In addition, she has served as an expert witness in a number of cases on deportation and asylum, as well as property restitution and corruption, in American and British courts.
Lavinia Stan is known for her contributions in three major areas: transitional justice, religion and politics, and democratization broadly conceived, with a focus on post-communist Eastern Europe.
In her works on religion and politics in post-communist Romania, Stan made the point that the majority Orthodox Church must be reigned in, if democracy is to be consolidated.
The collaboration of the Church with the communist-era secret police, the Securitate, has been another research topic for her, together with the restitution of property from the Orthodox to the Greek Catholics.
She has authored, co-authored or edited the following volumes: In addition, Stan translated two volumes into Romanian: From 1997 to 2003 she published the quarterly report on the Republic of Moldova in East European Constitutional Review, while since 2006 she has co-authored the annual report regarding political developments in Romania for European Journal of Political Research.
