Sorcha Newby is a psychology lecturer and PhD researcher, specialising in the psychological impact of social media on children’s wellbeing.
Her research focusses on how emotional engagement with platforms such as Instagram, Snapchat, and TikTok influences anxiety, cognitive development, and sleep quality in pre-adolescents.
She is also a mother of two young children, which brings a unique personal perspective to her work on digital wellbeing and the everyday realities of raising children in a hyperconnected world.
With an undergraduate degree in psychology already under her belt, Sorcha Newby is currently working on a PhD from De Montfort University on social media and sleep quality, looking at how different types of social media-based social anxiety predict sleep quality in young children.
As well as her own personal experience bringing up two young children, Sorcha’s career has seen her work as a voluntary child educator, educating primary school children about online safety, focusing on topics like phishing, cyberbullying, grooming, and digital footprints.
Whilst studying, she worked as a research assistant and psychology brand ambassador. She has been an assistant lecturer at Arden University since 2022, and continues to carry out research and contribute to papers on the intersection of digital technology and mental health.
Through her research, she has found out that “the platforms we use daily are not designed with wellbeing in mind – but that doesn’t mean we’re powerless”. Sorcha bridges the gap between research and real-world solutions, helping parents, schools, and organisations to understand the hidden psychological effects of digital consumption and how to effectively navigate them.

As a speaker, Sorcha brings clarity and expertise to the complex issues at the intersection of technology, social media, and mental health. She speaks at schools, conferences, and corporate events, providing insights on how to protect children’s mental health in a digital world; how short-form content is requiring attention spans; the impact of passive scrolling and social media addiction; and building digital resilience.
