In my research, I explore the cooperation between different stakeholders in influencer marketing, with the goal of better understanding how influencers can be effectively leveraged (e.g., in terms of their authenticity; revising for 3rd round resubmission at the Journal of Marketing).

 

I also study transgressions, focusing on when and why customers turn toxic against brands and how managers can mitigate this behavior. I investigate rumination as a core mental process behind toxic behaviour, and in my job market paper, study how the vengefulness of negative reviews can be reduced through refocusing rumination (invited for revision at the Journal of Marketing).

In my research, I apply a broad set of techniques, including interviews, field and lab experiments, and econometric analysis on observational data. I thus consider myself a multi-method researcher for whom questions precede methods.

I am a passionate educator who believes in the power of active learning and student-centred approaches that prioritize collaborative problem-solving, class discussions, and real-world application of concepts.

 

So far, I have been teaching various modules across marketing strategy, analytics, and consumer behavior––and at all levels, namely to under- and postgraduates (at Imperial College Business School, ESCP London, and in the Boston University’s Study Abroad Program) as well as to MBAs and EMBAs (Imperial College Business School). The opportunity to teach students across three different schools has enabled me to listen to and appreciate the varied perspectives and experiences students have, while striving for inclusion in my classroom, and beyond.

 

At Imperial College London, I was fortunate enough to have been nominated for the Teaching Excellence Award in two consecutive years (2022, 2023).
