Why study this degree at Mines?
Energy systems are becoming more complex, more connected and more consequential. Power generation and delivery, industrial energy use, fuels, storage, buildings and transportation are increasingly designed as one integrated system that has to be reliable, affordable and ready for rapid technological change. That reality is pushing employers to look for people who can do more than “run the model.” They need leaders who can frame the right questions, quantify tradeoffs, validate results with real data and translate technical findings into decisions.
A Doctor of Philosophy in Advanced Energy Systems from Colorado School of Mines helps you build that kind of influence. You will learn how to evaluate entire energy pathways from first principles to system performance, then back your conclusions with rigorous research. Because this program is built to be interdisciplinary, you will work across fields like mechanical engineering, applied physics, data analytics and power systems, depending on your research direction. You will also benefit from the program’s close connection with the National Laboratory of the Rockies (NLR), giving you exposure to problems and tools that show up in real projects and real deadlines while working alongside NLR researchers on collaborative projects.
If you want a doctorate that stays grounded in engineering practice while still pushing research boundaries (in the normal, non-buzzword sense), this program is designed for you.
Program Overview
The Advanced Energy Systems PhD is an interdisciplinary, on-campus doctoral program that prepares you to lead original research on the technologies and decisions shaping modern energy systems. Developed in collaboration with NLR, the program conencts the depth of university research with the scale and complexity of national laboratory challenges.
As you progress, you move beyond applying existing tools to developing and validating new approaches. You will learn to model and analyze energy conversion systems, optimize designs and operations within real-world constraints and use data and experimentation to test assumptions and refine models. You will also build the ability to communicate complex technical findings clearly to both technical and non-technical audiences—an essential skill for advancing solutions in today's energy landscape.
What you’ll study and do
This is a research-driven PhD with coursework that supports your dissertation work. The program requires a minimum of 72 credit hours, typically split between 36 credits of coursework and 36 credits of research. You will complete core PhD-level courses plus advanced electives tailored to your research plan.
A distinctive part of the experience is the program’s connection to NLR. The program has been described as including two 12-week rotations at NLR, giving you a structured way to learn lab methods, collaborate with researchers and connect your dissertation to active projects.
You and Mines PhD: A Right Fit?
You will likely thrive in this program if you:
- Enjoy messy, real-world problems where the “right” answer depends on constraints and tradeoffs
- Can move between details (models, data, experiments) and the big picture (system behavior, decisions)
- Are comfortable working across disciplines and learning what you need as your research evolves
Key Program Research Areas:
- Energy generation technologies
- Grid modernization

World-Class Labs, Centers and Facilities
The National Laboratory of the Rockies (NLR) is the U.S. Department of Energy's primary national laboratory for energy systems and Mines’ partner in the Advanced Energy Systems Graduate Program. Located down the road from the Mines campus in Golden, NLR bridges foundational research with practical applications to integrate various energy sources, storage, buildings, transportation, and emerging technologies.
The Colorado Fuel Cell Center develops electrochemical devices to address our nation’s needs in electricity generation and energy storage. Batteries, fuel cells, electrolyzers and membrane reactors are all active topics of research and development for the center, led by Professor Neal Sullivan.
The Advanced Multiscale Building Energy Research (AMBER) Group applies interdisciplinary building science to address daily challenges faced by local and global communities. Led by Associate Professor Paulo Cesar Tabares Velasco, the group focuses on issues that directly impact people, including neighborhood-scale electrification and building retrofits, thermal comfort and indoor air quality, building envelopes, and thermal energy storage.

Frequently Asked Questions
Why is a PhD in Advanced Energy Systems beneficial?
A PhD is useful when you want to do more than apply existing methods. In Advanced Energy Systems, the hardest problems are often about system interactions, uncertainty and tradeoffs. A doctorate trains you to define a research question, build or adapt the right methods, validate results and defend your conclusions. In this program, that training is paired with interdisciplinary collaboration and a strong connection to NLR so your research stays tied to real systems and real constraints.
What are the most important technologies shaping PhD-level research in energy systems right now?
You will see rapid change in how power systems are planned and operated, how storage is integrated, how industrial processes are modernized and how data is used to predict performance and reliability. PhD-level work often focuses on questions such as what improves efficiency at scale, what improves resilience, what reduces cost over a system lifetime and what can be verified with data. Your dissertation will typically focus on one slice of that landscape, but you will learn to connect your results back to system behavior.
How does the Mines and NLR connection show up in the PhD experience?
The program is designed in collaboration with NLR and has highlighted structured rotations at NLR as a core feature. That can change your day-to-day research—you can collaborate directly with national-lab researchers, learn tools used in high-impact projects and build relationships and networks that carry into your career.
What can you do career-wise with a PhD in Advanced Energy Systems?
Common outcomes include:
- Research and development roles in energy technology and advanced manufacturing
- Systems engineering and optimization roles in utilities, grid technology companies and industrial firms
- National laboratory research positions
- Faculty or research scientist paths in academia
- Technical leadership roles that bridge engineering, strategy and decision-making
Is this program a fit if my background is not mechanical engineering?
Often, yes. Advanced Energy Systems is interdisciplinary by design and is intended to pull from multiple technical backgrounds, as long as you have strong fundamentals and you are ready to build what you need for your research direction. Your coursework and research plan can be tailored to close gaps, deepen your strengths and support your dissertation topic.
My Ph.D. program had a partnership with the National Laboratory of the Rockies (NLR). For four years, I did all of the research for my thesis with the residential buildings group at NREL. In this time, I was constantly learning on the job while at the same time building a professional network. When my group manager learned that I was starting to apply for jobs in the semester before I defended my thesis, he pulled me aside and asked, almost sadly, why I wanted to leave. I told him I didn't and a couple weeks later I was interviewing for a full-time position in the group.
