Her work focused on legislation and oversight over the entire energy value chain where she led the team providing legal and technical support for the passage of 11 new energy laws. She is one of the awardees of the Women in Renewables Asia 2019.


Tim graduated with a Masters Degree in Economics from the University of the Philippines School of Economics.

Legal and regulatory frameworks determine the entry of new energy investments and the viability of existing energy businesses. It is crucial to futureproof these frameworks to account for climate risks and to ensure that these regimes do not encourage ventures that further damage the planet. It is a privilege to be part of this specific work that ClientEarth is undertaking.
