Joshua Machacek

Dr. Joshua Machacek is a Research Fellow at the Australian National University (ANU) in the Department of Nuclear Physics & Accelerator Applications. He is affiliated with the Positron research group and the He* BEC group, focusing on experimental and theoretical studies of positron interactions with matter.

His research spans positron scattering, atomic/molecular collisions, quantum measurement techniques, and applications in materials science and astrophysics. Key interests include developing positron beam methods, measuring scattering cross-sections, and investigating positronium formation in interstellar environments.

Machacek's recent publications (2018–2024) emphasize positron scattering dynamics, experimental innovations in beam polarization, and positron annihilation spectroscopy. His work is frequently published in journals such as Physical Review Letters, European Physical Journal D, and Nature Communications.

He contributes to collaborative projects on radiation-hardened materials for space and astrophysical positron processes. No awards or advised students are mentioned in the provided data.
