Following the war, he took up a position as a senior demonstrator at the University College, London in 1920 at the behest of Grafton Elliot Smith, famed anatomist, anthropologist and fellow Australian. This would be followed by a year on a Rockefeller Foundation Fellowship at Washington University, St Louis, Missouri. Returning to England and work at the University College, London, he then reluctantly took up the position of Professor at the newly established department of anatomy at the University of the Witwatersrand in Johannesburg, South Africa in 1922, after encouragement from Elliot Smith and Sir Arthur Keith.
