Hillary Hagen-Peter is a Senior Engineering Geologist at Atlas, currently working on Oklo Inc.’s Aurora powerhouse project at Idaho National Laboratory near Idaho Falls. As fieldwork lead and now project manager, Hillary is helping assess and prepare this Aurora powerhouse site, which supports advanced reactor technology designed to deliver low to near‑zero emission energy. Hillary explains how geoscience bridges the environmental challenges of past energy practices with the sustainable, low‑carbon solutions needed for the future.

“I am deeply passionate about my work on the Oklo Aurora powerhouse project and other advanced nuclear initiatives that are opening doors to a cleaner energy future. With today’s��ability to recycle and reuse spent fuel through advanced nuclear technologies, I see this work as a vital bridge between the environmental impacts of past energy practices and the sustainable, low‑carbon solutions we need moving forward.” –Hillary Hagen-Peter

My path into geology began long before my professional career. I was inspired by my older brother, whose undergraduate and graduate fieldwork took him from Mongolia and Italy all the way to Antarctica. Hearing his stories about working in remote, rugged places sparked my curiosity about a field that blends science, exploration and global travel. I signed up for an introductory geology course soon after and was immediately hooked. The combination of fieldwork, problem‑solving and understanding how the Earth shapes our infrastructure and communities set me on the path I’m on today.

So far, my work as a geologist has taken me across the Pacific Northwest, where I’ve led complex geotechnical and geohazard evaluation programs for nuclear and technology infrastructure projects throughout the United States and Canada. Whether hiking through steep terrain, flying by helicopter to remote sites or working in extreme weather, including temperatures dropping to –40°F (the rare point where Fahrenheit and Celsius finally agree), each location brings its own challenges and a distinct set of potential geohazards.

At Atlas, I’ve managed large scale geotechnical programs involving comprehensive hazard assessments. One of the most meaningful has been leading geotechnical work for the Oklo Aurora powerhouse project at the Idaho National Laboratory in Idaho Falls. This project is advancing a more resilient and sustainable energy future, and I’m proud to contribute to efforts that support the broader transition to clean, reliable nuclear energy.

On this project, I started out as a Fieldwork Lead for subsurface drilling and geophysical investigations before moving into full project management, overseeing drilling operations, laboratory testing and final reporting, all in compliance with the American Society of Mechanical Engineers Nuclear Quality Assurance (ASME NQA1) requirements. This work is meticulous and often challenging, but it is foundational to building safe, sustainable infrastructure.

Through both my studies and field experience, I have seen how geoscience directly shapes the success of advanced nuclear projects, helping see that innovative clean‑energy technologies are built on safe and resilient ground. From evaluating hazards such as flooding, expansive and collapsible soils, landslides, faulting, seismicity and volcanic activity, to leading subsurface drilling and geophysical investigations, geoscientists provide the critical data that informs design, safety and long‑term performance.

I’m especially inspired by the nuclear sector’s ability to recycle and reuse spent fuel through advanced nuclear technologies. This capability represents a vital bridge: connecting the environmental impacts of past energy practices with the low‑carbon solutions we need moving forward. When paired with renewable sources like solar and wind, advanced nuclear energy becomes part of a resilient, diversified path toward achieving the United Nation’s global goal of net‑zero carbon emissions by 2050.

Across all of these efforts, I am reminded that sustainable energy isn’t just a technological challenge; it’s a geotechnical one. The future we build must stand on solid ground, and I’m proud to help ensure that the next generation of clean‑energy infrastructure is resilient, responsible and built to support communities for decades to come.

Engineering for Impact: Leadership, Innovation and the Future of Infrastructure

Atlas’ Sector Lead & Director of Operations – New York & New Jersey, Angel Cambero, P.E., MSI shares how his parents inspired him to become an engineer and how he finds meaning in serving his community through his engineering profession.

For me, engineering has always been more than a profession—it’s a legacy. Growing up with two civil-engineer parents, I learned early how ideas on paper become real structures that shape people’s daily lives. That exposure gave me a deep respect for the discipline and ultimately guided me toward a career where creativity, logic and community impact intersect.

Today, in my role leading operations across the New York and New Jersey regions at Atlas, I still approach challenges the way I did as a young engineer: with curiosity, precision and a commitment to quality. While my focus now spans strategy, financial performance and team leadership, the engineer in me remains central. A technical mindset enables better decisions, supports our project teams and ensures that quality isn’t a goal—it’s a standard.

One of the most meaningful projects I’ve led is our work at the South Brooklyn Marine Terminal. This project is part of a multi‑billion-dollar investment in renewable energy and represents exactly where the industry is headed. Our team oversaw the special inspections and materials testing across a 73‑acre offshore wind hub, ensuring structural integrity and safety for infrastructure that will power New York’s clean energy future. It was a reminder that engineering isn’t just about building structures; it’s about building progress.

Technology is accelerating that progress at an unprecedented pace. Tasks that once required days of manual calculations can now be completed in minutes from a mobile device. Digital reporting, real‑time data tools and advanced testing equipment are transforming how we deliver projects, enabling greater accuracy and faster, more informed decision‑making. As these tools evolve, engineers will spend less time processing information and more time interpreting it—shaping outcomes instead of reacting to them.

Yet despite the rapid pace of innovation, the fundamentals remain unchanged. Field experience, humility and collaboration continue to define exceptional engineers. My advice to aspiring engineers is simple: stay curious, ask questions and embrace every opportunity to learn. The field will teach you as much as the classroom ever will, and each role—no matter how small—gives you a new lens through which to understand the built world.

At Atlas, engineers play a vital role in ensuring public safety and the resilience of our infrastructure. Whether through inspections, materials testing or technical guidance, our work directly affects the communities we serve. That responsibility is both grounding and motivating. It reminds us that engineering will always matter, no matter how much technology evolves.

A century ago, the challenges were different, but the mission was the same: build safely, wisely and for the future. This Engineers Week, I’m proud of the work Atlas is doing to help transform the future and enable our communities to flourish and thrive. As we look ahead, I’m excited to help shape what the next century of engineering will look like—and to support the next generation of engineers who will carry that mission forward.
