A lecturer at the University of Oxford’s St Hilda’s College has drawn criticism from colleagues and alumni over his public appearance, which includes wearing women’s clothing, makeup, and oversized prosthetic breasts. Matt Rattley, a biochemistry lecturer appointed in 2023, has been the subject of multiple complaints alleging that his behaviour creates a hostile environment for some students and staff.

At least five formal complaints have been submitted to St Hilda’s College, including letters from three former students—one a leading clinical psychologist—and a parent of a current undergraduate. These complaints argue that Rattley’s conduct undermines the dignity of women on campus and may amount to sexual harassment. They raise concerns about whether his actions violate professional boundaries and contribute to an intimidating or degrading atmosphere.

One Oxford academic described personal discomfort during staff training sessions involving Rattley, saying that his behaviour was distressing and felt akin to being subjected to unwanted sexualisation. The academic recounted an incident during a summer heatwave when Rattley wore a miniskirt with visible underwear, which was considered inappropriate and troubling by those present. Other colleagues attending the sessions reportedly treated his attire as unremarkable, adding to the sense of unease.

Dr Lucy Johnstone, a clinical psychologist and one of the letter signatories, expressed disappointment with the college’s response. She questioned how an institution founded to support women’s education appears to be neglecting safeguards intended to protect female students and staff from potentially harmful conduct.

In response, an Oxford University spokesperson affirmed the institution’s commitment to inclusivity and respect for all community members. The statement emphasized that the university strives to create an environment where everyone feels valued and free to express their identity.

Rattley has not responded to requests for comment regarding the matter. The university and college continue to review the concerns raised.
