What does it take for Cambridge University to expel a student?

(a) making threats to kill a fellow student?

(b) raping a fellow student?

(c) setting fire to a fellow student?

(d) sending emails?

We thank Dr Nuno Oliveira for his testimony below.

I know the answer — because it happened to me.

I am one of the very few students ever expelled by University of Cambridge — recently ranked the UK’s best employer by the Financial Times. On 30 April 2026, I received a notice from the Office of Student Conduct, Complaints and Appeals (OSCCA):

“With immediate effect, you are permanently excluded from membership of the University… You will not be able to complete your PhD … You will not be able to return in the future.”

That was the outcome of an “investigation” launched after I raised complaints about harassment and research misconduct by senior academics — complaints that were never addressed.

Instead, after 36 months of persistence on my part, those involved — and those who had enabled the cover-up — produced witness statements against me. Statements I was never allowed to see.

The issues began in the Department of Applied Mathematics and Theoretical Physics (DAMTP) during my time as a postdoctoral fellow. Yet the consequences were imposed on my part-time PhD in a completely different department, History and Philosophy of Science (HPS) — one with no connection to the original misconduct.

The University took my job and my research, disregarded the terms of my UKRI grant, ignored every complaint I filed and provided misleading information about my rights

It failed to follow its own whistleblowing and safeguarding policies.

I was placed under sweeping “precautionary measures,” effectively silencing me by barring me from contacting senior leadership, HR, and colleagues by email. It prevented me from speaking to co-authors on my own research and restricted my discussions with a senior professor willing to help. Even my personal belongings — essential for my research — were withheld.

And throughout it all, the list of people aware of these events grew: the University Council, General Board, Board of Scrutiny, Proctors, and College leadership. No one intervened.

What stays with me is not just the lack of support — it’s the message that silence sends.

It tells those responsible that they are untouchable. It tells others that speaking up comes at a cost.

Over the past three years, I have learned how reputation management can eclipse truth. How institutions protect themselves first. And how easily individuals can be erased when they challenge power.

Still, they failed to break me.

If anything, this has only strengthened my resolve to speak out—so others do not have to endure the same.

This is not just a personal story. It reflects a deeper failure across UK higher education.

An institution celebrated globally for excellence has, in this case, demonstrated something else entirely: poor governance, lack of accountability, and a system where hierarchy overrides truth.

The 21 Group applauds Dr Oliveira for his persistence and courage.
