Biology

Department Description

The Department of Biology endeavors to acquaint students with current biological principles, to educate them in the scientific approach to problems, to provide experience in laboratory and field methods of investigation, and to develop an appreciation for intellectual achievements in science. In addition, the courses are designed to prepare students concentrating in biology for research jobs, graduate study, teaching, or a career in a variety of medical areas. A semester of study abroad is feasible and recommended for four-year biology majors.

Study Abroad

Saint Mary’s has a long history of providing quality international programs as an essential part of our educational mission—forming women leaders who will make a difference in the world. As this world becomes increasingly interdependent, the College offers an expanding range of semester, year, semester break, and summer study and service programs in a wide variety of countries, and encourages students to take advantage of them. Learn more about the various Study Abroad opportunities.

GRADUATE STUDY

By fulfilling the requirements for a Bachelor of Science degree in biology, the student also has sufficient course work in mathematics, chemistry, and liberal arts for admission to graduate school.

Medical School and health professional programs

The Biology Department's coursework supports the preparation of pre-health students, including for the health professional exams such as the MCAT, DAT, OAT, and PACAT. Coursework provides the knowledge and skills to be successful in these graduate programs and in the medical field. (See Pre-Health Professions Page for more information). 

Teacher Preparation

The Department of Biology, in conjunction with the Education Department, offers courses leading to state licensing for teaching sciences in secondary schools. This preparation includes successful completion of the degree in biology.

BIO 375  Problem Solving and Preparation for MCAT, DAT, OAT, PA-CAT  (2)  

The focus of this course is to take skills learned across the curriculum in the Arts and Sciences at Saint Mary’s and integrate these skills to develop a deeper understanding of biological principles. Having the ability to integrate and analyze information from different disciplines in the arts and sciences is critical for success in graduate school, professional school, and beyond in the sciences and in healthcare. This course focuses on these natural phenomena and applying these skills to understand and analyze biological principles, common skills that are necessary for success on professional programs entrance exams. This course is heavily geared towards students taking entrance exams to enter professional programs. Students looking to apply to these health professional programs need to take their respective entrance exams [DO (MCAT), MD (MCAT), Podiatric Medicine (MCAT), Dental (DAT), Optometry (OAT), and Physician Assistant (PA-CAT)]. All students applying to these programs should plan to take this course as a Junior or Senior at Saint Mary’s before taking their entrance exam. Furthermore, this course will teach students “next level” study strategies and time management skills required to be successful in professional school. Prerequisites: BIO 155, BIO 156, BIO 157, BIO 158, or BIO 141 and BIO 142; CHEM 121, CHEM 122, CHEM 221; MATH 104 or higher (math course needed for professional program should have been taken).

Four Year Plans in Biology

Students who major in Biology at Saint Mary’s College can choose from three different concentrations:

  • Integrative
  • Cellular/Molecular Biology
  • Ecology, Evolution, and Environmental Biology

The sample Four-Year Plans presented here are for the Integrative Concentration and show how one might progress through the major if they are:

(A) Math Ready – ready to enter directly into Calculus

(B) Math Ready and Studying Abroad – you CAN study abroad as a Biology major! We recommend going during Sophomore Year Spring or Junior Year Fall for Biology majors; the example shown is for study abroad Junior Year Fall.

(C) Math Wait – the student delays the start of calculus by choice or due to need to take additional math courses to prepare for calculus

Students in Biology generally complete their Sophia LO2 (other than the CTS course) and LO3 requirements outside of the major, although some of our upper level Biology course options include Global Learning, Social Responsibility, Women’s Voices, or Academic Experiential Learning attributes.

Students interested in Individualized Advising or Four-Year Plans for the other concentrations in Biology should contact the Chair of the Biology Department.

**

Students who place into Pre-Calculus are encouraged to replace the non-language Sophias listed in the first year with MATH 103 Precalculus in the fall and MATH 131 Calculus I in the spring. They would then take  MATH 132 Calculus II in the fall of Sophomore year and make up the two displaced Sophia courses in the remaining semesters in place of electives.
