Positron Emission Particle Tracking (PEPT)

PEPT is an experimental method capable of visualising the 3D motion of particles in opaque fluids and casings, e.g., flow of liquid metal or of blood inside the human body. Collaborating with Prof. Tzany Kokalova Wheldon and Dr. Kit Windows-Yule from the University of Birmingham, we work on applying PEPT to study the dynamics of droplets suspended in fluid.

 

Collaborating with Prof. Jacques Vanneste from The University of Edinburgh, we derive a mathematical model to quantify the uncertainty in reconstructing particle trajectories in PEPT, and conduct a Bayesian analysis using Markov Chain Monte Carlo (MCMC) simulations to minimise the measurement uncertainty.
