Yesterday, our amazing İnönü University partners showcased dynamic nature of liver exchange! We had an O blood-type patient with a O blood-type donor in a planned 3-way exchange. Pre-op calculations suggested graft size was too small for a direct transplant.

Please join us for the 4-lecture mini course I will give on minimalist market design at University of StGallen this week. The course is open to all and available both in person and via zoom. See below for the registration info and the link in the next comment for the course slides.

The Turkish opposition held a massive rally today in one of Erdoğan’s most loyal strongholds. A farmer nailed it: "You can’t run a country with radish and turnip. You run it with truth, law, and justice." The turnip bit might be a coincidence — but it still lands a little too well in the U.S.

Turpunan, şalgamınan devlet idare edilmez. Adalet ilen idare edilir. Hor görülen çiftçi, yok sayılan köylü Yozgat’tan başlayıp hesap soracak! Milletin istikbalini, milletin azim ve kararı kurtaracak. Sandıktan korkan darbeciler değil, millet kazanacak!

A collusion of autocrat wannabes: According to CHP leader Özgür Özel, Erdoğan secured Trump’s tacit approval for the arrest of Turkey’s opposition leader—while Trump, in turn, has been increasingly embracing Erdoğan-style authoritarian tactics. www.bloomberg.com/news/article...?

Given the strong parallels between leadership styles of Trump and Erdogan, and the rapid deterioration of democratic institutions in the US, the same headline equally applies to Americam democracy 🙁

Before his arrest on bogus charges, opposition presidential candidate Ekrem İmamoğlu said: “No salvation alone; either all of us together, or none of us.” His words echo far beyond Turkey — a powerful call to unite against authoritarianism.

Erdogan, during his tenure as Mayor of Istanbul in 1990s famously stated “Democracy is like a train: when we reach our destination, we get off.” More than 2 million people gathered today in Istanbul (despite a 9 day holiday) to show Turkish people’s commitment to democracy.

NEW: Today in Instanbul, Turkey. A people fighting for democracy & against authoritarianism. This is how you do it! Chairman of Republican People’s Party, Özgür Özel: “Today, 2.2 million of our citizens overflowed Maltepe Square. This is just the beginning. This nation will not remain silent.” 🇹🇷

Fantastic research program offering solutions to challenges Boston Public Schools officials faced 2 decades ago when choosing between the Deferred Acceptance and Top Trading Cycles. The framework by ‪@charmelades.bsky.social & @aromeromedina.bsky.social could have served as an innovative compromise.

Unashamed self-promotion and a line of future research with the great @aromeromedina.bsky.social @uc3meconomics.bsky.social research blog uc3nomics.uc3m.es/school-choic...

In these difficult times, we find solace in the achievements of our partners in Malatya, Turkey, who performed their fifth 6-way liver exchange today 👏 Having performed 29 LE transplants in 2025 through the Banu Bedestenci Sönmez LPE system, they are on track to surpass their record of 122 in 2024 🥇

For years, I have argued that there should be a penalty for producing non-impactful research, especially in top outlets. Such a mechanism would deter the producing mediocre research, whether generated with or w/o AI. It would also help curb the undue advantage held by gatekeepers in academia.

I used AI to help write a paper and got it published. All in record time. What does this mean for research? My latest post. open.substack.com/pub/joshuaga...

Opposition from civil society is no doubt important, but it's effective, organized, *unified* political opposition that is needed to reverse the authoritarian slide. That at least is the lesson I draw from (the failures of the opposition parties in) Erdogan's Turkey. Looking at you, Democrats!

I am proud to announce that the BBS Liver Exchange System that I co-founded (along with Tayfun Sönmez and Sezai Yilmaz) just facilitated its 201st transplant. I am very proud to be helping such a brilliant and dedicated bunch of doctors and professionals. caprazkaracigernakli.inonu.edu.tr/en

Another milestone for the Banu Bedestenci Sönmez Liver Paired Exchange System: With today’s emergency 3-way exchange, it became the first system to surpass 200 transplants. In 2024, the system performed 124 transplants, 45% of all transplants. No other system performed more than 10 in a year. 1/3
