Religious public preaching (waz, as Islamic preaching is known in Bangladesh) attracts a wide array of people in Bangladesh, both online and offline. This project's goal is three-fold: 1) a methodological exploration for the correlation between popular speeches (as shown by view counts, ratings, etc.) and speech features (such as voice, linguistic features, emotional trajectory, religious sensitivity, narrative trajectory, etc.), 2) a qualitative exploration of social implications due to this pervasive phenomena online, and 3) the materiality of production, dissemination, and entrepreneurship of waz.

We analyze the generation and spread of misinformation on social media by some religious preachers, while at the same time explore technology and policy solutions to mitigate the spread of such misinformation. The particular goals also involve re-assessing existing definitions of fake news through which misinformation is categorized and analyzed in existing research.

Though repair, maintainability, and e-waste processing play an important role in re-using broken devices and creating employment in third-world countries, it rarely gets theoretical importance. Our several year-long ethnographic and design studies report the learning, collaboration, skills, craft, and safety of repairers, recyclers, and e-waste processors.

The poor waste collection, disposal, and dumping, especially in developing regions, is creating health and environmental problems. We conduct an ethnography to understand the waste ecology in Dhaka, Bangladesh, and propose a novel technology solution to support collaboration between waste pickers and residents of these communities.
