About me

  • I currently hold two positions at the Karolinska Institute (KI). I am a team leader in the larger group of Olli Kallioniemi at the department of
    Oncology-Pathology. I am a group leader at SciLifeLab, and scientific director at Chemical Biology Consortium Sweden (CBCS) KI node.

Research

  • Our ultimate goal is to promote the move away from one-size-fits-all therapies to improve patient outcome through treatment stratification and tailoring. Despite advances in precision medicine diagnostics, there are still major opportunities to improve individualized patient care throughout the entire health care value chain, spanning from preclinical studies in drug discovery through to the design of precision diagnostics. Research in my team focuses on challenges central to these fields, developing technologies and disease models that enable direct measurement of patient response to treatment /ex vivo /and investigation of the molecular determinants of drug response. Such methods and model systems are critical to improve the study of disease biology, identify and validate new drug targets, correctly prioritize drug candidates for clinical trials, uncover potential biomarkers for future patient stratification and have even recently been used successfully as diagnostics to match patients to effective treatments. Our translational research group and surrounding team of clinicians and experts has two major themes as described below united by the main goal of investigating drug response and biomarkers in primary patient cells and other near-patient models of disease.

Teaching

  • I co-organize a doctoral course in cancer drug discovery.

    Despite initial responses to chemotherapy, over 70% of ovarian cancer patients experience relapse, largely driven by cellular plasticity—the ability of cancer cells to transition between distinct states to evade therapy, adapt to new microenvironments, and promote metastasis. Current therapeutic strategies fail to account for the dynamic nature of cancer plasticity in individual patients. A major challenge in translating plasticity-targeting strategies into clinical practice is the absence of: 1) systematic, patient-specific plasticity maps across ovarian cancer subtypes and microenvironments, 2) scoring systems to guide plasticity-targeting therapy allocation and 3) effective treatments and combinations.This project pioneers an integrative, patient-specific approach that combines single-cell plasticity mapping, high-content imaging, and functional drug screening to uncover targetable vulnerabilities in ovarian cancer. By defining patient-specific plasticity signatures and their therapeutic susceptibilities, this research will provide a blueprint for integrating plasticity-targeting strategies into precision oncology. Ultimately, this work will generate clinically actionable insights, paving the way for personalized interventions that disrupt plasticity-driven resistance and improve survival outcomes in ovarian cancer.

    Chemical health risk assessment has failed to protect female fertility. Women are exposed to mixtures of synthetic chemicals linked to reduced ovarian function, lower embryo quality, and decreased fertility. Our previous FORMAS studies revealed new molecular targets in ovarian and endometrial cells exposed to chemicals in vitro, highlighting mechanisms related to metabolism, energy balance, and structural cellular biology, expanding the scope of reproductive toxicity beyond classical endocrine disruption. In HERTOX, we will develop these endpoints into high-throughput screening (HTS) assays using platforms originally designed for cancer drug testing. Human ovarian and endometrial cells will be cultured in 2D and 3D in 384-well formats, exposed to a customized library of up to 5 000 chemicals, and analyzed with multiplexed fluorescence imaging. Selected hits will undergo further testing for concentration-response properties, combinatorial toxicity, and validation through metabolomic and transcriptomic analyses. Structure-activity relationships will be analyzed, and the curated chemical library will be made available to researchers. Finally, selected exposures will be validated for their association with adverse outcomes in women using ovarian tissue cultures, a human stem cell-based embryo attachment model, and patient samples. HERTOX ambition is to deliver HTS systems predictive of reproductive toxicity in women.
