Her practice focuses on tech, automotive/EV, retail/consumer and clean energy industries.

Being based in Brussels, she has wide experience supporting clients’ interests in relevant files going through the EU legislative process in the EU institutions. She also specialises in different aspects of tech and sustainability regulation, including net neutrality, DSA, DMA, autotech, CBAM, EUDR, EUBR and DPPs, and green washing. Siobhan sits on the Law Society of Scotland’s Council and is Convener of its International Committee.
