MASTER OF SCIENCE PROGRAM

The M.S. program in Chemical Engineering comprises 24 credits of course work and a thesis. The total number of credits is composed of 15 credits of required courses and 9 credits of elective courses to be chosen from among the graduate courses offered by the program or the Institute, subject to the approval of the student's advisor. The required courses are designed to provide a uniform background covering fundamental areas:

Students who have already taken CHE 555 in their undergraduate program may instead take elective courses approved by their advisor. Candidates who have not taken any process control course during their undergraduate studies must complete CHE 475 Process Dynamics and Control, without credit, with the approval of their advisor.

DOCTOR OF PHILOSOPHY PROGRAM

The Ph.D. program in Chemical Engineering is composed of a minimum number of 24 credits of course work and a dissertation carried out according to the regulations of the Institute. Ph.D. students are assumed to have taken the courses required for the M.S. program, or their equivalents, and should complete the following 6 credits of required courses:

The remaining part of the course work is planned under the supervision of an advisor and is composed of courses chosen from among the graduate courses offered by the program or the Institute to suit the student's specific objective.
