Associate Professor, University of Copenhagen, Niels Bohr International Academy, Denmark
Niels Emil J. Bjerrum-Bohr is a great-grandchild of Niels Bohr and an Associate Professor at the Niels Bohr Institute in Copenhagen. He moved to Copenhagen from Institute for Advanced Study (Princeton, USA) for a Knud Højgaard Assistant Professorship at the Niels Bohr International Academy in 2009 and has since established his research in theoretical physics with grants from both Lundbeck and Carlsberg Foundations as well as the Independent Research Fund Denmark.
His research focuses on quantum amplitudes in QCD and gravity – an exciting playground for high-energy theory, phenomenology, and in the aftermath of the direct observation of binary black hole mergers, also gravitational dynamics.
Dear Prof. Bjerrum-Bohr: Congratulations on your selection as a speaker. In your talk or in other talks of your colleagues in this IYBSSD2022, will you or others include the increasing effects (observed or predicted) of radiation on the human population or selected parts of it. This includes both man-made and natural sources of radiation, both increasing. Also included are terrestrial background radiation exposure levels as from 5G communications (from all devices, not just smart phones, and 6G in the next decade), in medical diagnosis and therapy, and in space travel (ongoing or planned), for example. The question also pertains to materials, parts and structures used by man for engineering and construction purposes. “Radiation” means here all types, such as electromagnetic, acoustic, elastodynamic and nuclear (and, to be complete, even gravitational!). While the energy levels for the preceding are typically low (except for cosmic rays) as compared to those you encounter in your QCD research, it makes sense to include the entire energy spectrum, partly as low-energy and high-energy effects can occur simultaneously, as in NMR, the Moessbauer effect, and nonlinear interactions of radiation with matte5r. This question pertains to basic science, as some of the models for radiation effects on matter are only approximately true, and as researchers become more interested in explaining interactions observed at the quantum level such as at nanoscopic size scales including those of primary, secondary and even tertiary structural features of large macromolecules in living tissue such as DNA and RNA, and many proteins. Thank you. Thanks, too, for your grand-dad Prof. Niels Bohr whose atomic physics I encountered in college before studying QED in graduate school (as of the hydrogen atom) on the way to earning a Ph.D. in physics awarded in 1974.
