Research Focus

Research Overview: The Duvall Advanced Therapeutics Laboratory (ATL) specializes in design and application of smart polymer-based technologies for: (1) intracellular delivery of biological drugs such as peptides and nucleic acids, (2) proximity-activated targeting of drugs to sites of inflammation and matrix remodeling, and (3) long-term, “on-demand” drug release from localized depots. These delivery systems are designed to improve the therapeutic benefit and safety of existing drugs and/or to serve as enabling technologies for manipulation of intracellular targets currently considered to be “undruggable”. To achieve optimal, finely-tuned properties for these varied biomedical applications, we develop polymers that respond to one or more environmental stimuli including pH, matrix metalloproteinases, reactive oxygen species, and temperature. The disease applications of our polymeric biomaterial and drug delivery technologies are broad, including increasing longevity and function of transplanted vascular grafts and cell-based therapies, promoting healing of chronic skin wounds, and developing improved breast cancer drugs.

Research Environment: The Duvall lab moved in summer 2017 to the new Engineering and Science Building (ESB) where we are co-localized with other BME faculty working in biomaterials, drug delivery, regenerative medicine, molecular and cellular sensing, immunoengineering, and mechanobiology. This collaborative research environment will contain all of the multidisciplinary expertise and equipment necessary to carry out cutting edge research across the full spectrum of synthesis, characterization, and biological testing of bio- and nano-materials.
