Hi all, RIPE 91 will take place 20 -- 24 October in Bucharest. We are seeking presentations for the MAT WG session, scheduled on Tuesday, 21 October! Interesting topics include (but are not limited to): * Measurement research which has an operational impact * Operational initiatives that could inspire new research directions * Projects focused on network data collection * Tools for network data analysis and visualization * Innovative measurement techniques and proposals Starting from RIPE 91, both plenary and working group proposals can be submitted through the same system, Pretalx: https://pretalx.ripe.net/ripe91/ The Pretalx submission form will ask you for various details. Please select the MAT track, and include a title & abstract (these will eventually become public). For our evaluation, please include the following in your proposal: * an outline of your presentation (under 'notes') or provide a draft slide deck * the slot duration you'd like; we tend towards 15-20 minutes including Q&A, but please specify * whether you intend to present in person or online The deadline for MAT WG proposals is 15 September 2025. We will make our selections and post our agenda soon after. If you have any questions, please contact us at mat-wg-chairs [at] ripe.net. Thanks! - Nina, Massimo, Stephen as WG chairs
