What was your first job, and what did it teach you? In high school in Dhaka, I tutored middle school students to support myself and my brother. It taught me discipline, responsibility, and the value of passing knowledge forward. I also discovered that the best way to learn is to teach, something that’s helped me at every stage of my career.
Who has been your greatest influence? Many mentors have shaped my life, but I’ve always drawn inspiration from innovators like Steve Jobs, James Dyson, and Sony founder Akio Morita. They remind me that product development—whether it’s a phone, a vacuum, or a nuclear reactor—takes the same ingredients: grit, curiosity, and a relentless desire to build something wonderful for the world.
If you had a theme song, what would it be? “Cornfield Chase” by Hans Zimmer (from the Interstellar soundtrack). I gravitate toward instrumental music. It helps me quiet my mind and find balance before tackling complex problems.
What’s the best career advice you have received? My first mentor at Westinghouse, Ed Lahoda, told me, “Don’t fall in love with your creations.” As engineers, when we become too attached, we try to force them into the world even if they don’t belong. The real discipline is knowing when to let go and move on to build what the world truly needs.
What’s on your bucket list? Achieve criticality by July 4, 2026; build a factory that produces 100-plus reactors a year and then replicate it around the world; be the best father I can be to my soon-to-arrive son; one day, see Earth from space.

What did you want to be when you were younger?
I dreamed of being a famous singer as a kid. When I decided to go with a more practical career, I thought about doing something in medicine. My mom was a pharmacist, so I grew up learning about different medical topics, and practicing medicine seemed like fun puzzles that helped people feel better.
When you reflect on your career so far, which achievement stands out most? For the last few years I’ve been volunteering with the Illinois High School Science Bowl. Two students who have been participating for a few years have decided that they want to study nuclear engineering in college (at one of my alma maters!) because they’ve been able to meet me and learn about nuclear energy and nuclear engineering. Knowing that what I do impacts the next generation in a positive way is the greatest achievement I can have.
What is your secret talent? I do a lot of crafting, mostly crocheting and knitting.
What is a long-term career or personal goal? I started out my Ph.D. under Katy Huff at the University of Illinois. For the past few years, I’ve been saying that I want to be like her when I grow up: working on fuel cycle modeling, developing software, working with students, and teaching others.
Who has been your greatest influence? Prof. Jamie Coble got me involved in research when I was an undergraduate student, which helped me discover that I wanted to go to grad school and have a career in research. Those opportunities taught me a lot of technical content and skills and also helped me learn other things, like when you’re a little scared of what’s in front of you then you’re probably going in the right direction.
What is the top song on repeat on your Spotify right now? I really enjoy musical theater, with “Defying Gravity” and “For Good” from Wicked as personal favorites.
Fabiola Cappia
Age: 37
Title: Fuels postirradiation examinations division director, Idaho National Laboratory
Hometown: Orino, Varese, Italy
Cappia describes herself as just a “small-town woman with a passion for nuclear fuels now leading the largest inert hot cell in the U.S.” She leads a team of nearly 80 technicians, researchers, and engineers at INL’s Hot Fuel Examination Facility. Her leadership in the DOE’s Accident Tolerant Fuel program and high burnup fuel research has addressed critical data gaps and strengthened the U.S. nuclear fleet.
What did you want to be when you were younger? Many things. First an archeologist, then a doctor, but I have always loved math and physics, so engineering was the natural choice.
When did you first “discover nuclear”? I grew up with it—my village is very close to a research center for the European Commission, the JRC in Ispra—which had a research reactor. In high school, I visited Politecnico di Milano and saw a presentation about a major in nuclear engineering, and I knew that was my path. When you reflect on your career so far, which achievement stands out most? A couple, I would say. I had a pretty sharp transition from postdoc to staff and was put in charge of the entire Accident Tolerant Fuel postirradiation planning and execution. I more than doubled the business volume that came in to INL in that area. Later, I led the team that prepared HFEF to receive and conduct PIE on the LWR commercial fuel that we received in December 2023. It was not an easy task as we had not been doing that kind of work since 2005(ish), so the know-how had to be rebuilt.
What is a long-term career or personal goal? I want to see new nuclear become successful, and my long-term career goal is that one day it will be said that it was not possible without the contribution and technical expertise of my team at the Hot Fuel Examination Facility.
What is your secret talent that few people know? I am a good cook and an excellent baker, particularly patisserie-type baking.
Who is your personal MVP? My partner, Dr. Tsveti Pavlov, who is also a scientist at INL. He leads the thermophysical property group at the INL’s Materials and Fuels Complex.
What was your first job, and what did it teach you? I picked blueberries at a farm for a summer when I was 12, and that taught me that it is hard to earn money, and you should not waste it. When I was 16 years old, I got a waitressing job in a restaurant and had a sales assistant job at the same time to help in the household with bills and expenses. That experience was humbling, but we had a good crew in both places, and I had a lot of fun. Those experiences taught me the importance of having a good working environment and a few lessons about successful customer services that have been handy throughout my career.
What is your favorite food or restaurant? My heart remains at home, in Italy. Whenever I go back home, my family and I go to a restaurant on the lake that specializes in seafood; I miss that the most.
What’s on your bucket list? I really want to climb all nine of the Idaho 12ers. I started with Borah Peak a couple of years ago and then I had a back injury. I hope to heal completely soon and resume my endeavor.

