I'm an independent journalist who specialises in investigative news projects. I'm also an author and a photographer.
I've been a member of the National Union of Journalists for 27 years. A few of the organisations I've worked with are listed on the right.
Recent projects have included an investigation for the Mail on Sunday into the rise of moped-enabled crime by gangs in London.
I've written two books about jihadism and terrorism, called Terror Tracker and Terror Base UK.
As an expert in areas that include extremism and political violence, technology, and social media, I'm often asked to provide an expert opinion on these subjects, as can be seen in a piece in The Times.
I've been experimenting with technology and photography since the 1980s.
