Academics from the University of Birmingham have helped to uncover a number of mass graves in Bosnia.
They were part of an international team of experts in satellite imagery, geology and forensic archaeology using new methods to find four sites.
The three academics and the rest of the team assessed changes in the composition of the ground surface.
The International Commission on Missing Persons (ICMP), set up after Bosnia's 1992-95 war, organised the project.
Its laboratory uses DNA techniques to identify victims of conflict or human rights abuses.
Prof John Hunter, who led the Birmingham team, said: "It's coming up to almost 10 years since the massacre of Srebrenica and that was the point at which something in the order of 30,000 people went missing.
"There are still a lot of them unresolved and our job has been to support the ICMP in trying to find where the graves are and to repatriate the victims."
The initial research phase of the scheme was completed on Monday and will be followed by further analysis, the ICMP said.
