B.S. in Biology
![]() |
Loyola's Bachelor of Science (B.S.) in Biology degree program offers a myriad of undergraduate student research opportunities. The program's reputation also has enabled students to secure internships in hospitals, at medical equipment companies, zoos, biotech companies and many other employers. Loyola students recommended for admission by the Pre-Health Professions Advisory Committee have nearly an 80% acceptance rate into health professional schools, which is nearly double the national average of 45%. This also attests to the caliber of Loyola's Biology program. |
