DESCRIPTION:Modern first-principles (or “ab initio”) many-body simulations 
 make it possible to compute the structure of atomic nuclei from scratch\, s
 tarting from effective field theories of quantum chomodynamics. Recent deve
 lopments have extended the reach of these simulations to the heaviest stabl
 e isotopes\, to higher precision\, and to new applications including many s
 tudies of fundamental interactions in nuclei. Particularly key in these app
 lications to possible new physics in nuclei is the predictive power of firs
 t-principles simulations combined with the possibility to systematically qu
 antify remaining theory uncertainties. I will discuss two applications of a
 b initio nuclear structure theory to predict nuclear structure effects in n
 ew physics studies. In the first\, we identify a nuclear structure effect i
 n high-precision isotope shifts in ytterbium due to higher-order contributi
 ons from the nuclear charge density\, setting bounds on the mass and coupli
 ng of a proposed new boson coupling electrons and neutrons. In the second\,
  we provide precise predictions for leading nuclear contributions to electr
 on to muon conversion in nuclei\, allowing for improved constraints on prop
 osed theories of charged lepton flavor violation. I will conclude with an o
 utlook on future applications to searches for new physics and the new devel
 opments in ab initio nuclear structure theory that will be necessary to tac
 kle these.
