Hi, my name is Isaac Martinez. I am a PhD student in Economics at the LSE, and I wanted to share something personal. On July 6, 2025, I suffered a stroke while I was finishing my PhD. It was completely unexpected and changed my life. #EconTwitter #EconJobMarket

Various assignment mechanisms are used by universities to pair students with professors.
When learning is subject to student-professor match effects, have you ever thought about the role these mechanisms play in shaping learning outcomes?
