Biography

Siew Yan Hoh obtained his PhD in Experimental Particle Physics from the University of Padova in 2021. He has held research appointments at CERN, Fermilab, INFN Padova, the National University of Malaysia, and the Tsung Dao Lee Institute at Shanghai Jiao Tong University. He is a data analyst and experimental particle physicist with extensive experience in scientific data analysis, simulation, and data engineering for large-scale physics experiments. His research spans the CMS experiment at CERN, where he contributed to dark matter searches and precision measurements of the Standard Model Higgs boson, and precision muon physics through postdoctoral work on the Muon g-2 experiment at Fermilab, focusing on beam dynamics, muography, and high-precision dipole moment measurements. He is currently an Associate Professor at Xiamen University Malaysia. His research interests include applied muon physics, laser–plasma acceleration, and data-driven methods in high-energy physics, with an additional focus on physics education and outreach using real experimental data.

Research Interest

• Experimental High Energy Physics: Exploring fundamental particle interactions through precision measurements and searches for new physics beyond the Standard Model, with a focus on the intensity frontier (rare processes), energy frontier (high-energy colliders), and muon physics (Precision Measurement).
• Laser Wakefield Acceleration: Investigating high-gradient plasma-based acceleration techniques using ultra-intense laser pulses to generate compact, high-energy electron beams, with potential applications in producing electron-driven muon sources for particle physics experiments and application in condense matter.
• Physics in Data and Education: Engaging students and the public through hands-on cosmic-ray experiments and CERN Open Data, using real physics data to promote scientific curiosity, data literacy, and experiential learning.
