I am a research specialist at Kaisa Lehti's group (MTC). My main research interests are the biophysical, biochemical, and cellular aspects of the tumour microenvironmnet and their impact on tumourigenesis and tumour development. A second focus of my research is the development of 3D in vitro culture methods using Biomaterials to mimic and study the tumour microenvironment.
Sarcomas are a very diverse group of malignancies accounting for about 1% of adult and 15% of childhood cancers. Sarcomas arise from connective tissues and are typically rich in structural extracellular matrix (ECM) proteins such as fibrillar collagens, however specific sarcoma subtypes such as rhabdomyosarcoma and leiomyosarcoma are exceptions. With the final goal of improving patient treatment, we are investigating the impact of the tumour microenvironment, with a biomechanical and ECM focus, on sarcomagenesis and tumour progression. We are currently working on two main sarcoma projects:
- Impact of cell- and ECM-induced mechanical confinement on rhabdomyosarcoma tumorigenesis and tumour progression.
- Dysregulation of fibrillar collagen turnover and mechanosensing in leiomyosarcoma.
These studies involve an in-depth tissue characterisation combining multi-omics technologies with biomechanical and image analysis techniques. Moreover, we develop biomaterial-based 3D culture systems to mimic clinically relevant cellular and ECM tissue features to functionally assess the mechanisms of action of potential novel biomarkers and therapeutic targets.

Ovarian Cancer Projects
In high grade serous ovarian cancer (HGSC), cancer cells originating in the ovary/fallopian tube disseminate throughout the peritoneum and invade the fatty tissue of the omentum. This process involves cell migration through adipose tissue and considerable remodelling of the tumour microenvironment (TME). With disease progression, the initially adipocyte-rich tissue is increasingly replaced by a fibrotic tissue with high extracellular matrix (ECM) and cancer associated fibroblast (CAF) content, leading to profound changes in cellular composition, tissue architecture, and mechanics. We aim to understand how HGSC cells invade and remodel the omentum, and how the evolving features of the TME regulate therapy response. To answer these questions, we combine the analysis of patient-derived tissue, ex vivo cultures and co-cultures, and the development of novel hydrogel-based artificial tissues.
