About me & my research interests

In my research, I explore brand transgressions, focusing on when and why customers turn toxic against brands and how management can mitigate toxic customer behavior (forthcoming at AMS Review). In my job market paper, I explore rumination as the core mental process behind toxic customer behavior. More specifically, I investigate how the vengefulness of online reviews can be reduced through refocusing rumination. 

I also examine how stakeholders make sense of an emerging marketing phenomenon. I apply this interest to the phenomenon of influencer marketing, studying how social media users, brand managers, and advertising agencies make sense of and bestow legitimacy on a social media influencer. Drawing on insights from 164 in-depth interviews, we define influencer authenticity as a highly contextual attribute that is perceived differently depending on a stakeholder’s place in the market. This work, currently revising for 3rd round resubmission at the Journal of Marketing, contributes to the emerging literature on influencer marketing, and authenticity in particular.

I apply a broad set of techniques in my research, ranging from interviews, field and lab experiments, and econometric analysis of observational data.

Gallery

I was born and raised a Hungarian minority within the country of Slovakia (in Eastern Europe) and later moved to the United Kingdom for my university education. Apart from doing research, and teaching across various universities, I enjoy helping the local Hungarian community and students in particular who aim to study abroad. I also enjoy cooking, travelling, and playing golf.

This gallery presents moments I captured in my journey across Europe, and conferences in the US and Asia.

I am pictured here with the major and deputy mayor of my home town, Šamorín (called Somorja in Hungarian) in the south of Slovakia. As a proud member of the local Hungarian minority, I was happy to share my experiences studying abroad, and discuss how I can help and represent the local Hungarian community further.

I finished a local Hungarian high school in Slovakia. As a member of the Hungarian minority in Slovakia, I was proud to go back to my high school and talk more about my PhD journey. I am pictured here with the vice-dean of the school, and my former teachers who inspired and supported me to further my studies abroad.
