The world health organization has identified air pollution and climate change as one of the top ten threats to global health in 2019. The incidence of life-threatening diseases is growing every year and exposure to environmental hazards has been linked to the causation of many of these diseases including cancer, heart disease, and autoimmune diseases such as type 1 diabetes. Biomaterials have revolutionized strategies to combat these life threatening diseases; from tools to better understand disease development to tissue engineering strategies and drug delivery platforms. Biomaterial scaffolds are highly tailorable platforms that can be engineered to interact with existing tissue, mimic native tissue including cellular interactions with extracellular matrix molecules, and even alter cellular behavior.
The main goal of my research is to develop biomaterial scaffolds to investigate cellular interactions with their environment and to harness this information to develop therapies for life threatening diseases. My research primarily focuses on type 1 diabetes (T1D), which is characterized by the progressive destruction of the insulin producing β-cells in the pancreatic islets of Langerhans by activated immune cells. The goals of my research are to 1) understand the role of extracellular matrix interactions in cellular death and dysfunction during the onset and progression of T1D, 2) further the understanding of pancreatic islet dysfunction and death mechanisms during the pathogenesis of T1D, and 3) develop therapies which preserve islet function and mass after the onset of disease. This research combines novel biomimetic scaffold design with advanced live-cell imaging techniques to provide quantitative insight into pancreatic islet function and disease development. The discoveries that we make will ultimately help to improve therapies for patients with T1D.
