I am Shohei Kuraoka, Assistant professor in the Department of Pediatric Medicine. I completed my MD in 2008, and started my PhD in 2016 in Kidney Development, working with Prof. Ryuichi Nishinakamura at Kumamoto University, Japan. I’m currently working as a pediatric nephrologist in a hospital and continuing basic research in Kidney Development, having completing my PhD study in March 2020. My main interests are kidney development and disease modeling. I have worked in modeling polycystic kidney disease from the iPSC-derived kidney organoid, and my work has been published in J Am Soc Nephol 2020. From 2020, I belong to the Japan Environment and Children’s Study (JECS), a large-scale nationwide birth cohort study. In JECS, my new interest is "Nutrition and Child health". So, my current work is my first research using JECS data.
