R and AI - so many options. What works for you?

Z2.01 - Mediadrôme

Over the last 12 months or so, ways of getting LLMs to help you write R code have multiplied. The Ellmer package is one solution. Then Posit tested their Databot, and later the Posit Assistant. There's also GitHub CoPilot. So what have you tried? What has worked? What have you learned? Are you happy using AI in R code? Are you still waiting to take the plunge? Come to this roundtable session to learn from each other's experiences in this rapidly developing field.

Coordinators of cross-border investigations are welcome to join a session with Coordinators Without Borders, a monthly meet-up for coordinators of cross-border investigations. This will be a social gathering for members of the group and those interested in joining. All are invited to revisit the group’s collaborative attempt to craft the “perfect” memorandum of understanding. This document is an essential part of any cross-border investigation, marking an agreement between journalists over the many elements of the collaboration, including the responsibilities of the coordinator.

Investigative journalism on health: networking roundtable

Saturday May 30, 2026 5:15pm - 6:30pm CEST

Z2.01 - Mediadrôme

Health is one of the most cross-border beats there is. Pharmaceutical companies, regulators, clinical trials, food and tobacco lobbying, environmental hazards, patient harm – none of it stops at borders. Whether you've been on the health beat for years, have just started chasing your first lead, or are simply drawn to the topic and wondering where to begin, come and meet others working in the same space. The goal is to leave the session knowing a few people you'd genuinely want to team up with on the next investigation.
