Elective courses (18 credits): The remaining 18 credits should be graduate level physics or materials electives, or graduate level courses in a related field with approval of the research supervisor and graduate program advisor. One of the electives must be a computational course (PHYS 6170 Computational Physics and Engineering, MPEN 6290 Computational Materials Science and Engineering, or a computational course in another department approved by the graduate program advisor). Up to 6 credits may be fulfilled by Advanced Research I and II, with approval of the research supervisor and graduate program advisor. Advanced Research I and II may be taken at the same time as Research I-IV, with up to 6 credits of research allowed in one semester.
