Dr. Kozai has been a postdoctoral trainee since Jan. 2023. Published in the journal Placenta, this article details a technique to quantify fetal placental capillaries using immunohistochemsitry staining and a freely-available digital pixel count algorithm. This method provides a continuous-scale metric of placental health that can complement traditional dichotomous histopathological techniques.
