As part of our employment law team, I advise our domestic and international clients on a wide range of employment law matters.

In addition to general employment law issues, I have special expertise in employment inventions and other matters at the intersection of employment law and intellectual property law, as well as in residence permits related to work or entrepreneurship.

Before joining Castrén & Snellman, I worked as an Associate Lawyer at another business law firm in Helsinki. I have also experience from working at an international audit firm.

I hold a Master of Laws degree from the University of Helsinki and have also completed law degrees in both Spanish law and European law.

International reinsurance companies – Ad hoc arbitration proceedings
We successfully represented a panel of reinsurance companies in an international ad hoc arbitration. The dispute arose out of a reinsurance treaty under the terms of which the reinsurers had reinsured a portfolio of risks underwritten by the cedent. The parties disagreed as to whether the reinsurance provided coverage for a certain loss that had occurred because of the market turmoil caused by the Covid-19 pandemic. The case involved highly complex legal and contractual questions requiring special expertise on reinsurance law and practice. The arbitral tribunal rejected the counterparty’s claims for reinsurance compensation against our clients in full. The amount in dispute was approximately EUR 34 million.
