Professional background

Professional background

I am an Amsterdam-based corporate partner and have been practising since 2010. I act for both buy and sell side, strategic parties and investors and focus on complex transactions like (international) investment strategies, carve-outs, spin-offs and (multi-party, multi-role) joint ventures. My practice mostly, but not exclusively, evolves around transactions in regulated or otherwise governmental influenced industry sectors like (renewable) energy, life sciences and defence.

Although being a sector-independent corporate lawyer, I have ample experience in transactions in the energy sector (both hydrocarbons, renewables and other sustainability initiatives). Having worked as in-house counsel for two years at a Dutch manufacturer for offshore oil & gas equipment, and later being seconded to the Dutch market-leading developer of ground-mounted and floating solar farms, I have broad experience in the development of energy projects. I also advise on regulatory aspects of energy (electricity and heat).

I am a member of the Fieldfisher's Energy & Natural Resources, Life Sciences, Cannabis and Space & Defence global sector teams.

Legislative developments in the combat against e-grid congestion in the Netherlands

Electricity grid congestion (e-grid congestion ) remains one of the most significant challenges in Dutch society. The lack of transport capacity and connection availability result in a standstill in the development of housing, commercial locations and heavy industry. Annual societal damages are estimated to be between EUR 10 and 40 billion.[1] As of December 2025, the waiting list for obtaining a connection or increase in transport capacity consisted of 15,000 requests.
