Gabriel Leen

Gabriel Leen serves as a Senior Research Fellow in the Department of Electronic and Computer Engineering within the Faculty of Science and Engineering at the University of Limerick. His research integrates optical engineering, acoustics, and biomedical applications to develop advanced sensing technologies for medical diagnostics and industrial processes.

Dr. Leen's primary research focuses on optical fiber sensor systems for pressure, temperature, and refractive index measurements, with significant applications in urodynamic analysis, radiotherapy dosimetry, and respiratory monitoring. His pioneering work in acoustic levitation enables contactless sample manipulation for X-ray crystallography, reducing sample consumption while enabling time-resolved structural studies of biological macromolecules. This interdisciplinary approach bridges physics, engineering, and clinical medicine through innovative device fabrication and signal processing techniques.

Analysis of his recent publications (2023-2025) reveals three dominant research trajectories: 1) Acoustic droplet manipulation systems for X-ray light sources enabling new crystallography methodologies; 2) Miniaturized optical fiber sensors with biocompatible designs for in vivo medical applications; and 3) Laser-based processing techniques for flexible electronics and sensor fabrication. These themes demonstrate consistent innovation in translating fundamental physical principles into practical biomedical instrumentation with clinical impact.
