A law graduate at King's College, University of London, he qualified as a Chartered Accountant with Arthur Andersen.

Since 2001, Peter has pursued a portfolio non-executive career, becoming Chairman of a number of IT and financial services companies, including LINK, the UK ATM network, in 2003 where he led a major corporate governance change as well as the merger of LINK with Voca, the provider of the BACS service, becoming Chairman of VocaLink in 2007. Among other appointments, from 2012 to 2015, he served as Chairman of the Audit & Governance Committee of East Kent Hospitals NHS Trust, in 2017 was appointed to the board of Redx Pharma PLC, and in 2019 was asked to become Chairman of the Governance & Finance Committee of the Lord's Taverners, a high-profile charity.

As indicated in the announcement of the Company's preliminary results on 28 February 2025, Non-Executive Director and former Chairman Matthew Wakefield has stepped down from the Board, with effect from today.

Iain Ross, Executive Chairman of Oxford BioDynamics, said: "I am very pleased to welcome Peter to the OBD Board. I have seen at first hand the support and challenge he offers in a non-executive capacity. His professional background and extensive experience will complement the Board perfectly and, from a governance perspective, improve the balance of independence among our directors as a group."

"I would like again to extend my thanks to Matthew Wakefield for his service to OBD as Non-Executive Chairman from December 2020 until my recent appointment. Through his leadership of the Board over the last four years, Matthew has been unstinting in his support of the Company and its Management as well as in working to raise funds for the Company on several occasions. On behalf of the Board, I wish him every success in his future endeavours."
