As an Associate at Mann Lawyers specializing in corporate and environmental law, I bring a decade of experience in biodiversity research and international sustainable development, with work spanning Canada, the U.S., Malta, and Indonesia. Before law, I managed a global wildlife conservation research office, led research expeditions in Indonesian tropical rainforests, and contributed to wildlife conservation as a published scientist.  I also served as a Senior Project Officer at the United Nations Association in Canada, where I secured green economy jobs and placements for youths at United Nations agencies worldwide.

I have a Bachelor of Science in Earth Systems (Magna Cum Laude, University of Malta), a Master of Environmental Science (University of Toronto, Rotary Scholarship Funded), and a Juris Doctor (Cum Laude, University of Ottawa). During law school, I interned with Senator Pierre J. Dalphond focusing on Indigenous legal issues and led the University of Ottawa’s Environmental Law Students’ Association.

I was called to the Ontario Bar in 2024 and earned a Certificate in ESG, Sustainability, Climate Risk and the Law from Osgoode Hall in 2025.

I specialize in Environmental Litigation. Alongside Michael S. Hebert, I am litigating Canada’s first—and currently only—certified class action concerning PFAS. Representing hundreds of class members affected by PFAS contamination and resulting property value loss, I navigate this rapidly evolving legal frontier by applying emerging scientific and regulatory standards and advancing novel legal arguments at the intersection of environmental science and law.

I am fluent in English and Maltese, with conversational proficiency in Arabic, Italian and Indonesian. Outside work, I am a musician and active in the Rotary Club of Ottawa South.
