A postdoctoral researcher position and a Ph.D. studentship are available in the group of Prof. Zhi-Heng Loh at Nanyang Technological University (NTU), Singapore. The postdoctoral position is available from August 2026, while the Ph.D. studentship will commence in August 2027.
The project aims to employ time-resolved photoemission electron microscopy (TR-PEEM) to investigate the electronic structure and ultrafast electron injection dynamics at the 2D material-water interface. Supported by a three-year grant from the Ministry of Education, Singapore, the existing TR-PEEM apparatus at NTU will be upgraded to enable energy- and momentum-resolved TR-PEEM measurements using a femtosecond vacuum-ultraviolet (VUV) light source operating at MHz repetition rates.
The postdoctoral researcher and the Ph.D. student will work closely on designing and assembling the upgraded experimental apparatus; generating and characterizing ultrashort laser pulses spanning the UV to near-IR (pump) and VUV (probe) regions; applying these pulses to time-resolved photoemission electron microscopy and momentum microscopy experiments; developing computer programs for automated data acquisition and data analysis; and collaborating with research partners in the United States and the United Kingdom on theoretical simulations and sample fabrication.
Applicants for the postdoctoral researcher position should possess a Ph.D. degree and a strong track record in experimental physical chemistry, chemical physics, condensed matter physics, or related disciplines. Candidates should be highly motivated and have strong oral and written communication skills in English. Experience in the design and construction of experimental apparatus, ultrafast optics, vacuum technology, and computer programming for automated data acquisition and analysis will be advantageous. The initial appointment is for one year and is renewable annually for up to three years, subject to satisfactory performance and mutual agreement.
Applicants for the Ph.D. studentship should have a B.Sc. or M.Sc. degree in physics, chemistry, or a related field. Candidates should be highly motivated, possess a strong academic record, and have good oral and written communication skills in English. Previous research experience involving laser systems, vacuum instrumentation, and computer programming would be beneficial. The Ph.D. scholarship is tenable for four years, beginning in August 2027, and includes full tuition support and a monthly stipend.
Please direct inquiries to Prof. Zhi-Heng Loh (zhiheng@ntu.edu.sg). Applications should include a brief statement of research interests and motivation; a curriculum vitae; the names and contact information of two referees; and, for applicants to the Ph.D. studentship, an academic transcript. Applications will be reviewed on a rolling basis until the positions are filled.
