Epidemic dreams: dreaming about health during the COVID-19 pandemic
Published in The Royal Society Open Science, 2021
TL;DR We show that COVID dreams feature both common and specific symptom mentions, when compared to waking life COVID experiences. E.g., expressions in waking life described realistic symptoms (e.g. nasal pain, SARS, H1N1); while those in dreaming life reflected either conditions unrelated to the virus (e.g. maggots, deformities, snake bites), or conditions of surreal nature (e.g. teeth falling out, body crumbling into sand).

The role of the big geographic sort in online news circulation among US Reddit users
Published in Nature Scientific Reports 13 (1), 6711, 2023
TL;DR Our study challenges the traditional understanding of online news circulation, demonstrating that it is not just individual characteristics and social media algorithms at play, but also the influence of localized offline self-segregation (the Big Sort) in the US. The study underscores that the diffusion of news, especially misinformation, is significantly influenced by state-level personality, cultural factors, and education levels, highlighting the geographical nature of online interactions.

Insider stories: analyzing internal sustainability efforts of major US companies from online reviews
Published in Nature Humanities and Social Sciences Communications 10 (1), 1-9, 2023
TL;DR While many modern corporations proclaim their commitment to Corporate Social Responsibility (CSR), allegations of “greenwashing” are not uncommon. This study employs Glassdoor reviews to quantify an underexplored facet of CSR – internal sustainability. This broad term encapsulates various policies targeted towards internal stakeholders, such as advocating for a balanced work-life ecosystem, prioritizing gender equality and diversity, and fostering a harassment-free work environment.

Computational Social Science from Space
Published:
In this tutorial, together with Prof. Ingmar Weber, we introduced satellite imagery as a fresh data source for social scientists. We strived to bridge the gap between Earth Observation and social media data analysis, fostering interdisciplinary cooperation. We also tackled the need for responsible data use standards. Attendees explored the use of satellite data and engaged in interactive discussions. We also provided hands-on training in Google Earth Engine, demonstrating the long-lasting effects of racially biased housing policies, visible from space. Tutorial Website More Information
