Sebastian Pont is researching machine learning techniques with neutron scattering measurements to predict polymer-polymer demixing processes with Prof João Cabral, collaborating with Prof Nigel Clarke from Sheffield University. The practical applications of polymeric bicontinuous structures include organic photovoltaic cells, bio-scaffolds and separation membranes. Here we enable predictions of the demixing lengthscale to enable precise design for these applications.

Dr Pont completed his PhD under the supervision of Prof James Durrant and Prof João Cabral within the Centre for Doctoral Training in Plastic Electronic. His research focus is on understanding the morphological and chemical stability of organic and perovskite photovoltaics using a range of modelling and data-focused techniques combined with spectroscopic and material characterisation.

Previously, he obtained an MRes with distinction in Plastic Electronics at Imperial College London and a First class MEng in Chemical Engineering from Loughborough University which included a placement at the University of Minnesota Duluth, USA.
