Tipu Zahed Aziz FMedSci is a Bangladeshi-born British professor of neurosurgery at the John Radcliffe Hospital in Oxford, Aarhus Denmark and Porto, Portugal. He specializes in the study and treatment of Parkinson's disease, multiple sclerosis, dystonia, spasmodic torticollis, fixed abnormal posture of the neck, tremor, and intractable neuropathic pain.[1][2] Besides his medical work, he's also notable as a public commentator in support of animal testing.

Early life and education

Aziz was born in East Pakistan (now Bangladesh) into what The Guardian called a “medical dynasty.”[3] He arrived in Britain at the age of 17 with just three O-levels, but after passing A-levels, he studied Neurophysiology at University College London, where he became interested in deep brain stimulation.

He went on to study for a doctorate at Manchester University, where he began his research on animals.


In February 2006, Aziz came to public prominence in the UK when he spoke out in favour of the use of animals in medical research to several hundred demonstrators during a rally held by Pro-Test, a new British group set up to promote the construction by Oxford University of a new biomedical centre in which research on animals will be conducted.[4] Aziz is one of two Oxford neurosurgeons who sit on the Pro-Test committee.[5]

In March 2006, he came to public attention again when he defended the use of animals in cosmetics testing, which is banned in Britain. His comments were described as “perhaps unfortunate” by one colleague.[6]

In June 2012, Professor Aziz was elected a Fellow of the Academy of Medical Sciences.[7]

Research interests

Aziz’s work involves inducing Parkinsonian symptoms in monkeys, either surgically or using drugs, then switching off the symptoms using electrodes he has implanted in their brains. During development of his techniques he has used around 30 monkeys in tests over 20 years, and many believe that as many as 40,000 people around the world have benefitted from the techniques.[8]

The Guardian writes that some patients have described the surgery as “miraculous.” In a 2006 BBC Two documentary Monkeys, Rats and Me: Animal Testing, animal rights philosopher Peter Singer described Aziz’s research as “justifiable” on utilitarian grounds.[9] Singer later clarified his statement saying that it would only be justified, in his opinion, if Aziz were willing to do the same experiments on humans of a similar mental capacity.[10]

Aziz has said that his future research interests will focus on viral, gene, and stem cell therapy to treat Parkinson's and similar movement disorders.

Research criticism

According to The Oxford Student, Malcolm Macleod, a clinical neuroscientist, was asked by Animal Aid to conduct a systemic review into Aziz’s research. Macleod accidentally sent an email intended for a colleague to animal rights group. The e-mail stated he felt that Deep Brain Stimulation was an “area of weakness often trumpeted as a success, but which in reality is probably a failure.” He asked for “advice” and suggested he would "avoid, play a straight bat or price [himself] out of the market” for the review requested.

Animal Aid said about the e-mail “He [Dr Macleod] feared that an objective investigation of the associated animal research would expose the treatment's shortcomings. He was determined to avoid being drawn into the front line of the vivisection debate.”

Dr Macleod claimed that he stood by his choice not to do the review “I was not comfortable taking part in a study which was motivated by a desire to undermine Aziz.”[11]

Animal testing controversy

Aziz has been vocal in support of animal testing and his criticism of the animal liberation movement, calling them “misinformed and sometimes illiterate anti-vivisectionists who adopt terrorist tactics” and who “[undermine] the process of democracy” through “intimidation.” Britain has “probably the most violent and absurd animal rights movement in the world.” he told The Guardian. “The problem with British society is it has a humanoid perception of animals that’s almost cartoon-like.”[3]

On 25 February 2006, he spoke out in favour of animal testing at a rally in Oxford organized by Pro-Test in support of the construction of a new biomedical research center, which will conduct experiments on animals, including primates. Pro-Test was formed to counter SPEAK, an animal rights organisation aiming to end vivisection in the UK.

Defence of cosmetics testing

In an interview published on 4 March 2005, Aziz condoned testing cosmetics on animals, a practice banned in the UK since 1998 and due to be banned across the European Union by 2009. He said that to argue cosmetics testing is wrong is “a very strange argument,” and that “[p]eople talk about cosmetics being the ultimate evil. But beautifying oneself has been going on since we were cavemen. If it’s proven to reduce suffering through animal tests, it’s not wrong to use them. To say cosmetics is an absolute evil is absurd.”[3]

Other scientists who use animals in research have “distanced themselves” from Aziz’s remarks. Clive Page, a researcher at the University of London, said: “I don't think we can justify using animals for cosmetics research. [Prof Aziz], like myself and a few others who talk out about this have worked very hard to try and explain to the public why we do medical research on animals and why it’s still necessary. To muddy the waters by bringing back an issue of using animals for something that’s not actually approved in the UK is perhaps unfortunate.”[6]

Simon Festing, director of the pro-animal experimentation lobby group Research Defence Society said of Aziz: “He’s not involved in cosmetic testing himself, [Britain’s] not involved in cosmetic testing, it's been banned here. There’s no movement from the scientific community or the cosmetics industry to have it brought back in. I can’t see it being particularly relevant apart from being his personal view.”[6]


An animal rights campaign has formed around a seven-year-old macaque monkey that Aziz has used in his research. Named Felix by Aziz himself, he is one of 100 purpose-bred monkeys used in animal experiments by Oxford University.[12] Felix was featured in a November 2006 BBC documentary about Aziz’s work, “Monkeys, Rats and Me.” The monkey was shown being “shaped,” that is, being encouraged to perform certain tasks by having food and water withheld, in advance of having the symptoms of Parkinson's disease induced. Electrodes were implanted in his brain to test the effects of deep brain stimulation on the Parkinsonian symptoms and on his ability to perform the tasks. He will be destroyed at the end of the experiment, which could continue for several years.[8][12]

Since the BBC documentary aired, SPEAK, a British animal rights campaign formed in 2002, has focused on the “Fight for Felix” as a symbol of their efforts to halt the construction of a new £20 million animal-testing facility in South Park Road, Oxford[13]
