Arwyn is very active in public engagement of science. He has gained funding from both the Wellcome Trust and EPSRC to set up large public engagement activities - see below. He regularly contributes to BBC/S4C TV and Radio Cymru news programmes, is also actively engaged in discussing other aspects of science on TV and radio and also visits local schools and colleges to showcase science.
2014 The Science of Pollination
In 2014 Arwyn in conjunction with the National Eisteddfod of Wales organised a large large science exhibition in the Science and Technology Pavilion at the National Eisteddfod of Wales in Llanelli. He teamed up with Aberystwyth, Swansea, Cardiff Metropolitan and Bangor Universities, the International Bee Keepers Association and the National Botanic Garden of Wales to raise awareness of the importance of pollination in conservation, agriculture and medical sciences.
The School of Pharmacy and Pharmaceutical Sciences exhibit was staffed by Arwyn and a team of junior scientists including Pharmacy undergraduate students. This exhibit focused on the science of honey and the detective work underway at Professor Les Baillie's laboratory at the School of Pharmacy and Pharmaceutical Sciences to identify antibacterial properties of honey collected from different parts of Wales. Over the course of the Eisteddfod week 25 samples of Welsh honey were handed in for Arwyn to take to the School of Pharmacy for analysis. The very young children loved making bees out of clay and also extremely popular was an opportunity for children and adults to extract pollen from Welsh honey and see amazing pollen shapes under the microscope.
Dr Wheldon-Williams from the National Eisteddfod said 'This was the first time that so many Universities in Wales have got together under one roof to address a common issue, it was a fantastic achievement and a great project". Over the course of eight days 18,000+ people attended the Science and Technology Pavilion to engage and interact with science and the scientists doing the work.
2010-2011 Tissue Engineering for Human Healing
In 2010 and 2011 he lead a Public Engagement project sponsored by the EPSRC to highlight the multidisciplinary science involved in, and potential of, tissue engineering. This £55K Partnership for Public engagement award "Tissue Engineering for Human Healing" was obtained with Dr Bob Steadman (School of Medicine) and Dr Pete Griffiths (School of Chemistry) and involved setting up tissue engineering exhibits at various locations and activities in Wales. The exhibit was launched at the 2010 National Eisteddfod of Wales in Ebbw Vale. There were a host of interactive and educational material on display at the Eisteddfod Science Pavilion throughout the week. This included a life size operations game and daily maggot races. A new Stem Cell Puzzle went on display for the next major showing of this exhibit at the National Eisteddfod of Wales in Wrecsam. The Stem Cell puzzle is now part of the Public Engagement activities at Techniquest Science Discovery Centre where it is also being used for training in Public Engagement as an exemplar of making research accessible and relevant to the public.
