Apple CEO Tim Cook is to receive an honorary doctorate of science from the University of Glasgow at a ceremony later today followed by a 'fireside' chat and Q&A.

The 56-year-old will address students and staff at an event in Bute Hall from 6pm GMT and topics are likely to include Apple's focus on green energy, privacy concerns and his company's charity work. The free, hour-long event is said to have sold out within 60 minutes of going on "sale" on Eventbrite.

In a post announcing the event, the university praised Cook for "the introduction of innovative new products and services" and for leading a "companywide effort to use 100 per cent renewable energy at all Apple facilities".

In 2015, Cook ranked number one on Fortune’s World’s Greatest Leaders list, and received the Ripple of Hope award from the Robert F. Kennedy Center for Justice and Human Rights and the Visibility Award from the Human Rights Campaign.

The same year, the 56-year-old became an honorary patron of Trinity College Dublin's Philosophical Society and received an honorary degree from George Washington University. He additionally has a degree in industrial engineering from Auburn University, Alabama, and an MBA from Duke University in North Carolina.
