Barbara Urasinska-Wojcik

Barbara Urasinska-Wojcik graduated in 2004 with a M.Sc. degree in Materials Science Engineering from Wroclaw University of Technology in Poland. During her degree project, she studied the spectroscopic properties of sulfonated aluminium phthalocyanines in aqueous solutions and their applications for photodynamic therapy. She studied for a Ph.D. with Professor Geoff Ashwell in the Nanomaterials group at Cranfield University, before transferring to the University of Wales, Bangor. During her Ph.D. she focused on the design, preparation and characterisation of molecular diodes from new types of organic junctions and also the electrical characterisation of molecular wires. Her paper on the molecular diodes and the molecular wire have attracted much attention and were designated as “Hot Articles” by the Royal Society of Chemistry and received “Top Ten” listings on the RSC website. They have also received reviews in Chemistry World, Chemical Science and Utilise Gold Bulletin and were highlighted in several other countries. Her research as a postdoctoral research officer within the College of Physical and Applied Sciences at Bangor University involved organic photovoltaic materials, electrical and optical characterisation of organised molecular films and single molecule electronics.

In November 2010, Barbara took up her role as a Project Scientist in the research group of Professor Michael Turner. Barbara is a part of the Knowledge Centre for Materials Chemistry (KCMC) and is currently working on fabrication and characterisation a range of organic semiconductor devices (mainly OPVs and OFETs).
