Research Statement

My broad research interests primarily focus on developing novel medical technologies that will enable clinicians to better detect, diagnose, stage, treat, and monitor patients. More narrowly, the technologies I am interested in developing take advantage of the inherent electrical and mechanical properties contrast between different tissue types and pathologies. I am interested in both translatable research (getting these new technologies into the hands of clinicians) and the more basic science and engineering aspects of better understanding the biology influencing a tissue’s electrical behavior, and developing techniques to accurately gauge these properties. I am actively applying these technologies to a variety of clinical conditions. I describe my research efforts as three separate activities that are, by design, coupled in order to enhance development of bench-to-bedside technologies. First, I am actively exploring and quantifying the available electrical property contrast in diseased tissue and developing theoretical approaches and testing hypotheses that explain the underlying biophysical mechanisms responsible for this contrast. Second, I am actively developing bioinstrumentation able to accurately gauge and image these properties. Third, I am leveraging 1) the knowledge gained from understanding contrast levels and mechanisms and 2) the instrumentation designed and constructed to integrate these technologies into the clinical environment. These three primary areas of research all feed into my current overarching goal of developing clinical applications for bioelectromagnetics.
