Medium Effects in Parton Distributions
  Understanding the effects of a background hadronic medium on hadronic observables is important in the context of hadron structure. Many experiments probing nucleon structure make use of nuclear targets and unraveling the modifications that ensue is a complex task. Using lattice QCD, we investigate the ab initio computation of hadron structure in a medium, focusing on the structure of the pion in a Bose-condensed gas of pions.
