Hedge funds seeking artificial intelligence expertise need to cast the net wide these days, due to a shortage of people and a massive uptick in demand over the past 12 months.

Citadel has just turned to Microsoft for the new role of chief AI officer. Li Deng, who joined the tech firm straight out of academia 17 years ago, has just joined Citadels hedge fundoperation inSeattle, but will work also across Chicago and New York.

Deng announced his move to Citadel on LinkedIn yesterday, saying that he was very excited about the opportunities for artificial intelligence innovation here and the firms passion for growing its leadership in this space. Citadel didnt immediately respond to requests for comment.

Deng was chief scientist of AI and partner research manager at Microsoft. He joined in December 1999 from Waterloo University in Washington where he was a professor. He clearly has a passion for expanding AI knowledge he headed up Microsofts AI school, as well as founding its deep learning technology centre.

Citadel is the latest big buy-side firm to create a new role heading up AI and machine learning as hedge funds rely on ever-more complex datasets to gain an edge over the competition.

Man Group brought in William Ferreira as head of machine learning for its discretionary hedge fund business GLG in April. It was a newly-created role and he previously worked at Florin Court Capital. David Ferrucci, who previously headed up IBMs development of super-computer Watson, joined Bridgewater Associates in 2012 and now heads up its AI function, the Systematized Intelligence Lab, which has been growing this year

Hes kept his hand in academia, and was affiliate professor at the University of Washington for over 17 years until he joined Citadel in May. Hes written numerous books on using deep learning for automatic speech recognition as well as deep learning applications and methods.

Citadel already has a head of machine learning. Pradeep Natarajan joined from Amazon, where he was a senior research scientist, in October 2014.

Its also its second stab at poaching from Microsoft it brought in Kevin Turner, the tech firms ex-COO as CEO of Citadel Securities in August last year, but he left just seven months later. Hes now founder and CEO of his own start-up Forward Progress Ventures.
