Dr Michelle Norris shares how her project, ‘BREASTech’, is working to better understand how software and technology can impact the physical activity levels of breast cancer patients and survivors. She also discusses how her training as an ALECS Marie Curie COFUND fellow is helping her to share the impact of her research with a wider audience. This work was supported, in part, by Science Foundation Ireland grant 13/RC/2094 and co-funded under the European Regional Development Fund through the Southern & Eastern Regional Operational Programme to Lero - the Irish Software Research Centre (www.lero.ie) and has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 754489.
