Julio Campis Díaz is a 24-year-old Puerto Rican ecologist and PhD student whose career took a dramatic turn the day he stepped into El Yunque National Rainforest. What began as a required research assignment led him from freshwater shrimp studies to working inside Great Smoky Mountains and Yosemite National Park.

In this episode Julio shares how that moment reshaped his path, the mentors who guided him, and the field experiences that shaped his love for conservation. He talks about tracking rare owls, teaching visitors in national parks, witnessing shrimp migrations, and navigating close encounters with wildlife. We also discuss the challenges national parks face today and the importance of including native knowledge and strong community partnerships.
