Our Scientist Leaders help participants know the natural world through hands-on field research and discovery.

Earthwatch Expeditions' Scientist 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 continued immersion. Many have discovered new species, built invaluable long-term datasets and shaped conservation efforts worldwide.

You'll find that they are exceptional people to spend time with—they're welcoming and warm, generous with their knowledge, and thoughtful in their instruction. From Principal Investigators to the broader field team, our Scientist Leaders foster environments that are inclusive, engaging and driven by curiosity.
