Two postdoctoral positions are available at the Ultrafast Optoelectronics Lab (UOLB) of the Institute of Applied Physics and Materials Engineering (IAPME) in the University of Macau.

The successful candidates will be involved in developing and applying ultrafast nonlinear spectroscopic techniques to a variety of important optoelectronic systems for both fundamental physical studies and applications. These techniques will afford a prerogative opportunity to quantitatively explore the individual photo-physical and photochemical processes with high spatial, spectral and temporal resolution.

Our candidates are expected to have a PhD degree in physics, materials science and engineering, ultrafast laser science or related field with experience in one or more of the following areas: metal halide perovskites, light harvesting and light emission, ultrafast nonlinear spectroscopies, quantum confined systems, or two dimensional materials.

These positions carry competitive salary (US$54K/year, or RMB360K/year) and benefits initially for two-year term, may be renewable depending upon future funding situations and performance of the candidates. Interested candidates should forward a CV with name and contact information of two references to We will start reviewing applications and continue that until the positions are filled.
