Science Core Elective Courses (6 credits)

Electives can be graduate-level courses offered throughout the University. 

A preliminary exam is taken at end of year 1 that tests the student’s general knowledge base in Medical Sciences and their ability to critically evaluate scientific literature. The preliminary examination includes a written component followed by an oral component on a separate day.

A candidacy exam is taken at the end of year 2. The student will prepare a written and oral proposal for dissertation research that meets the requirements for an external grant proposal. The oral proposal meeting will include both a defense of the student's proposed research and an in-depth examination of the student's knowledge of their research specialization.

When the dissertation research is complete, all Medical Sciences faculty and students will be invited to attend the oral dissertation defense meetings. Following the oral presentation and questions from faculty in attendance, the Dissertation Committee will meet separately and vote on the outcome. The outcome will be presented to the student, along with any conditions or requirements for proposal or dissertation revisions. 

The 2023-2024 UD graduate student tuition rate per credit hour is $1,028.

Research Assistant awards will be made for students that best fit the needs of the sponsoring faculty member. Teaching Assistant awards will be made for students prepared to teach and otherwise assist with undergraduate instruction.

Students can also apply for internal funding, such as the competitive awards offered through the UD Research and Graduate Studies Office. Students can also apply for pre-doctoral support from external funding agencies. The sponsoring faculty member will work with the student to develop the proposal.
