Complex public projects tend to go well or badly depending on whether the people involved can see what's actually happening. I learned that over four years on the Broadway Subway Project, one of BC's largest infrastructure investments, where I led community and government relations for half the corridor and was the team's expert on stakeholder data. I've also worked on engagement design for regional policy initiatives and on data and climate policy for clients from PwC to municipal governments.

Today I advise climate organizations, nonprofits and civic campaigns on the systems their work depends on, including how to put cheap, capable AI to work inside them without losing public trust. Much of my attention goes to Canada's biggest bets in power, critical minerals and resilience. The question I keep returning to is how a country of Canada's size builds more of the right projects, ones that hold their value instead of becoming stranded assets.
