Figure 1. Towards the end of graduate school at the Univ. of Wisconsin, I was fortunate enough to cross paths with Dr. John Petrini and his talented Genetics lab members. Using our radiobiology-dedicated synchrotron beamline and some special software tools I had developed, I was able to help them publish three seminal papers in the field of DNA repair post-irradiation, including our 1998 paper in Science. Pictured here is one of the exciting figures from that paper, showing co-localization of DNA double-strand breaks and their associated repair after irradiation with spatially “striped” soft x-rays. (Note: John Petrini is now the Director of The Functional Genomics Initiative at Memorial Sloan-Kettering.)
