For the PhD degree, it is expected that a minimum period of four years be devoted to full-time study, including dissertation research and defense.
Between 10 and 20 graduate students are enrolled in the department during a calendar year. Career choices are varied, but most students prepare for positions in teaching and research at the university level.
The minimum core requirements of all PhD candidates are:
| INTER 111 Biochemistry | 4 credits |
| INTER 121 Cell Biology | 3 credits |
| INTER 122 Molecular Genetic Mechanisms | 2 credits |
| INTER 123 Control of Gene Expression | 2 credits |
| INTER 220 Ethics in Biomedical Sciences | 1 credit |
| INTER 260 Responsible Conduct in Research | 1 credit |
| MICRO 228 Laboratory Rotations in Microbiology | 6 credits |
| MICRO 225 Bacterial Pathogenesis | 4 credits |
| MICRO 296 Fundamental and Advanced Immunology | 4 credits |
