Saba Mozakka was one of the family representatives who helped guide creation of the memorial
A permanent memorial is being unveiled in London's Hyde Park, four years after suicide bombers killed 52 people and injured hundreds more by detonating backpacks loaded with explosives on the city's transport network.
Tall and imposing, the 3.5m (11.5ft) tall stainless steel pillars - or "stelae" - tower above those who wander in between.
There is one for each victim of the bombs that wrought chaos and destruction across central London on 7 July 2005.
The pillars are grouped into four clusters, symbolising the four attack sites - King's Cross, Aldgate and Edgware Road on the Underground and Tavistock Square, where the last of the explosions hit the number 30 bus.
The casting process has ensured that each stelae - while produced from the same mould - has unique characteristics.
Among the names of victims listed on a nearby plaque is that of Behnaz Mozakka, a 47-year-old biomedical officer at Great Ormond Street children's hospital and mother of two, who died aboard a Piccadilly Line Tube train near King's Cross.
It's a huge responsibility to deliver something meaningful on behalf of the bereaved families
