Tom joined the BBC as a general news reporter in 1990, interviewing Mikhail Gorbachev on a train to Cornwall for Radio 1 and covering the conflict in Rwanda before joining the Today programme.
After a brief stint at Newsnight, Tom returned to Today to focus on science and the environment. He covers an eclectic mix of developments in physics and astronomy, medicine, genetics, wildlife and climate change - from super massive black holes to preserving adder habitats.
A former presenter of Radio 4's Costing the Earth, he won a Foreign Press Association award for his series on wildlife in Britain in 2000, and a British Environment and Media Award for his coverage of climate change in 2001.
He should have been part of the Sony award winning team that covered the launch of the Large Hadron Collider at CERN in 2008, but sadly the giant atom smasher broke shortly before the awards ceremony and the judges looked elsewhere.
Born in 1964, Tom graduated from Sussex University in 1986. He lives in north London with his partner and three children.
