After six years of service in the United States Air Force, Evan McArdle, class of 2025, found a new mission: protecting the planet. Initially pursuing psychology at West Chester University, he realized his true calling lay in environmental science. That realization brought him to the University of Delaware, where he began his studies in Environmental Studies in 2022. It was there that he discovered an unexpected passion beneath the surface, scuba diving.
Through UD’s diving courses, from introductory to advanced and scientific diving, Evan quickly found that working underwater came naturally. His skills led him to join Project Recover on a 2024 study abroad program in Micronesia, where he supported underwater research alongside UD faculty and students. The experience solidified his commitment to environmental stewardship and inspired him to explore new ways to merge science, hands-on fieldwork, and impact-driven innovation.
When government restructuring in early 2025 made traditional environmental positions harder to find, Evan began looking for new ways to channel his skills. Encouraged by UD faculty who recognized his potential, he was introduced to the Eco-Entrepreneurship course and, soon after, the REEF@UD Fellowship, opportunities that would allow him to apply his environmental knowledge and diving experience in unexpected, entrepreneurial ways.
What inspired you to apply to the REEF@UD Fellowship?
I was contacted by faculty who shared some of the student-led projects focused on marine ecosystems. They thought my background in diving and environmental science could help take one of those ideas to the next level. After reviewing the projects, I became excited about their real-world potential and wanted to be part of creating something that could make a global difference.
Please describe your project or venture. What environmental challenge are you tackling, and how?
The venture focuses on coral restoration and reef protection by partnering with the hospitality sector, an industry not traditionally associated with conservation efforts but one that depends heavily on healthy marine ecosystems.
Our approach has three main components:
- Coral Nurseries: Installing coral nurseries in areas frequented by cruise lines, hotels, and resorts, using University of Delaware intellectual property and enhanced nursery tree designs to promote coral growth and resilience.
- Educational Experiences: Creating interactive opportunities for guests to learn about coral science and witness restoration work firsthand — turning tourism into education and advocacy.
- Student Opportunities: Developing internships for university students that can lead to long-term career pathways in marine conservation or eco-tourism.
Ultimately, this venture serves as a bridge between government and academic restoration programs and the broader public, connecting science, policy, and the hospitality industry.
What was a highlight of your REEF@UD experience?
Definitely the Demo Day. Seeing all of the participants’ ventures gave me so much optimism about the future of our planet. It was inspiring to witness so many creative, science-driven solutions aimed at protecting and regenerating our environment.
What’s one skill or insight you’re taking away from the program?
Before REEF@UD, I wasn’t business-oriented at all. I viewed environmental challenges purely through a scientific lens. The program helped me understand that entrepreneurship can be a powerful force for good when used responsibly. I’ve learned to think like an entrepreneur, to identify problems, innovate solutions, and take action, while keeping sustainability and regeneration at the heart of every idea.
What advice would you give to future students thinking about applying to REEF@UD?
Even if you have no background in business or entrepreneurship, take the leap. You’ll gain valuable tools and a new way of thinking about how to address environmental challenges. At best, you might discover a new career path and develop a venture that truly makes an impact.
Is there anything else you’d like to share about your experience or your venture?
I’m extremely grateful for the opportunity to participate in the REEF@UD Fellowship. The professors and mentors pushed me to see my potential and inspired me to take that next step, to dive deeper, think bigger, and act boldly for the environment.
Evan is currently pursuing a master’s degree in Environmental Science & Management, with plans to complete it in 2027. Alongside his graduate studies, he’s continuing to refine his business plan, prototype new technologies to support coral restoration, and collaborate with the academic partners and professors who helped shape his journey. It’s a continuation of the same mission that’s guided him from the start: combining science, innovation, and action to protect the world’s oceans.
