I'm incredibly honored to be one of the inaugural winners of the Ctrl-Z award. The sequence of events preceding and following this retraction were harrowing (and are honestly still stressful), but I hope this will be an opportunity for more open dialogue about mistakes + self-retraction in science.

From tiki-taka to "attacki-taka" (sorryy, cheesy) was the only way I could describe Spain's play under Luis de la Fuente. That, plus some Messi magic... great preview article for Sunday's ESP 🇪🇸 - 🇦🇷 ARG matchup, by @cesareor.bsky.social @nuglobalnews.bsky.social news.northeastern.edu/2026/07/16/s...

We've been doing a lot of stories with @nuglobalnews.bsky.social the last month, but this was one of the more fun/silly/interesting ones to work on: What, in the data, makes a soccer match "exciting"? (less soulless than it sounds, I promise!) news.northeastern.edu/2026/07/08/m...

What makes a soccer match exciting? There’s data for that
Most exciting World Cup matches get ranked by a new algorithm from Northeastern researcher Brennan Klein, based on stakes, drama and payoff.
