How a conservation entrepreneur is tackling snakebite, restoring ecosystems, and building impact from the ground up, with our guest Dr Harry Fonseca Williams.
Have you ever wondered what happens when you combine a passion for wildlife with the drive to actually make a difference?
Today’s guest is Dr Harry Fonseca Williams - a toxicologist, conservationist, and founder who is working at the intersection of science, entrepreneurship, and conservation impact.
Harry describes himself as a “snakebite scientist” with a passion for toxic animals, and in this episode we explore two sides of his work. First, his role in founding The LEAF Charity - a fast-growing organisation restoring ecosystems and supporting communities through large-scale tree planting and conservation projects. And second, his work with ToxiVen and beyond, developing cutting-edge diagnostics and treatments to tackle snakebite - one of the world’s most overlooked global health challenges.
We talk about what it really takes to build a conservation charity from scratch, how small ideas can scale into meaningful impact, and why turning research into real-world solutions is so important.
We also dive into Harry’s career journey, from studying venom pharmacology to launching companies and leading conservation projects, and the lessons he’s learned along the way - including the importance of collaboration, fundraising, and following your passion.
If you're interested in conservation careers that go beyond the traditional path - blending science, startups, and real-world impact - this episode will give you plenty to think about.
It’s a snakes, science, impact podcast.
Enjoy.
