About me


I am Assistant Professor in Marketing and Strategy at Cardiff Business School, where my research focuses on the psychological and social dynamics of misinformation, digital trust, and social influence.

My work examines how exposure to misleading or low-quality information shapes people’s mindsets, decision-making, and relationships with brands, institutions, and technologies. A central theme of my research is understanding when and why misinformation activates distrust, how this spills over into unrelated domains (such as consumption), and how interventions—such as credibility cues, media literacy tools, and platform design—can help people navigate complex information environments more effectively.

Methodologically, I primarily use experimental designs, often complemented by mixed methods and secondary data, to study both the bright and dark sides of digital communication. My research also engages with emerging issues around AI-mediated information, influencer communication, and public value.

My work has been published in leading international journals, including Psychology & Marketing, Journal of Business Research, Journal of Advertising Research, and Journal of Public Policy & Marketing, among others. I also serve as Social Media Editor for Psychology & Marketing and as a member of editorial review boards for several journals in marketing and consumer research. I also serve as affiliate to the International Panel on the Information Environment.

Before joining Cardiff, I completed my PhD at the University of Portsmouth and have held visiting research positions, including at Columbia Business School. Beyond academia, I regularly engage in doctoral training, public scholarship, and interdisciplinary collaborations aimed at addressing the societal consequences of misinformation.

Research

My research examines the psychological and behavioural dynamics of misinformation spreading and its consequences for consumers, brands, and digital trust. I focus on how both direct misinformation—content that explicitly targets brands, products, or messages—and indirect misinformation—broader misleading content in the information ecosystem that does not explicitly mention a focal object—shape consumer beliefs, attitudes, and marketplace relationships. This work has shown that misinformation can erode trust not only by misrepresenting specific targets but also by activating mistrust mindsets that spill over into unrelated decision contexts, influencing how people evaluate products, institutions, and marketing stimuli.

Another strand of my research explores how social media formats and source cues influence misinformation sharing and belief, and how information legitimacy can be enhanced or undermined through network and messaging features. I also investigate the dark side of social and influencer marketing, including how misleading or deceptively framed digital content affects engagement, perceptions, and marketplace outcomes.

My work contributes to theory by differentiating mechanisms of misinformation impact—from explicit brand attacks to diffuse, ecosystem-wide effects—and to practice by informing strategies for trust restoration and credible communication in digital environments.
