Big congratulations to Dr. Luigi Arminio. Yesterday he defended his thesis on Polarisation in an Evolving Social Media Landscape: Multimodal Insights from the Climate Debate.

Supervisor: Luca Rossi
Committee: Luca Aiello, Cornelius Puschmann, Cindy Shen

We are extremely happy and proud of Luigi’s research dealing with the crucial issue of online polarisation and producing both substantial contribution as well as methodological advancements.

Luigi’s work is built on 6 papers and investigated both textual and visual data. On the textual side he showed how opposite groups in a polarised debate are recognisable by specific socio-linguistic feature that we can detect computationally. On the visual side he contributed to the development of a research pipeline that leverages Visual Large Language Models to produce semantic clustering of visual content. This was then used to study the ongoing visual narratives surrounding the climate debate.

On March 1st Luigi will start a research position at Roskilde University in the context of the Algorithms, Data & Democracy project but we know that our collaboration isn’t over.
