Postdoctoral Researcher – Nanoscale Thermal Transport International Iberian Nanotechnology Laboratory in Portugal

The International Iberian Nanotechnology Laboratory (INL) in Braga, Portugal, is seeking a postdoctoral researcher to join the Sotomayor Research Group for a 24-month, full-time position focused on nanoscale thermal transport. The group, led by Professor Sotomayor Torres, is internationally recognized for its research in nanophononics, including nano-scale thermal transport, phononic crystals, opto-mechanics, thermoelectricity, acoustic metamaterials, topological bosonics, and NOEMS. The successful candidate will contribute to the SPARK-e project, funded by Horizon Europe, and collaborate on several other high-profile projects such as MUSICIAN, LEIT, MAGNIFIC, and NEUROPIC.

Key responsibilities include conducting experiments and data analysis, advancing experimental methods for studying thermal transport in nanostructured and emerging materials, building and optimizing ultrafast laser-based setups for time- and frequency-domain thermoreflectance (TDTR) measurements, and performing thermal mapping and imaging experiments to probe local heat transport and phonon dynamics. The role also involves finite element modeling (FEM) using tools like COMSOL Multiphysics to simulate thermal transport processes, disseminating research results through publications and conferences, and contributing to equipment maintenance and safety compliance. Applicants must have a PhD in Condensed Matter Physics, Material Science, or a related field, with postgraduate research experience in semiconductor and nanoscale devices, particularly in phononic crystals and nanoscale thermal transport.

Essential skills include hands-on experience with ultrafast laser systems for time-resolved optical measurements, material characterization, and finite element analysis. Additional experience with data analysis (Matlab, Python) and interfacial thermal transport is highly valued. Candidates should demonstrate strong problem-solving skills, the ability to work independently and as part of a team, and excellent communication skills in English. INL offers a competitive salary, tax benefits, private health insurance, family allowances, free nursery service (subject to availability), support for dependent children's education fees, relocation support, and 30 working days of annual leave.

The application process requires submission of a cover letter, CV, academic/professional diplomas, and at least one reference letter, all in English and in PDF format, via the online application portal. The selection process includes eligibility checks, CV assessment, interviews, and final nomination. INL is committed to equal opportunity and non-discrimination.
