Biography
Tim (BEng CEng MIMechE
FHEA) is Professor of Fluid Mechanics and acted as Head of Department of Mechanical
& Energy Systems Engineering until July 2021. He is also Deputy Director of
the IRC in Polymer Engineering and Manager of their Materials Characterisation
laboratories.
His main research
interests are in the effects of flow upon materials development for polymeric
and pharmaceutical applications. His current work involves the application of
optical, spectroscopic, neutron and x-ray probes to soft matter and
pharmaceuticals undergoing deformation and crystallisation to elucidate the
effects of shear on structure and its influence on processing and end product
properties. He is a frequent user of large-scale international neutron and
x-ray facilities in the UK, France and the US to aid with these studies.
He holds a first degree in
Mechanical Engineering and a PhD in Fluid Mechanics from the University of
Surrey for his work on turbulent boundary layers and wakes. Following this he
moved to Bradford to work projects on cyclonic two-phase separations for the
brewing and oil industries prior to working on the two large EPSRC funded
Microscale Polymer Processing programmes.
He has many active links
with industry and academia in the fields of polymer processing and
pharmaceutics and holds three patents in these areas.
He has supervised 13 PhD
and 2 MPhil students to completion and currently supervises four PhD students
in the fields of fluid mechanics, hydrogels and pharmaceutical processing. He
was awarded the University’s Baroness Lockwood Award for Distinguished Teaching
in 2010 and was especially pleased to be awarded Lecturer of the Year in the
inaugural UBU Student Leadership Awards in 2019.
Tim has published over 50
peer-reviewed journal papers as well as over 100 conference papers in polymer
science, engineering, separations technology and aerodynamics.
