Several RA/PhD/Postdoc vacancies on computational materials and physics are available.
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/. Usually there are two batches (October-November; January-February) for application for Autumn admission.
Postdoc candidates are encouraged to apply the following two types of Postdoctoral centrally funded by University of Macau:
a). UM Macao Postdoctoral Fellowship (UMPF, Class A): Monthly remuneration of MOP40,000 (taxable). Annual conference and research related trips allowance of MOP20,000; Maximum contract period of 2 years.
b). UM Macao Postdoctoral Associateship (UMPA, Class B): Monthly remuneration of MOP28,000 (taxable). Annual conference and research related trips allowance of MOP14,000, Maximum contract period of 2 years.
The UM Macao Postdoctoral Fellowship and Associateship are awarded to PhD degree holders who have graduated within 2 years, or PhD students who are expected to graduate within 6 months from the application date.
Applicants should have proven record of outstanding academic achievements, including publications, and academic awards etc.
Applicants for UMPF should possess a PhD degree from top ranked universities or disciplines (i.e., Top 200 ranked universities listed in the THE/QS ranking, or those listed under the Double First-Class Initiatives and Programs in Mainland China).
