Several RA/PhD/Postdoc vacancies on computational materials and physics are available.

PhD:

The candidate should have obtained grades in his/her Bachelor and Master educations with solid background in solid state physics and quantum mechanics. Any programming experience (e.g. Python, Matlab, and Fortran) will be an advantage.

(1) There are two types of PhD stipends provided by the UM:

  • UM Macao PhD Scholarship: UM Macao PhD Scholarship provides each awardee with a monthly stipend of MOP20,000 for a period up to 4 years.
  • The PhD Assistantship: The PhD Assistantship, supported by either UM centralized funding or principal investigator (PI)’s research funding, provides each new recipient with a starting monthly stipend of MOP12,500 (up to MOP14,000).

(2) Application procedures and important dates:

The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled at the Institute of Applied Physics and Materials Engineering (IAPME) at UM. For information about the general requirements for enrollment and the procedures for applications, please see https://grs.um.edu.mo/.
