A member of EHRI Working Groups on Dissemination (WP2) and New Methodologies, Data Identification and Integration (WP9), Ján Hlavinka is a researcher at the Holocaust Documentation Center as well as at the Institute of History of the Slovak Academy of Sciences in Bratislava, Slovakia.
In 2002 I started my career as a researcher at the Museum of Slovak National Uprising in Banská Bystrica and couple of months later I moved to the Nations Memory Institute in Bratislava (2003-2008). There I co-developed and later led the project focusing on the documentation of the Holocaust. The project included the gathering of sources for later published databases as well as the academic research. In 2007 I published my first monograph focused on the victims of Holocaust from the district of Medzilaborce.
