Bradford G. Orr is the Arthur F. Thurnau Professor of Physics in the College of Literature, Science, and the Arts at the University of Michigan , where he also serves as Associate Vice President for Research (Science & Engineering) . His group uses scanning probe microscopies and molecular-beam epitaxy to explore surface-controlled phenomena in nanoscale semiconductors and, in parallel, engineers multifunctional dendrimer nanoparticles for targeted cancer therapy. Education Ph.D. Physics, University of Minnesota, 1985 B.S. Physics, University of Minnesota, 1980 Research Interests Professor Orr’s work sits at the intersection of condensed-matter physics , surface science , and nanomedicine . He investigates: Surface & Interface Physics: atomically-resolved structures of Si/SiO₂ interfaces, self-assembled monolayers on Au, and composition-modulated compound-semiconductor superlattices. Nanobiotechnology: functional poly(amidoamine) dendrimers as drug-delivery vehicles, lipid-membrane interactions, and real-time AFM imaging of cancer-cell apoptosis. Cross-disciplinary Collaboration: active partnerships with Chemistry, Materials Science, the Medical School, and the Center for Biologic Nanotechnology. Scientific Awards Arthur F. Thurnau Professorship (endowed chair) Grants & Advising While specific grant numbers are not listed, his sustained publication output from 1994 through 2021, coupled with leadership roles in university-wide research administration, indicates continuous federal and institutional funding. The group trains a steady stream of graduate students and postdoctoral researchers, though individual advisee names are not provided in the text. Labs & Facilities Research is conducted in the Randall Lab and Homer A. Neal Lab within the Department of Physics, 450 Church Street, Ann Arbor, MI, and leverages shared instrumentation across the University of Michigan nanofabrication and biological imaging cores.
