He is a member of the Society for Psychical Research and an advisor to The Ghost Club.

			== Hampton Court Palace investigation ==
			O'Keeffe was part of an academic team, working alongside Wiseman, that investigated Hampton Court Palace — reputed to be one of the most haunted locations in England — to test three competing explanations for reported hauntings there: prior belief in ghosts, suggestion, and magnetic fields. More than 600 members of the public took part, completing questionnaires on their belief in ghosts before being given either a positive or negative "suggestion" about recent unusual activity at the palace and encouraged to walk its rooms reporting anything they experienced. The study found reported experiences were significantly associated with both prior belief and the suggestion given beforehand, and the data offered some support for a relationship between local magnetic field variation and where experiences were reported.<ref name="psi" />

			== Environmental correlates of hauntings ==
			In 2020, O'Keeffe and colleagues published a comprehensive review updating earlier 2001 work on the environmental correlates of poltergeist and haunting experiences, examining 66 studies across two decades of research. The review identified six recurring environmental variables proposed to contribute to haunting reports — embedded static cues, lighting levels, air quality, temperature, infrasound, and electromagnetic fields — but concluded that none of these, alone or combined, offered convincing explanatory power on their own, pointing instead toward more holistic explanations such as "simulation theory" as a more productive way to understand reported hauntings.<ref name="psi" />

			== "Ghostwatch Revisited" ==
			In a 2012 article marking its twentieth anniversary, O'Keeffe examined the notorious 1992 BBC broadcast ''[[Ghostwatch]]'', a scripted drama presented as a live investigation that caused significant public panic and was linked to a viewer's death by suicide. Sceptic Susan Blackmore, quoted in the piece, criticised the programme for treating its audience unfairly and failing to give adequate warning of its content. O'Keeffe concluded that the extreme viewer reactions stemmed from the programme's departure from established horror-genre convention — where the instability caused by a paranormal threat is eventually resolved — since ''Ghostwatch'' instead sustained its threat continuously throughout.<ref name="psi" />

			== Quantifying ghostly encounters ==
			In a wide-ranging review with co-authors, O'Keeffe helped identify 28 core experiences commonly reported across haunting and poltergeist cases, spanning both subjective experiences typical of hauntings and the more physical, objective manifestations typical of poltergeist-type disturbances, aiming to give future investigators a more standardised framework than existing case studies, surveys, and field research had provided.<ref name="psi" />

			== Ethical guidelines for haunting investigations ==
			In a 2007 paper co-authored with Ian Baker, O'Keeffe set out ethical guidelines for haunting investigations, prompted by the rapid growth of amateur and professional ghost-hunting activity and the absence of any governing body for the field. The guidelines address informed consent and confidentiality, offer methodological advice on interviewing and overnight location investigations, and examine the pastoral responsibilities an investigator owes to witnesses, including when to refer them to other professional support.<ref name="psi" />

			== Testing mediums ==
			In a 2005 paper with [[Richard Wiseman]], O'Keeffe reported a double-blind test of mediumship designed to eliminate flaws identified in earlier research — sensory leakage, overly general statements, and non-blind judging. Five mediums each gave a reading to a sitter unknown to them, located in a separate room; sitters were then given the resulting statements, broken apart and mixed with material from other sittings, and asked to identify which applied to them. The ratings did not reach statistical significance.<ref name="psi" /> A later 2020 review by researcher Patrizio Tressoldi, examining more recent and methodologically rigorous mediumship tests generally, reported finding highly significant evidence for anomalous information transfer — a conclusion in tension with O'Keeffe and Wiseman's own earlier null result.<ref name="psi" />

			== "Haunted People Syndrome" ==
			O'Keeffe and co-authors have also explored whether a distinct "Haunted People Syndrome" (HP-S) exists — a pattern of recurrent, systematic anomalous perceptions that, depending on the person's interpretive framework, might be understood as spirits and hauntings, or might instead take the form of perceived gang-stalking or surveillance. Rating published gang-stalking accounts against a standard measure of haunt-type anomalies, the researchers found significant overlap between the two categories of experience, consistent with a single underlying HP-S construct.<ref name="psi" />

	O'Keeffe joined ''[[Most Haunted]]'' as its parapsychologist, replacing [[Phil Whyman]], and became known for providing a sceptical, evidence-based counterpoint to the show's on-camera investigations. In 2005, he devised a test in which he fed [[Derek Acorah]] fabricated background details about entirely fictitious spirit entities — "Kreed Kafer" and "Rik Eedles," anagrams of "Derek Faker" and "Derek Lies" — before an investigation. Acorah went on to describe contact with them on camera as though they were real, and O'Keeffe's exposure of the test became one of the best-known moments in British paranormal television.

	O'Keeffe later said he had been misquoted in press coverage of the incident, clarifying that his test had been aimed specifically at Acorah rather than at the programme or its wider team.

	== ~~Research~~ ==		== Books ==
	~~Outside television,~~ O'Keeffe ~~has been involved in academic~~ investigations ~~seeking natural explanations for reported~~ hauntings, ~~including studies into the physiological effects of low-frequency infrasound~~ and ~~a multi-researcher investigation of Hampton Court Palace~~. He co-authored ~~the 2003 paper "An investigation into alleged~~ '~~hauntings~~'~~" in~~ the ''~~British Journal of Psychology'' alongside Richard Wiseman~~ and ~~others~~, and ~~has published further research on~~ the ~~environmental correlates of~~ [[~~poltergeist~~]] ~~and haunting experiences~~. ~~He also~~ co-authored ~~the book~~ ''~~[[Ghost Hunters: A Guide to Investigating the~~ Paranormal]]'' with ~~[[Yvette Fielding]]~~.		O'Keeffe co-authored ''[[Ghost Hunters: A Guide to Investigating the Paranormal]]'' (2006) with [[Yvette Fielding]], drawing on cases from their own investigations alongside a broader guide to hauntings, orbs, and poltergeists. The pair also co-authored ''In Search of the Supernatural'' (2008), investigating paranormal sightings across the UK and abroad, including the tunnels beneath [[Liverpool]] and the Devil's Arse cavern in the [[:Category:Derbyshire\|Peak District]]. Separately, O'Keeffe co-authored ''The Great Paranormal Clash'' (2008) with stage psychic Billy Roberts, structured as an exchange of opposing perspectives between the two.<ref name="psi" />
