Sebastian Galer

Dr Sebastian Galer is an Associate Tutor in the School of Mathematics and Physics at the University of Surrey. His work bridges applied physics and medical physics, with a focus on radiation detection and simulation for particle therapy applications.

His research centers on advanced detector systems and computational modeling in radiation physics. Key areas include:

• Development of superconducting detectors such as SQUIDs and micro-calorimeters
• Microdosimetry using Tissue Equivalent Proportional Counters (TEPC)
• Monte Carlo simulation of particle beams using Geant4
• Thermal modeling of energy deposition in multi-layer detectors via COMSOL
• Fabrication of nanobridge Josephson junctions using Focused Ion Beam (FIB) techniques

The trend across his recent publications shows a strong emphasis on improving the accuracy of energy deposition measurements in particle therapy, particularly for carbon ions and protons. His work integrates experimental detector design with high-fidelity simulations to correct for real-world thermal and absorption effects, aiming to reduce uncertainties in Relative Biological Effectiveness (RBE) estimates. This interdisciplinary approach combines physics, engineering, and oncology to advance precision in radiation therapy.

Dr Galer has collaborated extensively with researchers in medical physics and radiation science, including H. Palmans, Karen Kirkby, and Andrew Nisbet. His projects involve coupling Monte Carlo simulations with finite element thermal analysis to model complex detector behaviors. While no grants are explicitly mentioned, his work appears to be embedded in larger experimental and simulation-based initiatives in particle therapy dosimetry.

He is involved in the development and testing of novel microdosimetric detectors, particularly those based on superconducting technologies. These detectors aim to measure energy deposition at the micrometre scale with sensitivities down to 0.4 eV, enabling more precise understanding of biological effects in radiation therapy.
