Osiris de Carvalho

Osiris de Carvalho is a Senior Litigation Manager in Bailey Glasser International’s London office. He is a lawyer qualified in Brazil and Portugal and also trained as a data analyst. His work combines legal project management, damages quantification and data analysis, with a particular focus on complex group litigation and international investigations. Before joining BGI, Osiris worked at Pogust Goodhead, where he led litigation project-management, claimant-data and loss-quantification workstreams in Município de Mariana v BHP, the English group litigation arising from the 2015 Fundão dam collapse in Brazil. His work supported a claimant population of more than 620,000 and involved close collaboration with partners, counsel, economists, scientific experts and data specialists.

 Osiris has particular experience translating legal principles, factual evidence and expert assumptions into analytical frameworks for assessing losses across large claimant groups. His work includes damages modelling, claimant questionnaires, disclosure coordination and the development of tools to support evidential analysis and litigation strategy. He combines this analytical work with the planning and coordination of complex litigation, aligning legal, expert and operational workstreams with court timetables.

 Earlier in his career, Osiris held senior roles at Lineal, FTI Consulting and Forensic Risk Alliance, supporting leading law firms on complex disputes and regulatory investigations across multiple jurisdictions. At Forensic Risk Alliance, he played a key project-management role in the Airbus global bribery investigation. His experience encompasses large-scale electronic disclosure, technology-assisted review and the coordination of multilingual review and document-production teams.
