Dorota Bartczak (MEngSc, PhD) is a multidisciplinary scientist with nearly 20 years of active research experience in physicochemical characterisation of nano- and micro-particles with applications in consumer products, medical devices and nanomedicines, as well as on novel contaminants such as nano- and micro-plastics.  She is a Science Area Leader at LGC Limited, with headquarters in the UK.  LGC has been home to the UK Government Chemist for over 100 years and is the UK National Measurement Laboratory (NML) and Designated Institute for chemical and biological measurements. Dorota was educated to a post-doctoral level at the University of Southampton, UK, where she was awarded a PhD in Life Sciences (Nanotechnology) in 2010.  She has received her first degree, Master of Science and Engineering in Biotechnology, at the Technical University of Lodz, Poland in 2007.  Dorota has ~50 peer reviewed publications and book chapters in the nanotechnology area and has received several prestigious awards, including the first prize and Mendel medal in Biomedical Sciences awarded at the House of Commons. She coordinates European Metrology Partnership projects (e.g. 25HLT05 QuanTheriac and 24NRM02 ConcenSus) with plans for initiation of new interlaboratory comparisons and documentary standards. Dorota is also involved in Reference Materials development (e.g. LGCQC5050) and provision of commercial measurements services, training and consultancy. She is the LGCs representative at the European and International standards development organisations, the current Chair of BSI NTI/1 ‘Nanotechnologies’ committee, and the Head of UK’s Delegation at ISO TC 229 and CEN TC 352. She also holds a role of Vice Chair of ETPN Safety and Characterisation Working Group and is a member of the CCQM Microplastics Task Group, ISO TC 24 SC4 and the UK’s subject matter expert. Dorota has led/co-lead development of documentary standards (e.g. ISO/TS 19590 on spICP-MS) and pre-normative interlaboratory comparisons (under BIPM CCQM and VAMAS TWA 35 and TWA 45).
