About me

I am docent /Associate Professor in Experimental Reproductive Medicine and working as Principal Researcher in the Department of Women's and Children's Health at Karolinska Institute. I lead Experimental Research team (https://ki.se/en/kbh/experimental-research) in understanding the molecular and cellular mechanism involved in different Gynaecological conditions. It's my privilege to be part of a larger group with Clinicians,  researchers working in basic science and global reproductive health, with the focus on Translational Research in Reproductive Health/ Reproductive Medicine (https://ki.se/en/kbh/research-in-reproductive-health-reproductive-medicine-0).


Research description

Main areas of Research

  • Endometrial regeneration and endometrial receptivity aiming at managing infertility 
  • Identifying good quality embryos (GQE) for assisted reproductive treatment (ART) based on molecular profile of embryo spent media
  • Develop non-invasive, molecular based method to identify receptive endometrium and good quality of embryos for clinical use in ART 
  • Endometriosis and endometriosis associated ovarian cancer (EAOC)
  • Effect of SARS-CoV-19 on placental gene expression

We use 2D and 3D cell culture, single cell RNA sequencing, smartseq2 / smartseq3, spatial transcriptomics and bioinformatic tools to understand the molecular profile and mechanisms involved in different physiological and pathophysiological conditions in female fertility.
