Currently Archdeacon of Croydon, Dr Mallett was born in Barbados and grew up in the UK.
She trained for ministry at the South East Institute of Theological Education (SEITE) and served her curacy at Christ Church, Brixton Road. She was ordained Priest in 2005.
Dr Mallett was educated at Sussex and Warwick Universities and before ordination was a research sociologist and academic specialising in international development and ethno cultural mental health.
Dr Mallett will be the second Barbadian born Bishop of Croydon, following the Rt Revd Wilfred Wood, the first black bishop in the Church of England, who served as Bishop of Croydon from 1985 to 2003.
Dr Mallett said: “I am thankful to God for the honour and privilege of serving as the next Bishop of Croydon. I love the diversity of this area geographically, ethnically and culturally.
“I will serve the Episcopal Area of Croydon and East Surrey and the people with great pride and do my very best to make God’s word and his love be known, while championing social justice causes across the area for people of all ages.”
