We are seeking a Senior Research Fellow to develop high-sensitivity, high-resolution perovskite-based X-ray line detectors for security screening, overseeing both scintillator-film (microcolumnar/light-management) and direct-conversion detection pathways. The role will coordinate materials/device fabrication, characterization and imaging validation (e.g., MTF/SNR, low-contrast detectability), align workplans and interfaces across research and electronics/readout integration teams, and drive integration into tile-able submodules and a scanning demonstrator. Responsibilities include technical documentation and delivery of milestones across the 36-month project, plus contributions to publications, IP and grant proposals. Candidates should hold a PhD in a relevant field with strong experience in perovskites and radiation detection/optoelectronics, hands-on fabrication/characterization capability, and excellent communication; relevant radiation/laser licensing is advantageous.

Key Responsibilities:

• Lead the technical execution of the project workplan from requirements/baselining through prototype module demonstration, coordinating with CNRS counterparts.

• Lead and assist in the fabrication of perovskite/composite scintillator films (optimizing formulation, deposition, optical management, and scalable, repeatable processes) to meet target light yield, decay, spatial resolution, and stability requirements.

• Lead and assist in the fabrication and microfabrication of direct-conversion perovskite X-ray detectors (engineering materials, interfaces, and device architectures).

• Lead and assist comprehensive structural, optical, imaging, environmental, and electrical/radiation-response characterization of scintillation and direct-detection layers to quantify performance, stability, and compliance with imaging requirements, with techniques such as XRD, SEM, optical spectroscopy, I–V/C–V measurements, time-resolved techniques).

• Coordinate with system engineers for system-level integration and testing: optical coupling or charge readout interfacing to commercial line sensors / backplanes, packaging/encapsulation, and final testing and validation.

• Support end-to-end detector module builds, from materials fabrication through packaging and system-level imaging tests (phantoms, resolution targets).

• Own project reporting and technical documentation.

• Mentor and supervise students and junior staff; establish safe laboratory practices for radiation/laser/chemical work, and support procurement and lab operations.

• Work closely with interdisciplinary teams in materials science, physics, and device engineering.

• Contribute to proposals and IP generation, high-impact publications, reports, and presentations; mentor junior researchers; and support laboratory operations and safety.

Job Requirements:

• PhD in Physics, Materials Science, or a closely related discipline.

• Effective problem-solving skills.

• Demonstrated at least 5 years of experience in research with the focus on X-ray detection (scintillators and/or direct-conversion)

• Hands-on micro/nanofabrication expertise: cleanroom processing, photolithography/nanolithography, thin-film deposition of solution-processable materials, and thermal/e-beam evaporation (metals/small molecules).

• Perovskite materials synthesis & growth capability, including inert-atmosphere glovebox processing (e.g., spin coating), perovskite (nano-)material synthesis, and crystal growth.

• Experience in perovskite device fabrication (e.g., diodes and FETs), and characterization (I–V/C–V, impedance spectroscopy)

• Materials characterization expertise (XRD, SEM, AFM, spectroscopy, time-resolved techniques).

• Strong publication record and experience with proposal writing, technology translation, and IP generation.

• Excellent communication and collaboration skills, able to work effectively in interdisciplinary and international teams; independent, proactive problem-solver and team player.

• Strong presentation and reporting skills to stakeholders

• Familiarity with laboratory safety management; ability to work in regulated environments (e.g., ionizing radiation/laser/chemical handling).

• Relevant certifications (NEA N3 and R1 licenses) is advantageous.
