About Me

I'm a corporate partner based in London where I advise clients – ranging from start-ups to multinationals as well as venture capital and private equity funds – on mergers and acquisitions (and divestitures), securities transactions, private equity and venture capital investments/exits, joint ventures and corporate reorganisations.

I have extensive experience advising clients in a variety of sectors, with a particular emphasis on the life sciences and healthcare, technology, media and telecoms and retail and consumer sectors. Many of the transactions I advise on are in cutting-edge sub-sectors – which oftentimes require specialist legal expertise from experts across the firm – such as artificial intelligence (AI), biotech, blockchain, cyber, deep tech, health-tech, medical devices, quantum computing, software and robotics, among others.

You'll find me ranked in the Legal 500 UK 2024 legal directory as a Next Generation Partner in both the fields of Venture Capital and Life Sciences and Healthcare. I also advised on a number of transactions which helped the firm to win both the EMEA M&A Law Firm of the Year and the EMEA Venture Capital Law Firm of the Year awards at the LMG Life Sciences Awards EMEA 2023 in July 2023.

Clients retain me for my 20 years of experience and successful track record of executing transactions, as well as my focus on providing clients with pragmatic and commercial advice. Many of the transactions I am involved in are international in nature and I therefore have significant experience in solving complex cross-border legal issues and bridging cultural differences.

I am admitted as a Solicitor of the Senior Courts of England and Wales and the Eastern Caribbean Supreme Court in the British Virgin Islands and I hold an LL.B. in Law with Economics from Durham University. I also serve on the Finance and Tax Advisory Committee of the BioIndustry Association.
