Kit Windows-Yule is a Lecturer in Chemical Engineering, working jointly with the School of Physics and Astronomy’s Positron Imaging Centre.

Kit’s research interests concern the dynamics of particulate systems, in particular their segregative and convective behaviours, and the development of novel experimental and numerical methodologies through which these systems can be explored.

Using techniques such as Positron Emission Particle Tracking (PEPT), X-Ray Tomography, Particle Tracking Velocimetry (PTV), and Discrete Element Method (DEM) modelling, Kit has studied a diverse range of particulate and multiphase systems, including vibrofluidised and gas-fluidised beds, high shear mixers, rotating tumblers, hopper flows and microgravity systems – which he has been lucky enough to explore both in simulation and experimentally.

Kit is also a part of the Birmingham Plastics Network, an interdisciplinary team of more than 40 academics working together to shape the fate and sustainable future of plastics.  This unique team brings together chemists, environmental scientists, engineers, philosophers, linguists, economists, artists, writers, lawyers, and experts in many other fields, to holistically address the global plastics problem.


  • PhD in Physics, University of Birmingham, 2015
  • MSci Physics, University of Birmingham, 2010


Kit Windows-Yule graduated with an undergraduate Masters in Physics from the University of Birmingham in 2010 and stayed on to complete his PhD, studying under Professor David Parker in the University’s Positron Imaging Centre (PIC), in 2015. During this time, Kit became an expert in the application of positron emission particle tracking (PEPT) to the study of granular and particulate media.

Following his graduation, Kit travelled to the Netherlands to work in the University of Twente’s Mechanical Engineering faculty, where he acquired a knowledge of numerical methods, in particular the discrete element method (DEM), providing a valuable complement to the experimental methodologies learned in Birmingham.

In 2017, Kit undertook his second postdoctoral post in the Chemical and Biological Engineering institute at the Friedrich-Alexander Universität Erlangen-Nürnberg, Germany, adding to his repertoire further experimental techniques, including x-ray tomography, x-ray radiography and particle tracking velocimetry (PTV).

Finally, in 2018, he returned to his Alma Mater, to take up his current post as Lecturer in Chemical Engineering.


  • 3rd year Multiphase Systems, MS3
  • Foundation year skills


Kit specialises in the experimental imaging and numerical simulation of granular media, powder flows and multiphase systems. He studies particulate systems both from a fundamental and applied standpoint, collaborating both with academic institutions and industrial entities, as well as actively developing the techniques used to study these systems.

Kit has explored, and continues to explore, a range of diverse research topics and systems, including:

  • Granular segregation
  • Granular convection
  • Combined experimental-numerical study of powders, granulates and multiphase systems in rotating drums, vibrofluidised beds and gas-fluidised beds
  • Development of novel applications and capabilities for Positron Emission Particle Tracking
  • Development of novel particle tracking algorithms for x-ray-based and optical imaging techniques
  • Development of DEM models for diverse particulate systems
