Research description

My research is focused on tumor microenvironment in gynecological cancers such as uterine sarcomas, ovarian and cervical cancers to understand the tissue responses such as  wound healing or inflammation created by the surgery. Furthermore, I use  3D ex vivo models by using cancer cells, tissue and immune cells to mimic tumor immune microenvironment to investigate the mechanisms behind the tissue responses which affects cancer invasion, metastasis and chemoresistance. I also focus on Bio-imaging and analysis by using several different software in manual or automated manners.
