Our People

CHPI is not affiliated to any political party and produces independent, evidence-based research.

The Centre employs three members of paid staff. We produce and disseminate policy reports and research-based analyses in collaboration with a network of expert contributors.


David Rowland


David Rowland was appointed as CHPI’s first Director in 2019 after over a decade of working in senior policy positions within the healthcare regulatory sector.

He has played a key role within healthcare professional regulation as the Head of Policy at 3 national regulators (The General Social Care Council, The General Dental Council and The General Optical Council) and has developed significant expertise in social care policy, NHS workforce issues, regulation, safeguarding, whistleblowing and EU health policy.

He has also been involved in the development of the CHPI since its inception in 2011, committing significant amounts of his spare time to building the Centre and working with its Executive Management Team to develop a research strategy, build the Centre’s profile in the media and in Parliament, and raise funds.

Prior to working in healthcare regulation David was a research fellow at the School of Public Policy, University College London where he undertook research on the Private Finance Initiative and social care markets with Professor Allyson Pollock and Professor Colin Leys. He also worked with Professor Scott Greer on a series of Nuffield Trust funded projects which examined EU health policy, the management of the NHS and Communicable Disease Control administration.

He has used his academic expertise as well as his experience of developing national policy on healthcare regulation to add to the Centre’s research output and has been responsible with Colin Leys for leading the Centre’s work on patient safety in private hospitals and with Vivek Kotecha on the Private Finance Initiative.
