|Amelia, host of ARCA's summer program|
I recommend becoming involved in ARCA (the Association for Research into Crimes against Art) the nonprofit I work with.
If you are interested in learning about prospective employers in the area, then consider the ARCA Postgraduate Certificate, which has a broad scope, and offers career-building and networking opportunities. The summer program brings together experts in law, art history, criminology—and most importantly has practical courses for insuring, protecting and recovering illicit art.
