Professional Statement
Throughout my research I have focused on how DNA is able to be an active participant in its transactions. DNA structure, particularly the structure of supercoiled DNA, is much more variable and dynamic than many people realize. This insight has allowed me to contribute to a better understanding of protein-DNA interactions and DNA itself. In the process, I have also developed unique DNA tools that are proving to be extremely useful, not only for basic research, but also clinical applications. I have developed a patented protocol to generate milligram quantities of supercoiled minicircle DNA, as small as 250 bp. Using these DNA minicircles, I precisely determine the supercoiling dependence of topoisomerase binding and additionally elucidate the mechanism through which DNA topoisomerases recognize their supercoiled DNA substrate and determine where to act. These minicircles also provide a unique insight into the structure of supercoiled DNA, including previously unappreciated differences between overwound and underwound DNA. Throughout my career I have collaborated with researchers from many disciplines including biochemistry, biophysics, physics, mathematics, structural biology, and medicine.
