I tell stories about security, development, culture and human rights, using a range of media, including text, video, audio and photography. I report on violent extremism in Africa, in particular in Kenya and Somalia. I covered the brutal attack on Nairobi's Westgate shopping mall in September 2013: in the aftermath, I interviewed survivors and first responders, including retelling one of the most dramatic stories of the massacre

I followed the trail of the world's 'most wanted woman', Samantha Lewthwaite, and covered the deepening tensions in Kenya's "war on terror". I exposed the earlier arrest of Woolwich killer Michael Adebolajo on suspicions of trying to join Somali militant group al-Shabaab.
