Researcher Spotlight: Susan Habas’ Journey to Catalytic Innovation at NREL
From Sci-Fi Dreams to Scientific Discovery
Susan Habas, now a senior scientist and distinguished member of research staff in the National Renewable Energy Laboratory's (NREL's) Catalytic Carbon Transformation and Scale-Up Center, had an unconventional start to her career in chemistry.
Her research focuses on developing innovative catalysts for selective transformations of carbon sources into fuels and chemicals. She is a principal investigator in the Chemical Catalysis for Bioenergy Consortium, where she leads a multinational laboratory effort to advance new synthesis approaches and operando characterization capabilities for catalytic systems.
"In high school, I thought I wanted to become a ‘biomedical genetic engineer.’ I had no idea what that meant (and I’m fairly sure it’s not a thing), but it was the '90s, and there was so much compelling science out in the world—Michael Crichton’s 'Jurassic Park' and 'ER,' 'The Hot Zone' by Richard Preston, and advances in DNA analysis in forensics, as just a few examples," she recalled. "For someone interested in science, the career options were exciting but overwhelming."
A freshman seminar at Wheaton College, titled "Science in Society," intensified her love for sci-fi books—cyberpunk via Neal Stephenson in particular—but did not get her closer to choosing a career path. Habas majored in biology, thinking she might go to medical school, but classes in molecular biology and a summer program at The Jackson Laboratory working with mouse models for genetic research led her toward biochemistry.
Encouragement from her chemistry professors helped her land a summer program in lanthanide and actinide chemistry at Los Alamos National Laboratory, solidifying her growing interest in chemistry and the national laboratory research environment.
Finding Focus in Advanced Energy
Habas' journey to advanced energy R&D was not linear. Before completing her Ph.D. in chemistry at the University of California, Berkeley, she spent a year and a half as a Fulbright Scholar at Massey University in New Zealand working on carbon nanotube-based materials.
Returning to the United States, Habas explored photoactive nanocrystals at Lawrence Berkeley National Laboratory.
"At this point, I felt like I had finally found a reasonably focused career goal, at the intersection of materials chemistry and energy applications," she shared.
Curious about how fundamental discoveries transition to real-world applications, she found NREL to be a perfect fit for a postdoctoral position, where she could continue materials chemistry work while learning about photovoltaics and industry-scale challenges.
Innovating With Catalysis and Plasma Science
Today, Habas' research focuses on developing tailored catalysts for a variety of chemical conversions targeted at fuels and chemicals production. One particularly exciting area is plasma catalysis, where applying an electrical potential to a gas can activate stable molecules like carbon dioxide and methane at low temperatures.
"The excited species of the plasma can then react with one another to form higher-value products including long-chain hydrocarbon fuels and structured carbon materials," Habas explained. "Another promising application is the use of plasmas at gas-liquid interfaces to precipitate and recover, ideally selectively, critical metals from dilute wastewater sources."
Habas also serves on the editorial board of EES Catalysis as an associate editor and is on the advisory board of Sustainable Energy & Fuels, contributing her expertise to help guide the future of catalytic research.
"It has been an exciting (and challenging!) area of research to get involved in," she added, "and it has been fantastic to work with and learn from incredibly talented early-career researchers with plasma expertise and to discover related programs and experts already at NREL."
The Joy of Lifelong Learning
For Habas, the most rewarding aspect of her work is the constant evolution of science and her own learning journey.
"The best part of my job, which is also emblematic of my career path, is learning about new science. And the best part about science is how it keeps advancing and how your career path can move with it," she said. "I appreciate that NREL has enabled me to keep learning and branching into new areas of research and that there are great people here who are willing to help me learn and who share this enthusiasm."
