Looking for neutrinos, particle physics students find love
Doctoral students married while studying physics together in Madagascar

Doctoral students Miriama Rajaoalisoa and Herilala Razafinime are trying to answer fundamental questions about the origins of the universe in the world’s most sophisticated particle physics laboratories.
Both from Madagascar, they met as undergraduates studying theoretical physics at the University of Antananarivo.
Now married five years, they represent a high-energy physics power couple at the University of Cincinnati.
“We’re not a power couple,” Rajaoalisoa said laughing. “But whenever I get stuck, he helps me.”
“The advantages of being a couple is we are really productive together,” Razafinime said. “If I don’t know how to do something, she does. And if she doesn’t know, then I’ll have some ideas.”
Rajaoalisoa and Razafinime are graduate research assistants at CERN in Geneva, Switzerland and in Fermilab, Illinois, working on the international collaboration Deep Underground Neutrino Experiment.
“I like the challenge of studying neutrinos because they’re so hard to observe,” he said.
Neutrinos are some of the smallest particles in the universe, so tiny they pass through virtually everything by the trillions every second at nearly the speed of light. They are created by nuclear fusion reactions in the sun, radioactive decay in nuclear reactors or the Earth’s crust or in particle accelerator labs, among other sources. As they travel, they often transition between one of three types or “flavors” of neutrinos and back.
Some physicists believe there is a fourth type called a sterile neutrino. The couple are working with physicists around the world on experiments to identify it. The Deep Underground Neutrino Experiment will help physicists study neutrinos and look for new ones.
“Detecting them is very difficult. That’s why we call them ‘ghost particles,’” Rajaoalisoa said. “If we found a fourth type of neutrino, it would turn the Standard Model of Physics on its head.”
Combined, the two have contributed to more than 50 published studies with their international research partners.
While Madagascar isn’t yet well known for its work in high-energy physics, Rajaoalisoa and her husband are hoping to change that. They say their example shows that geography is no obstacle to pursuing your dreams.
“We had a small department of physics in Madagascar,” Razafinime said. “It was just theoretical physics. We didn’t have experimental particle physics. But that’s changing now.”
Madagascar last year hosted the 12th Annual High-Energy Physics International Conference.
“The reason some students in Madagascar aren’t choosing physics is they don’t understand the career paths you can take with a physics degree,” Rajaoalisoa said. “We’d like to show them what you can do with a physics degree.”
Those options span the gamut of top industries along with academia and government research.
Their paths brought them to the physics department in UC’s College of Arts and Sciences.
“UC is a big campus, but the physics department feels quite small,” Rajaoalisoa said. “The professors care about the graduate students. They’re invested in each of our successes. And you really get to understand physics.”
Each year, UC welcomes more than 3,000 students from countries on six continents. Leaving home to study abroad is never easy.
“Home is home. You miss your family. You miss the food,” Razafinime said. “There’s more of a laid-back attitude in Madagascar. There’s a phrase ‘mora mora,’ which means slow down or take it easy. It’s a bit rushed here.”
So what are the odds of two high-energy physicists making a love connection? Since they spent so much time working and studying together, it wasn’t that surprising, they said.
“I felt like she was the kind of girl I was looking for,” Razafinime said. “It was my dream to have someone with the same interests.”
