GDB Courses and Degree Requirements

The Global Disease Biology (GDB) academic major provides students with broad preparatory scientific course work, GDB core courses, flexibility in upper division electives, and a strong research experience. The GDB core courses (GDB 90, SAS 13, PMI 129Y, VME 158, GDB 101, GDB 102, and GDB 187) are intended to be transdisciplinary and focus on concepts that cut across human, animal, and plant diseases offering a unifying ecological and quantitative perspective on disease. Students will also be required to take a minimum of two pathogen courses, although they can certainly take more as restricted electives.

These classes provide depth on specific pathogen groups (e.g., bacteria, viruses, fungi, macroparasites) or diseases of specific hosts (e.g., plants, animals). Students prepare for their GDB junior and senior year through a required discussion course (GDB 187) and are encouraged to customize their GDB experience by putting together, in consultation with their faculty advisor, an interest-driven set of GDB restricted electives. Students may draw from many undergraduate and even graduate-level courses currently offered on disease and health in a way that compliments the core courses required for the GDB major.

The major also includes a senior research project (GDB 189) that involves 1 or 2 quarters of independent study or research under the guidance of a faculty mentor. Projects may be off campus with a non-UC Davis mentor, but students must also have an on campus faculty member as a co-mentor.

GDB Core Course Descriptions

Quantitative analysis of both infectious and non-infectious disease. Inter-dependence between epidemiological analysis, decision-making and policy formulation will be highlighted.
GDB 102: Disease Intervention and Policy (4 units)
Lecture - 3 hours, Discussion - 1 hour. Examination of the prevention and treatment of diseases affecting humans, animals, and plants. Case studies will illustrate the merits of a unified approach to promoting health at local, regional, and global scales.
GDB 187: Global Disease Biology Seminar (3 units)
Seminar - 1 hour; discussion - 1 hour; term paper. Prerequisite: GDB 90, SAS 13. Open to junior standing; Global Disease Biology majors. Seminar leading to development of the research proposal and academic plan for the Global Disease Biology major.

Requirements for a Bachelor of Science (B.S.) degree in Global Disease Biology

The GDB degree requirement includes 64-66 units of Preparatory Subject Matter, 44-47 units of Depth Subject Matter, and at least 25 units of Restricted Electives, for a minimum total of 133-138 units. Students transferring from a community college, state college, or another university are encouraged to contact our GDB academic staff (gdb-advise@ucdavis.edu) with questions about if and how their UC-transferable units might waive one or more GDB course requirements. A degree in GDB from UC Davis covers the standard prerequisites for many health profession schools (e.g. medical school, veterinary medicine, physician assistants, nursing, dental school, physical therapy, clinical lab sciences), but additional requirements may exist, for example additional quarters of Organic Chemistry and Physics; we recommend that students wanting to follow these career paths plan accordingly and check with individual schools and consult campus resources (e.g. http://hpa.ucdavis.edu/prehealthrequirements/index.html). Students may also chose to minor in GDB; requirements are listed at the bottom of this page.
