I am a computational social scientist and early career researcher whose work sits at the intersection of natural language processing, social media analysis, and computational communication science. I hold a PhD from the University of Urbino Carlo Bo, Italy (Cycle XXXVII, 2025), where I was supervised by Prof. Fabio Giglietto and co-supervised by Prof. Giovanni Boccia Artieri.

My doctoral research examined Facebook Reactions as emotional indicators of public sentiment and engagement with COVID-19 news on Indian media platforms (March 2020 – March 2022), drawing on a dataset of 68,319 Facebook posts from four major English-language outlets. The methodology integrated time-series analysis, BERTopic embedding-based topic modelling, LLM-assisted cluster labelling, and lexicon-based sentiment analysis.

Beyond my dissertation, my research agenda spans health communication, misinformation detection, platform studies, crisis communication, and psychometric scale validation. My published work has received citations tracked live below.

"Facebook Reactions" as Emotional Indicators: A Multi-Method Approach to Analyzing User Engagement with COVID-19 News on Indian Media Platforms Sawood Anwar — University of Urbino Carlo Bo, 2025 🔗 Full text — ORA Uniurb Institutional Repository

The thesis investigates how discrete Facebook Reaction types (Like, Love, Haha, Wow, Sad, Angry) function as affective engagement signals tracking shifting public sentiment across dominant news themes and pandemic phases in India. The dataset includes a focused subset of 8,622 posts covering the early pandemic phase (March 24 – April 14, 2020) alongside the full longitudinal corpus.
