Our students seek solutions to some of the world’s most complex problems, from finding ways to more efficiently produce fuels and chemicals to improving human health through better drug delivery and new biomaterials.
Ph.D. students typically take about eight courses in their first two years and also become involved as teaching assistants during their second and third years in the program. All of our graduate students are supported financially as they work toward their Ph.D. degree.
Our graduate students must complete the required coursework, write a Ph.D. thesis, and perform satisfactorily on their examinations to earn their doctorate in chemical engineering. We do not admit students into the program with the intention of earning a terminal master’s degree; however, students who have met the requirements may obtain a master’s degree as a milestone on the path to completing their Ph.D. degree. Students typically graduate within five years.
Course work for our Ph.D. students includes a minimum of four 500-level courses in chemical engineering and a minimum of four courses (including at least one 500-level course) in one or two other departments. For additional details on course requirements and selections, we refer interested students to the Graduate Student Handbook. Students who enter the graduate program with a B.S. in a subject other than chemical engineering typically take additional courses before the qualifying exam.
The Ph.D. qualifying examination, taken at the beginning of the second year, comprises an oral presentation of the proposed research including a literature review and a 6- to 12-month research plan. Please note that our qualifying exam does not include a traditional written examination.
The preliminary examination, typically taken before the end of the third year, includes a written research proposal and oral presentation to the examination committee describing preliminary data, a detailed research plan, and a timeline for completion of the dissertation.
The final examination, or the dissertation defense, is a significant milestone in a graduate student’s career. This stage involves the student presenting their work to their doctoral committee and disseminating their work to the public. More information about the final exam/dissertation defense, including deadlines, thesis writing guidelines, and assembling a committee for the final defense is provided by the Graduate College Thesis Office.
Questions about the program and its requirements may be directed to our Graduate Program Coordinator.
Coursework for our Ph.D. students includes a minimum of four 500-level courses in chemical engineering and a minimum of four courses (including at least one 500-level course) in one or two other departments.
