The university said in a press release that Madonsela will take up her position in 2018 after a sabbatical.
Madonsela said that she was “supremely honoured” by the offer of the chair in the law faculty.
Outgoing Public Protector Thuli Madonsela's probe into state capture is proof she is a "stooge of white monopoly capital", according to the ANC Youth League.
The league made the allegations at a briefing in Johannesburg. A year ago, the same claims earned MK veterans chairman Kebby Maphatsoe a tongue lashing.
But the youth league is adamant the state is under attack from "imperial forces".
"Mrs Thuli Madonsela is a CIA agent," said league president, Collin Maine.
The league claims because Madonsela did not comment on the allegations the last time they were made is proof enough that the outgoing public protector is on the payroll of US intelligence.
The governing party’s youth wing has slammed Madonsela’s final investigation into the Gupta family and state capture, saying her narrow probe is proof of her bias.
"State capture is not an issue that must only be associated with the Gupta family. We must also talk about the monopoly capital – especially the Stellenbosch mafia. That also should be addressed. If you want to talk about the issue of state capture let's talk about all those things."
Madonsela says she is considering taking legal action against Maine for attacking her person and the office of the public protector.
The youth league has also expressed its opinion on the succession debate in the ANC, agreeing in principle on a female candidate to take over from President Jacob Zuma.
Thandi Moraka, the league's deputy secretary general, said: "We are ready for a female president – but also to say that whoever comes in as president of the ANC must agree with us on the call for free education for the poor, on the call for land expropriation without compensation and on the call for economic freedom in our lifetime."
The league has also called for an immediate end to protests on campuses in order to allow the fees commission to complete its judicial probe into university funding.
