Research on hydrogen interaction with materials and surface analysis using laser-based diagnostics. Supervising students and teaching undergraduate physics. Collaborating with Kyushu Univ. and NIFS. Full project: Hydrogen Getter Films.

Studied impurity flows in the edge plasma of the Large Helical Device using a high-resolution Echelle spectrometer. Developed a custom Python tool to process raw spectrometer images. Analyzed molecular hydrogen emission and isotope effects on carbon transport.

Developed a novel permeation probe to measure atomic hydrogen flux to fusion device walls. Applied it in the QUEST tokamak to study gas balance and discovered significant hydrogen retention at far wall locations shielded from direct plasma exposure.

Developed and patented a novel radiographic filter that enhances resolution in non-destructive inspection. Now implemented in the production of fission reactor fuel assemblies.

Collaborated with the Tore Supra team to improve glow-discharge cleaning for tokamak operation. Proposed a new scenario that significantly increased efficiency and reduced cleaning time. Designed a multi-species deposition device for tungsten-carbon thin films, later upgraded for safe boron-carbon film deposition. My prototype informed the development of an advanced system used to optimize boronization for the ITER project.

Earned my M.Sc. and Ph.D. while working in this lab, gaining hands-on experience with vacuum and plasma systems. Investigated hydrogen retention in plasma-facing components of the Tore Supra tokamak. Found significantly higher retention in in-vessel graphite tiles compared to lab-exposed samples, identifying the amorphous surface layer as the main retention site. Later contract work revealed that trace oxygen in the gas mix dramatically increases hydrogen retention.
