DOCTORAL PROGRAM IN BIOLOGY
The PhD program of the Río Piedras Campus is offered in conjunction with the Medical Sciences Campus and the Institute of Tropical Ecosystem Studies.
In addition to the requirements for admission to graduate studies at the Río Piedras Campus and in the College of Natural Sciences, the Department of Biology requires the following:
- A master’s degree in science or the equivalent. Students who have shown special promise in research may be considered for admission after having completed the Bachelor of Science degree;
- Courses required for admission to the masters program;
- An interview with the Admissions Committee, if required;
- Scores on the Graduate Record Examination (GRE) General Test; Subject Test in Biology, or Biochemistry, Cell and Molecular Biology is recommended but not required.
Advancement to candidacy for the doctoral degree will be considered once the student has passed both the written and oral parts of the comprehensive examination and has successfully defended the dissertation proposal.
In addition to completing all requirements for graduation from the Río Piedras Campus, students must complete the following:
- 60 credits with a minimum grade point average of 3.00 at both the Río Piedras and Medical Sciences Campuses, including a minimum of 18 credit hours in research;
- a minimum of two semesters (consecutive or non-consecutive) as a teaching assistant for all students with no previous university teaching experience.
Program of Study
Students’ academic programs will be prepared in consultation with their academic advisors.
