The zoology major is a gateway to the diverse areas of modern biology. The major can be tailored to prepare students for advanced study and careers in many different areas: health professions and public health; law; life sciences research in university, government, and industrial settings; education including museum, nature center, secondary school, and college teaching; biotechnology; and environmental studies.

Specialized preparation is offered in ecology, systematics, limnology, morphology, molecular biology, cellular biology, developmental biology, genetics, neurobiology, physiology, evolution, and behavior. Several possible areas, emphasizing different interests, are outlined in the requirements tab. They include ecology, evolution, and behavior; anatomy, physiology, and organismal biology; and cellular, molecular, and developmental biology. The department encourages undergraduate participation in research and offers summer research scholarships to outstanding students.

Goals of the Zoology Major

The zoology major emphasizes critical thinking and conceptual skills that come from an understanding of how scientific information is obtained and evaluated, and of how this information can be applied to societal issues. The major provides a solid foundation in genetic, cellular, physiological, ecological, and evolutionary principles, and in the related disciplines of chemistry, physics, and mathematics. As a result, the major fosters an understanding of biological complexity including the interrelationships among humans and natural systems.

The unique characteristics of the zoology major include:

  • broad-based, yet integrated training in wide-ranging areas of biology;
  • solid foundation of basic principles and processes in biology;
  • flexibility and advising needed to allow students to tailor the major to their specific goals;
  • wide range of opportunities for undergraduate involvement in independent research and senior thesis.

Declaring the Zoology Major

All students who are interested in pursuing the zoology major must schedule an appointment with a department advisor. No major declaration forms are required to declare zoology.

Note: Students in the College of Letters & Science (L&S) may be declared by a department advisor immediately. Students who are not currently in L&S need to either transfer into L&S or have permission from their school or college to pursue an additional major in zoology. Instructions for transferring into L&S are available on the L&S Student Academic Affairs website.

Students are encouraged to consult with a department advisor to construct individual programs appropriate to their own needs. Please use scheduling assistant or call 608-262-2742 to make an appointment with an advisor. Kayla Pelland (kpelland@wisc.edu) is available to meet with students on Monday, Wednesday, and Friday mornings in B154 Birge Hall, and Joel Gruley (jgruley@wisc.edu) is available on Tuesday, Thursday, and Friday afternoons in 156 Birge Hall.

Directed Study

For students interested in a short-term undergraduate research experience in a particular area of zoology, the department offers ZOOLOGY 699 Directed Studies in Zoology. ZOOLOGY 699, recommended for juniors and seniors, is graded on an A to F scale. Students cannot take directed studies on a pass/fail basis.

Directed study allows students to gain experience in a wide range of research areas in biology and to learn research techniques that are not easily taught in the classroom. Such experiences allow students to make more informed decisions about their future goals and careers.

Before students can sign up for ZOOLOGY 699, they must set up an appointment with a professor/mentor of their choice, and work with the professor/mentor to:

  1. decide the specific number of credits and
  2. plan the work required to earn those credits.

Such plans can involve reviewing relevant literature in the area, developing a proposal for independent research, and/or conducting an experiment in the mentor's study area.

Students interested in doing in-depth research as undergraduates in an area of interest can elect to do a Senior Thesis or Senior Honors Thesis (see below). Students should contact a department advisor at the beginning of their junior year to explore possible research areas.

A maximum of 10 credits of directed study (ZOOLOGY 299 , ZOOLOGY 698 , ZOOLOGY 699 ), senior thesis (ZOOLOGY 691 , ZOOLOGY 692 ), or senior honors thesis (ZOOLOGY 681 , ZOOLOGY 682 ) will count toward the 30 credits required for the major.

Senior Thesis

Students interested in making a longer-term commitment to a research project may consider undertaking a senior thesis. Students should contact a department advisor during their junior year to explore possible research areas in zoology.

Zoology Senior Thesis Requirements:

  • approval of a department advisor;
  • completion of ZOOLOGY 691 and ZOOLOGY 692, a two-semester thesis research sequence, during the senior year (6 credits).

It is recommended that candidates for the senior thesis take ZOOLOGY 699 during second semester junior year to prepare for the thesis.

Senior Thesis and Distinction in the Major

Upon recommendation of the department to the dean, Distinction in the Major is granted at graduation to students not earning Honors in the Major who have done superior work in the major. In addition to the requirements for a senior thesis, to graduate with Distinction in the Zoology Major, students must maintain an overall GPA of 3.300 and a GPA of 3.500 in all zoology courses in the major.


The Department of Zoology encourages our majors to begin working on their career exploration and preparation soon after arriving on campus. We partner with the L&S Career Services office to help you leverage the academic skills learned in your major and liberal arts degree, explore and try out different career paths, participate in internships, prepare for the job search and/or graduate school applications, and network with professionals in the field (alumni and employers).

Letters & Science graduates are in high demand by employers and graduate programs. It is important to us that our students are career ready at the time of graduation, and we are committed to your success.
