Magdalena Klimek


I am a PhD Candidate in the Department of Environmental Health, Jagiellonian University Medical College. Since 2007 I work with Grazyna Jasienska at the Mogielica Human Ecology Study Site in southern Poland.
I am involved in many national and international research projects, also as
a Principal Investigator.

I am interested in developmental origins of adult reproductive history and health. In my work I use three different markers: 2D:4D digit ratio, finger ridge counts and level of facial fluctuating asymmetry.
