Over the past several decades, synthetic materials have contributed dramatically to new prophylactic and therapeutic treatments for a range of illness and disease, but drug delivery – the time, concentration, location, and specificity with which biological cargo is delivered – continues to be a major obstacle for medicine. My research interests have focused on designing and exploiting synthetic materials to achieve increased levels of control over the delivery of biological cargo. During this poster session I will highlight examples from my graduate and postdoctoral research which demonstrate the utility of synthetic biomaterials for enhancing the delivery of drugs, proteins, and nucleic acids in vitro and in vivo, and more recently, in the context of translational research focused on vaccination and immunotherapy. Building on this past work, I will describe my plans to nucleate a distinct, independent research program at the interface of immunology and materials engineering.

I completed doctoral studies at the University of Wisconsin – Madison under the guidance of Professor David Lynn in the department of Chemical and Biological Engineering. One major research area centered on development of degradable multilayered films that permit spatial or temporal control over the delivery of DNA and proteins from the surfaces of biomedical devices such as intravascular stents. In collaboration with the Abbott research group at UW, I initiated a parallel project aimed at exploiting the properties of a redox-active ferrocene-containing lipid to reversibly control DNA interactions using chemical and electrochemical cues. In October 2009 I accepted a postdoctoral fellowship from the Ragon Institute of MGH, MIT, and Harvard, initiating postdoctoral research with Professor Darrell Irvine at MIT. My postdoctoral work focuses on enhancing vaccination by exploiting the properties of biomaterials to increase the persistence of vaccine components in lymph nodes – the key site of immune response generation – and to engineer specific immunological profiles by controlled release of small molecules (immunomodulators) known to bias immune response.

A central theme of my research is application of basic science to develop new technologies, which is illustrated by my past projects in drug delivery that have generated 4 patent filings and 22 peer-reviewed publications. Immunology is an area flush with opportunities to apply biomaterials in the study of basic questions and to develop new strategies for improving human health. My expertise in biomaterials design, immunology, and vaccinology uniquely positions me to capitalize on these opportunities. The overarching goal of my research lab will be to exploit biomaterials to generate immune responses with specific, tunable characteristics. This concept has two research thrusts: 1) basic investigations aimed at understanding interactions between synthetic materials and key immune cells, and 2) development of biomaterial vaccines to combat infectious diseases and autoimmune disorders.
