PhD Position: Nonlinear Optical Characterization of Chiral Surfaces KU Leuven in Belgium

This PhD position at KU Leuven focuses on the nonlinear optical characterization of chiral surfaces, conducted within the Molecular Electronics and Photonics Lab (MEP) of the Department of Chemistry. The successful candidate will join the CHIRALNANOMAT Doctoral Network (MSCA – Horizon Europe), a collaborative European training program in nanoscience and nanotechnology.

The research will investigate the nonlinear optical properties of size-selected metal clusters in solution using advanced techniques such as polarization-resolved second and third harmonic scattering and circularly polarized hyper-Rayleigh scattering. A significant part of the project will involve studying chiral surfaces composed of nanostructures, employing coherent second-harmonic generation to analyze surface organization, chirality, and symmetry, complemented by advanced spectroscopic measurements. The position offers a stimulating and diverse research environment at KU Leuven, a leading European university recognized for its research excellence.

The CHIRALNANOMAT network provides comprehensive training, including local expert training, network-wide secondments, and a series of seminars, workshops, and schools, ensuring doctoral candidates gain cross-cutting expertise valued in both academia and industry. The candidate will primarily work in Leuven, with short research stays at Technische Universität Wien, University of Geneva, and Invisible Light Labs GmbH for specialized training.

Applicants must hold a Master’s degree in physics, chemistry, optics, or a related field, demonstrate English proficiency at B2 level or higher, and have strong academic records. Experience in optical setup design, nonlinear optical techniques, and basic knowledge of chemistry and spectroscopy are required; programming skills are advantageous. Candidates must comply with the MSCA mobility rule, meaning they should not have resided or worked in Belgium for more than 12 months in the 36 months before recruitment.

The position is fully funded according to MSCA regulations, including salary and benefits. KU Leuven is committed to diversity, inclusion, and equal opportunity. The application deadline is November 20, 2025.
