Natalie Geyer

I am a cancer biologist at the Division of Surgery and Oncology (CLINTEC, Karolinska Institutet), where my research in the Cancer Cell Invasion Lab (group leader: Marco Gerling) centres on understanding microenvironmental control of tumor invasion. 

Tumors reshape their surrounding cellular niches forming a growth-promoting microenvironment. However, so far, little is known about the role of epithelial host cells in this context, especially in the metastatic setting. Using liver metastasis resections from Karolinska University Hospital in Huddinge together with murine disease models, I study cellular communication mechanisms that drive tumor-host interactions at the invasive edge of metastases. Our work connects spatially resolved and mechanistic approaches to clinical questions, and is rooted in close collaboration across disciplines.

With a passion for lecturing and science communication, I engage in various teaching activities. 

Lecturer
- Lecture on "Transfection and reporter genes" (Bachelor in Biomedicine, course "Genetics, Genomics and Functional Genomics", Karolinska Institutet, 2026)
- Lecture on cancer biology for high school students (Ung Vetenskapssort, Biology camp, 2026)
- Lecture on "Pancreatic cancer mouse models" (Ph.D. course "Incurable Cancers", Karolinska Institutet, 2022)

Supervision & other activities
