There are "already many parents" who have contacted the police to stop their children fighting in the Syrian civil war, Dr Usama Hasan told Daybreak.
Dr Hasan, senior researcher at the anti-extremism organisation Quilliam Foundation, said the national awareness campaign to encourage parents to stop their child from fighting alongside jihadis in Syria was "very important" and urged Britain to be "open" about their citizens joining the war.
"Britain should be open about this issue ... hundreds of our fellow citizens are going to these places and let's understand the issue by trying to see what we can do about it," he added.
Greater Manchester Police has joined a national campaign to warn young people of the dangers of travelling to Syria.
An event taking place today, hosted by Greater Manchester Police, will aim to reach out to Muslim women in particular to prevent their loved ones joining the conflict.
The number of people travelling to Syria from the UK is judged to be in the low hundreds and information that is available shows that the number of Syria-related arrests has increased substantially in 2014.
