of those living organisms, including things like their physical structure, physiological mechanisms, chemical and molecular interactions, and even how they came to exist in the first place and how they’ve evolved over time.
In terms of what biology is, that’s the short answer. But as you might expect, there’s much more involved when it comes to truly understanding the field. As one of the “hard sciences,” biology can be broken down and examined in a much more intricate and comprehensive manner. For instance, it’s widely agreed that there are seven main branches of biology, and within many of those main areas is an even greater number of subfields or subdisciplines in which biologists, and those pursuing a bachelor’s in biology, can focus their concentration. These main branches of biology include:
- Botany – Botany is the study of plant life in an effort to classify, describe, and discover more about their reproductive methods, physiology, and morphology.

Clearly, there’s a lot to understand about the field of biology for the purposes of determining whether a bachelor’s in biology, or any other bachelor’s degree in science, is right for you. But that’s only half the equation. It’s just as important to take a close look at your personality, interests, and natural characteristics as a way of determining if you’re a good fit for the field.
It would be misleading to suggest that in order to succeed in the field of biology, a person must have a defined set of personal characteristics or traits. That’s simply not the case. Every person out there working in the field or pursuing a bachelor’s in biology is an individual with unique strengths, talents, backgrounds, and professional goals.
That being said, there are personal skills and characteristics that do contribute to a person being drawn to biology and thriving in any of the professions to which a degree can ultimately lead. For instance, while you’ll find many biologists who work primarily in outdoor settings and personally enjoy being out in the field, you’ll find others who aren’t interested in the outdoors and instead prefer spending the majority of their time in an indoor lab setting. At NU, Dr. Maxwell estimates around a 50/50 split among undergraduate biology majors who prefer working outdoors to those who would rather spend time inside the lab.
Still, it helps to be aware of at least some of the broader characteristics and areas of interest that can contribute to a person’s ability to succeed in biology. Some of these include:
- An Interest in Science
For anyone thinking about a future as a biologist or a related field, it would obviously help to have a real interest in the basics of science. If you enjoy equations and reading about science, are always curious about the “why” of things, and like keeping detailed information about the results of projects and processes, those are good signs.
- A Love of Nature
Several areas in the study of biology involve an exploration of living organisms in the natural environment, so if you enjoy spending time in outdoor settings like forests, rivers, coastlines, and other ecological habitats, you may be a good fit for many of those branches of biology.
- A Love of Laboratories
As Dr. Maxwell indicates, many people who don’t necessarily enjoy the outdoors still thrive as biologists when they bring a genuine interest in conducting laboratory work. And even those who do work in outdoor environments will still dedicate some of their time working in indoor lab settings.
- A Passion for Solving Problems
The study of biology is a solutions-oriented endeavor. Whether the work is related to medicine, the environment, animal health, climate change, or countless other areas, it’s essential that those in the field are dedicated problem solvers.
- An Attention to Detail and Organization
If you’ve ever done research or any kind of laboratory work, you know how important it is to be very detail-oriented and organized in your work.
- An Active, Hands-On Learner
As a student in a biology bachelor’s program, much of your learning experience will take place in an active, hands-on setting. There will definitely be classroom learning as well, but if you enjoy rolling up your sleeves and learning with your hands, biology could be a good fit.
What Can You Do With a Bachelor’s in Biology?
A bachelor of science in biology opens up a broad array of potential career paths. Among the first things to consider for anyone studying biology is whether they want to use the undergraduate degree to enter a professional field directly, or as a foundation for advanced study leading to a graduate degree.
“One of the more common ways students utilize the degree is by using it as a foundation for an advanced professional degree in a health care field like medicine, dentistry, and veterinary medicine,” Dr. Maxwell says. “If you’ve ever been sick or had a pet that’s needed medical attention, which everybody has, then the odds are good that the person they’re seeing has a biology degree.”
Graduate programs in other, non-healthcare disciplines are another popular option. Some of these master’s and doctoral degree options include areas like plant biology and agronomy; entomology, which is the study of insects; conservation biology, which can lead to positions working in animal parks and habitat facilities; and genomics, also referred to as bioinformatics, which is the study of the genetic sequencing used in everything from DNA research, to ancestry research, to animal breeding, to crime scene investigations.
“Genomics and bioinformatics will continue to see a lot of growth, I think, it has become popular with all of the interest in things like ancestry.com, as well as investigations using DNA research,” Dr. Maxwell says. “That’s an area we’d like to build up more at NU. There’s a lot of genetic sequencing data being generated, we’re going to need people who can manage it.”
For those looking to enter the professional world after earning their bachelor’s in biology, there’s an equally impressive range of possibilities. Some examples include:

“One of the big areas of opportunities here in San Diego is in conservation biology,” Dr. Maxwell says. “We have all these world-class zoos and animal parks, they need well-educated and well-trained conservation biologists. And they do really amazing work. One of the reasons it’s known as the “World Famous” San Diego Zoo is because they’ve stopped species from going extinct through their work, and they’re continuing to do so as we speak. So the opportunities are huge.”
