In the rarefied world of conservation science, our Scientific Leaders help travelers understand the natural world through hands-on field research and discovery.

Earthwatch Expeditions' Scientific Leaders bring clarity to the science behind each adventure and invite curious travelers into their work as active participants. They are accomplished researchers with distinguished credentials from leading academic institutions. Many return to the same ecosystems year after year, building a depth of knowledge that only comes from time, patience and immersion. Many have discovered new species, built invaluable long-term datasets and shaped conservation efforts worldwide.

They are also exceptional people to spend time with. They are welcoming and warm, generous with their knowledge and thoughtful in their instruction. From Principal Investigators to the broader field team, our Scientific Leaders foster environments that are inclusive, engaging and driven by curiosity.
