  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.
