I am Co-Head of Lewis Silkin’s Data, Privacy & Cyber Group. I work in three main areas: data, privacy & cyber; commercial & consumer; and technology.

Although my main area of focus is data, privacy & cyber, I have a commercial & consumer and technology background so regularly advise clients across all three practice areas.

From a data, privacy & cyber perspective, I have advised a number of high profile clients on a range of complex data protection issues particularly around data collection and commercial exploitation and corporate governance. I also have also been involved in a number of high profile data regulatory investigations for large multi-national clients as well as advised on various data breaches. I hold the IAPP CIPP/E data protection/privacy accreditation and have spoken at a number of events on data, privacy & cyber issues.

From a commercial, technology and consumer perspective, I have a wealth of experience advising clients on both demand and supply side on a range of commercial agreements including supply of goods/services, software licensing & distribution, cloud services, agency and distribution, franchising, warehousing and logistics, sponsorship and ticketing, client/agency, media buying and confidentiality.  I have also advised on e-commerce compliance and general consumer law issues and have been involved in a number of consumer regulatory investigations acting on behalf of well-known retailers.

My particular areas of specialism are retail and adtech and I am part of the Lewis Silkin’s Retail Law Group and Lewis Silkin’s Advertising and Marketing Law Group
