Dr. Dawson received her PhD in Chemical & Biomolecular Engineering from Johns Hopkins University, then completed a postdoctoral fellowship in Radiation Oncology at Massachusetts General Hospital. Her quantitative research, intricately connected with fundamental biology, has propelled her to the role of Associate Professor in Molecular Biology, Cell Biology, and Biochemistry at Brown University. She also holds key positions as Co-Director of Graduate Studies in Biomedical Engineering and Associate Director for Cancer Research Training and Education at the Legorreta Cancer Center. Additionally, Dr. Dawson is a standing member of the Cancer Cell Biology NIH study section. Her current research investigates how aging and therapeutic interventions impact tumor progression through modifications in the tumor microenvironment. This critical work has received substantial funding from the NSF and NIH, including an NCI R01 grant focused on metabolic changes in invasive ovarian cancers.

Aging is the leading risk factor for developing deadly cancers with over 60% of newly diagnosed cancers and 70% of cancer-related deaths occurring in individuals that are 65-and-older. In the next decade, the 65-and-older population will expand as aging baby boomers turn 65. Therefore, it is a critical time to increase our understanding of the role of aging in the onset and progression of cancer and the challenges that will be associated with cancer care in an aging population. The overarching goal in the Dawson lab is to understand how senescent cells that accumulate in aging and environmentally stressed tissues contribute to tumor microenvironment remodeling, tissue stiffening and fibrosis, and cancer progression to metastatic and/or chemoresistant disease.This research is at the intersection between aging, cancer, and women’s health, since our work is solely foucsed on women’s cancers that have been historically understudied.
The Dawson lab develops in vitro models of the tumor microenvironment that can be used for quantitative analysis of senescence-associated tumor microenvironment modifications. Using high-resolution imaging, they study the dynamic structure of cells and their surrounding extracellular matrix (ECM) to see how ECM changes in the presence of senescent cells, immunomodulatory cells and proteins, and/or invasive cancer cells. In vitro studies are combined with clinical samples (patient-derived cells, ascites, or tissues), in vivo mouse studies, or human tissue array analyses to demonstrate the clinical relevance of these models. The long-term goal of this research is to understand how heterogeneity develops in the tumor and contributes to the formation of invasive and drug-resistant cells (such as polyploid giant cancer cells) in aging and environmentally stressed tumor and tissue microenvironments.
