Andrzej Galbarczyk


I have been working with the team since 2002. During my PhD studies I investigated polymorphism of cytochrome genes and levels of estradiol and progesterone in women. I am also interested in menopause and proposed a hypothesis that age at birth of a first daughter is one of predictors of menopausal age. Currently I am working on a project “The impact of tattoos on assessments of male attractiveness”.
