Dr Sion Coulman is a Reader at the Cardiff School of Pharmacy and Pharmaceutical Sciences. He has worked with microneedle-based devices since 2002, exploring their potential as a minimally invasive method for trans- and intra-dermal delivery of both novel and established active pharmaceutical ingredients, including biologics. He has been involved in the design and characterisation of a range of microneedle-based delivery systems and has a particular interest in developing models and methods to characterise their performance and understand their interaction with the skin and the user. He is currently part of the Vax-Hub global consortium and is a co-Chair (with PATH) of the Microneedle Array Patch - Regulatory Working Group (MAP-RWG), which aims to inform the regulatory science of microneedle array patches in an effort to expedite clinical translation of the technology.
