 She showed how the physics of [[quarks]] can be used to predict certain aspects of the physics of [[hadrons]] (which are particles made from quarks) regardless of the details of the hadron's structure (with [[Enrico Poggio]] and [[Steven Weinberg]]).This useful property is now known as [[quark-hadron duality]].She has given public talks in various countries on "[[CP violation|The Missing Antimatter]]", in which she suggests that this area of research is promising.
