Dr Javornik's research centres on digital, immersive and AI technologies, with a distinct focus on different aspects of consumer experience and well-being. She is passionate about understanding the impact of technologies, primarily at the individual level (including consumers' self-concept, financial and mental well-being, and consumption), but also in relation to wider socio-technological phenomena. Methodologically, Dr Javornik specialises in experimental studies. She also enjoys employing qualitative methods and has a growing interest in AI-enabled text analysis.

She completed her PhD and MSc at Università della Svizzera italiana in Lugano, Switzerland. During her PhD studies, she was awarded a Swiss National Science Foundation grant for prospective researchers, enabling her to spend a year-long research stay at the UCL Interaction Centre. Following this, she also undertook a six-month industrial secondment in collaboration with the London-based studio Holition, for which she obtained UCL Enterprise funding.

In 2023, she was awarded the prestigious New Investigator Grant from the ESRC for the project 'The rise of self-avatars in virtual environments and their consequences on mental well-being'.

Her work has been published in internationally recognised journals, such as the Journal of Retailing, Journal of Interactive Marketing, Journal of Business Research, Psychology & Marketing, and European Journal of Marketing, among others. She regularly presents her work at leading marketing conferences, such as EMAC, AMS and ACR, and has also presented at leading venues in human-computer interaction. Dr Javornik maintains active international research collaborations and has undertaken numerous international research visits to date.

She regularly reviews for journals and serves on the editorial review boards of the Journal of Business Research and Journal of Advertising Research. She is also frequently invited to review international grant proposals.

She is a committed PhD supervisor who enjoys working with curious PhD students, helping them develop novel ideas and research skills.

Dr Javornik has long-standing collaborations with industry through consultancy and research projects. She has delivered several workshops for international companies and executive programmes in the areas of consumer experience and digital marketing. She has also initiated and edited the University of Bristol Business School's annual blog on Digital Marketing Trends (2021–2026).
