Biology Major: Bachelor of Science Degree in Biology

Majoring in Biology is the perfect preparation for graduate school, medical school, veterinary school, or dental school. After grad school, many GMercyU biology alumni continue on to exciting research positions within an industry, a research hospital, or academia. That’s why research experience is a requirement for biology majors.

Your Bachelor of Science in Biology degree can also lead to direct entry into a well-paid, in-demand career in the sciences. Many GMercyU biology alumni have launched successful careers in the local area, a major pharmaceutical industry hub. 

Love science but unsure what career path to pursue? Our program will help you discover the right one for you. Or, choose one of the specific GMercyU biology career paths below.

Secondary Education Certification

Earn a biology degree with Teacher Certification

bachelors in biology

If you want to teach Biology in a secondary school setting, you can earn your Secondary Education Certification and/or Prek-12 special education certification through Gwynedd Mercy University’s School of Education. This option allows you to earn a bachelor of science in Biology combined with secondary teaching certification, a unique opportunity among biology colleges in PA.

*Certification: This program was designed to meet the certification requirements of the Commonwealth of Pennsylvania. If you reside in a different state, you should carefully review your home state’s certification requirements prior to enrolling in this program.

Associate Degree in Natural Science Degree Option

Earn a Two-Year Degree in Natural Science

 associates degree in biology

The Natural Science degree is a two-year program designed for students wishing to gain a foundation in scientific theory and practice. Students who earn their Associate of Science Degree will qualify for entry-level employment or continued education toward the baccalaureate degree. The degree is ideal for part-time students already working in the science field who are looking to advance in their current position. The program is closely aligned with the first two years of the Bachelor of Science Degree in Biology, making the transition from the AS to BS degree seamless.

Why Choose GMercyU

In addition to the unique program career paths above, GMercyU offers biology majors a compelling mix of educational advantages you won’t find at other colleges that offer biology:

  • Small classes with GMercyU’s low 10:1 student-to-faculty ratio
  • State-of-the-art laboratory facilities
  • Opportunities to conduct research and to present and publish your work, under the mentorship of experienced faculty 
  • Internship opportunities at companies like Johnson & Johnson and Novartis or research hospitals, such as the Children’s Hospital of Philadelphia (CHOP)

You’ll learn directly from experienced, full-time faculty members with doctoral degrees, as opposed to the teaching assistants (TAs) you may find at other schools that offer biology. This means richer learning opportunities in the classroom, the laboratory, and the field, as well as closer mentoring relationships with our faculty.


For more than a decade, GMercyU's biology degree graduates have scored at or above the national average on the ETS Major Field Test® in Biology. In 2020, GMercyU students ranked in the top 4% for molecular biology and genetics, the top 9% for organismal biology – animals, the top 12% for analytical skills, and top 16% overall among all other institutions whose seniors took the test.  

The Griffin Edge will help you connect the dots between your GMercyU experiences and your future aspirations, so you can ace future job interviews and launch a successful career. Learn more about the Griffin Edge below.

Research Experience and Labs

All biology majors are required to complete a research experience to prepare you for graduate school, medical school, or the workforce. And, almost every required course has a laboratory component, because the best way to learn is with hands-on experience guided by faculty experts.

See a lab activity completed by our Developmental Biology students — they studied the process of fertilization by collecting gametes from live sea urchins and mixing the sperm and egg together. 

GMercyU’s laboratories feature modern instrumentation and facilities for biology and chemistry: thermal cyclers, electrophoresis equipment, a research room with tissue culture hoods used for work in cell culture, and more.

Recent research projects include:

  • Studying how the brain’s neuroimmune cells contribute to alcohol-induced brain dysfunction and degeneration
  • Contributing to a national research project focusing on the search for new antibiotics secreted by soil-dwelling bacteria
  • Investigating organic compounds with the potential to function as anti-cancer agents

Students can also present their research, contribute to publications, and even receive a financial stipend for summer research. See what our Biology majors presented at our Spring 2020 University Research Conference!

Summer Research: See how students spent a summer sampling fish from a local stream and evaluating a variety of factors regarding responses to the environment and the reaction of the immune system to pollution. They worked side-by-side with faculty.

All of these research opportunities give GMercyU biology students an edge in their job searches and graduate school applications.

Additional topics include pedigree analysis, mutation and cancer, the conflict between nature and nurture, modern DNA technology, population genetics, evolution, and the ethical impact of genetics on society. 

BIO 402 Molecular Biology of the Cell
This is a project-driven laboratory course that introduces students to the world of mammalian cell culture. In addition to learning basic cell culture techniques, students will use cell viability assays, spectrophotometry, RNA isolation, reverse transcription PCR, and DNA gel electrophoresis to investigate important research questions in cell biology. Students will also gain experience in experimental design, data analysis, presentation of experimental results, and maintenance of a detailed laboratory notebook. 

BIO 415 Developmental Biology

Real-World Experience

The Griffin Edge

The Griffin Edge is comprised of five touchpoints -- Excellence, Engagement, Experience, Empathy, and Encouragement -- that become the cornerstones of your Distinctive Mercy Experience as a full-time undergraduate student.

The Griffin Edge includes an e-portfolio for documenting your GMercyU educational and extra-curricular experiences (no matter your major), reflecting on those experiences, and receiving feedback from faculty. It's designed to help you take ownership of your educational journey and chart the right career path for you. It will also help you learn how to talk about your college experiences in meaningful ways — and that can make all the difference in a job interview. 

For example, a student might say in a job interview: "I conducted research at the undergraduate level." 

A Griffin Edge student might say: "The opportunity to conduct my own research alongside expert faculty taught me the importance of being exact in my data collection and analysis. I was even able to present my findings at our annual research conference! I know this is the career for me."

Learn more about the Griffin Edge here.