Carasik is also a dedicated mentor and advocate for parity in STEM and is a co-founder of ANS Cares.
When you reflect on your career so far, which achievement stands out most? This is a very hard question because I have both my personal achievements and those of my students. My students’ achievements would have to be my first three earning their Ph.D.s (Arturo, Connor, and Vulcanoff). My personal achievement is my DOE Early Career Research Award under Fusion Energy Sciences.
What is a long-term career or personal goal? Right now, my long-term career goal is having a large enough career impact to become a NASEM member. To me, this means I’ve made a lasting positive impact on the students and early-career researchers.
What is your secret talent that few people know? I was really good at Texas Hold’em at one point.
What’s the best career advice you have received? Split between these two: (1) Dr. Eric Loewen (an ANS past president) recommended I try to intern at a utility, a reactor vendor, a national laboratory, and the NRC. I got three of the four and I learned a lot of what I wanted to do. (2) “Follow things to their logical conclusion” was extremely important advice, as I’ve gone through the junior/early-career part of my life.
What’s on your bucket list? A long beach vacation on one of the Caribbean islands.

What did you want to be when you were younger? When I was in kindergarten, I couldn’t decide whether being an astronaut or a welder was cooler, so I decided that I would be a “space welder.”
When did you first “discover nuclear”? In 11th grade, I had to pick a topic and prepare a debate. I chose to argue that nuclear energy is dangerous, but as I started researching the track record of nuclear power, I actually reversed course and ended up delivering a passionate argument for the safety and public health benefits of nuclear.
When you reflect on your career so far, which achievement stands out most? It’s been really fulfilling to see the adoption of the regulatory modernization methodologies and approaches that I’ve played various roles in developing and getting endorsed to enable their use. For example, both of the construction permit applications for the two different ARDP efforts implement the LMP and TICAP approaches—which I have been either supporting or leading since working on my graduate degrees.
What is your favorite food or restaurant? I love In-N-Out Burger—a controversial opinion in Texas.
What is a long-term career or personal goal? I’d really like to see a liquid-fueled reactor design (e.g., a molten salt reactor) get licensed and operate. Bonus points if it’s MCRE, the Molten Chloride Reactor Experiment (which I have worked on since its inception) and/or it implements the liquid fuel performance characterization approach that I have helped develop (as part of an EPRI project).
Who is your greatest influence or personal MVP? It’s impossible to pick just one greatest influence and/or MVP. My top 4 (in the order I met them) would be my mom, my brother, my wife, and my daughter.
What is the top song on repeat on your Spotify right now? My daughter is one-and-a-half, so all my top songs are from Ms. Rachel. “I’m So Happy” is probably the current #1, but it always depends on the day.
What’s on your bucket list? One day I’d like to teach science at a high school or community college. It’d be really awesome to know that I had been able to inspire and/or support at least one person in becoming interested and motivated to work towards making the world a better place for everyone, especially through science/technology.
