Dr. Silviya Halacheva joined the University of Bolton as a Lecturer in Chemistry in 2013. In Bolton her academic responsibilities covers preparation and delivering of lecture materials in chemistry, biomaterials science, nanotechnology and medical devices. She is a program leader of the new undergraduate courses in chemistry. Dr. Halacheva is also expected to develop strong research portfolio in the area of biomaterial science. She is currently co-supervises one PhD student and is a director of studies of a second one on multi-responsive gels and coatings.
Dr. Silviya Halacheva received her PhD degree from the Bulgarian Academy of Sciences in 2008. Before joining the University of Bolton she has worked as a postdoctoral research assistant at the Chemistry Department, University of Bath from 2007 to 2009, the Physical and Theoretical Chemistry Research Laboratory, University of Oxford from 2009 to 2012 and at the School of Materials, University of Manchester from 2012 to 2013. The main focus of her research in Bath was in the area of polymer synthesis and characterization, and the study of nanoscale structure formation in self-assembling systems, ranging from surfactant micellar structures to block and graft non-ionic and ionic polymers. In Oxford she investigated the spontaneous self-assembly, of novel and unique nanostructured multilayers from polyamine/surfactant mixtures at the air/water interface by employing neutron reflectivity and surface tension. Her research in Manchester explored the potential use of hollow particle gels as injectable dispersions for in-vivo repair of cartilage tissue.
Dr. Halacheva is a co-author of several successful research beam-time proposals, obtaining funding for the use of a number of neutron reflectivity and small angle neutron scattering instruments in UK, Germany and France. She has many publications in high impact factor peer-reviewed journals. She has given talks in several international and national research meetings and received two international awards for her achievements in the area of smart polymer colloids. Dr. Halacheva is regularly invited to review international peer-reviewed research articles.
