Malcolm Taylor

Dr Malcolm Taylor was a UNIT scientific advisor at the time of the incident involving the Swarm.

Early life
Dr Malcolm Taylor was a Welshman and one of UNIT's scientific advisors, considered by Captain Erisa Magambo to be a genius. He read all of UNIT's files on the Doctor, coming to idolise them, and came up with units of measurement named after himself and Bernard Quatermass. (TV: Planet of the Dead)

2000s
Malcolm worked out how to close the wormhole created by the Swarm before the Tenth Doctor. Magambo ordered him to close the wormhole to protect the Earth, despite the Doctor and the passengers of Bus 200 being trapped on the other side, but he refused. Once the Doctor and the passengers made their way through, the Doctor called Malcolm to close the wormhole. In his excitement Malcolm repeatedly hung up on him, but nevertheless complied, closing the wormhole just ahead of the main swarm. After Malcolm met the Doctor for the first time in person, he hugged him and repeatedly proclaimed "I love you!" The Doctor, bemused, pointed to Malcolm affectionately as he walked away. (TV: Planet of the Dead)

Malcolm was good friends with Martha Jones, who would occasionally fill in for him even after she had left UNIT. (COMIC: Don't Step on the Grass)

2010s
In 2013, Kate Stewart told Osgood to tell Malcolm to replace the batteries of the ravens of death. After being alerted to the presence of more than one Doctor in one place, Kate ordered Malcolm to send her one of her father's old files code-named "Cromer". (TV: The Day of the Doctor)

Malcolm headed the clean-up team which investigated the site of 's apparent death (PROSE: The Secret Diary of the Master) at the hands of the temporarily-resurrected Alistair Gordon Lethbridge-Stewart. (TV: Death in Heaven) When his team discovered the Masterplan Journal, the Master's diary, he had its contents transcribed to a digital format and emailed them to Kate and the rest of UNIT Command. (PROSE: The Secret Diary of the Master)

Malcolm set up a hologram of the Tower of London while it underwent reconstruction after the Tengobushi attack (AUDIO: Ice Station Alpha) and later assisted Kate and Osgood in the 2010s. (COMIC: The Lost Dimension) It was thanks to Malcolm's immunisations that Osgood was unaffected by John Torrance and Christine Colley's Veralium truth serum. (AUDIO: The Sontaran Project)

When a shipping container appeared at Windsor Castle, Malcolm tried to scan it but informed Colonel Vikram Shindi that he could not get any signals. (AUDIO: Game Theory) Osgood later said that it would take months for Malcolm to disassemble and catalogue all of the Auctioneers' artefacts stored at the Whitehouse Gallery. (AUDIO: Master of Worlds)
