Without a doubt, the Biology degree is the most versatile of the many degrees in the life sciences. Over half of our majors (in all of our degrees) go on for an advanced degree such as the Master of Science or the Doctor of Philosophy (Ph.D). Historically, Biology has placed more of its majors in medical and dental schools than any other department at Texas A&M. In addition, a large number of our majors complete teaching certification in order to take positions as science teachers in secondary schools. Qualified science teachers continue to be in high demand, giving the applicant options to go to nearly any area of the state or country where they might choose to live. Business, industry, and government continues to hire many of our graduates where skills and knowledge in the life sciences are in great and growing demand. Furthermore, training in Biology provides a unique perspective in other professions such as Law, Architecture, Engineering, Business and Management.
An important aspect of the Department of Biology is that it offers a wider array of degrees than other departments at Texas A&M. This permits students to specialize in an area of particular interest while working toward their career goals. The Department offers seven undergraduate degree programs, which are outlined below. Detailed information about the degree plans described below is available from the Office of Undergraduate Advising.
Having a career goal in mind enables students to choose the most appropriate undergraduate curriculum and electives. Keep in mind: some careers in biology require advanced or specialized training.
The first two years of any major in biology is quite similar. All incoming freshmen must complete the following courses within the first two years of his/her program: BIOL111, BIOL112, BIOL213, BIOL 214, CHEM101/111, CHEM102/112, CHEM227/237, CHEM228/238, MATH147 (or 151 or 171), and MATH148 (or 152 or 172). Transfer students are admitted only after completing the first year of General Biology, General Chemistry, and Calculus. These students have one year upon transferring to complete BIOL214, BIOL214, CHEM227/237 and 228/238.
B.A. in Biology
The Bachelor of Arts (B.A.) degree program, through the availability of a large number of electives, gives the student a broad base in biology. A minor for the B.A. degree usually requires a minimum of 18 hours, 6 or which must be in advanced courses and in a discipline other than biology. The B.A. program is recommended for students who intend to pursue further education in completion of requirements for teacher certification.
B.S. in Biology
The Bachelor of Science (B.S.) in Biology is designed so that students obtain a comprehensive, solid foundation in the branches of biology combined with a suitable measure of individual flexibility. This degree plan is recommended for students seeking teacher certification, preparing for biological graduate programs or any professional program (medicine, dentistry, etc.)
B.S. in Microbiology
The degree program in microbiology if designed to provide a comprehensive education in the biology of microorganisms. A graduate of this program will have a thorough grounding in the classical areas of microbial physiology and biochemistry, microbial genetics, and in developing areas such as the molecular biology of microorganisms. This curriculum provides excellent training for a career in any one of many areas of industrial microbiology and public health services. It is also an ideal preparation for advanced study or professional school in medicine, dentistry and other related fields, especially medical technology.
B.S. in Molecular & Cell Biology
Students who select molecular and cell biology as their major will receive a strong background in the cellular and molecular aspects of biology with a particular emphasis on higher organisms (eukaryotic plants and animals). This major provides an appropriate foundation for a career in biotechnology, genetic engineering, M.D./Ph.D. programs or basic biological research.
B.S. in Zoology
Zoology deals with all aspects of the study of animals from physiology and anatomy to ecology and systematics. Students with this baccalaureate degree may obtain employment directly in teaching, environmental firms, laboratories, etc. Many graduates enter into advanced studies in zoology, into specialized fields in agriculture and renewable resources, or into such professional fields as medicine, dentistry, medical technology and other health-related areas. The B.S. degree in Zoology is also awarded to students who complete the three year Early Admission Option to Professional Schools and one year of professional school.
Undergraduate Program for
Biological and Mathematical Science
A collaboration between the departments of Biology, Mathematics and Statistics with broad participation among faculty in several Colleges across campus. The goal of this program, funded by the National Science Foundation, is to train students in quantitative approaches, including mathematical, statistical, and computational techniques, to fundamental problems in the life sciences. For more information, visit http://math.tamu.edu/ubm/.
Texas high schools are in need of qualified teachers in math and science. Please go to http://aggieteach.tamu.edu/ to learn more about how you can become a high school science teacher and earn your degree in Biology without having to take any extra courses.
