Jiajin Yan

I am a medical statistician at the Karolinska Institutet, with a BM from Xiamen University and an MS in Global Health from KI. My work includes register-based epidemiology, survival analysis, and causal inference, with long-standing interests in causation theory, methodological rigor, and bridging clinical medicine with statistical practice. A particular focus is the epistemic foundations of causal inference in observational research: what it means to say that an exposure causes an outcome, and how far our methods can take us toward that claim. I have contributed to 18+ publications in journals including European Heart Journal and Gastroenterology.
