About Science

In August 2021, I embarked on my current role as a PhD Researcher in Norway at the University of Bergen. Since then, my research journey in the field of Recommender Systems has taken flight, focusing on critical issues such as fairness, diversity, biases, and responsibility within recommendations. I am actively contributing to this work as a member of the DARS research group and the MediaFutures research center, all while benefiting from the guidance of accomplished scientists and professors.

It has been brought to attention more frequently of late that RSs might have certain underlying undesired effects. Notable examples of such phenomena are Popularity Bias, Filter Bubble, and Echo Chamber. 

In my PhD project, I am currently focusing on investigating Popularity Bias and ways to evaluate and mitigate its effects.

Recommender Systems is a sub-field of AI - it is a widely used data-driven tool to help us in decision-making in various parts of our day-to-day lives. With the rapid growth of media content online, Recommender Systems have become an essential tool for supporting media users when making choices on which media content to consume.
