PHR has a storied past of significant leadership in mass grave investigations around the world. Our forensic experts played a pivotal role in providing court admissible evidence that helped to support charges and convictions for some of the worst human rights atrocities of the 20th century. PHR’s scientific work in the 1990s in Rwanda and the former Yugoslavia supported the first international courts to prosecute war crimes and crimes against humanity since the Nuremberg Tribunals following World War II.
