About me

Sophie Petropoulos, PhD has merged her expertise in the fields of physiology, developmental biology, epigenetics and single-cell genomics to gain an understanding of early preimplantation development.  Her research interests focus on how early events such as parental or environmental exposures can result in fetal reprogramming, ultimately leading to the onset of disease or disorder later in life.   Dr. Petropoulos completed her PhD in the Department of Physiology, University of Toronto and then joined the Department of Pharmacology and Therapeutics at McGill University where she specialized in epigenetics.  She then moved to the Karolinska Institutet, Department of Clinical Science, Intervention and Technology and the Ludwig Cancer Research Institute where her studies investigated human preimplantation development using single-cell RNA-sequencing.

Research description

Embryo, Development, Epigenome, Single-Cell OMICs, Artificial Reproduction, Fetal Programming

The Petropoulos lab aims to:

1) Investigate how the early ex vivo environment, as occuring during Artificial Reproduction, impacts the developmental trajectory of the embryo and placenta- potentially programming the developing fetus for disease and disorder later in life.  

2) Investigate signaling occuring between the polar side of the human embryo and endometrium to shed light on underlying mechanisms of implantation.  We hope to ultimately establish predictive biomarkers associated with successful implantation.
