On most days, the corner conference room in Building 26 on the Johns Hopkins Applied Physics Laboratory’s Laurel, Maryland, campus is indistinguishable from the many quiet work spaces that surround it. But on a gray afternoon in mid-February, the voices, laughter and energy bounding from its occupants differentiate it from the rest.

As Jamie Porter, Mareena Robinson Snowden, and Ciara Sivels gather around the small table inside, the feeling of stumbling onto a gathering of old friends is difficult to shake. Their bonds, though, are forged less through time than their shared experience of being “the first.”

Each one—Porter, APL’s radiation effects lead for NASA’s Europa Clipper mission; Snowden, a senior engineer in the National Security Analysis Department; and Sivels, a nuclear engineer in the Air and Missile Defense Sector—was the first black woman to earn a Doctor of Philosophy in nuclear engineering from their respective colleges: University of Tennessee, 2012; Massachusetts Institute of Technology, 2018; and University of Michigan, 2018.

Now, Porter, Snowden and Sivels work in three different sectors at APL, dedicating their time and their brains to important challenges facing the nation. Here, they have created a community.

Path to the Ph.D.

“I used to hate physics,” Porter says with a laugh. “Lord, I don’t know how, but now I live in this world.”

Porter arrived in APL’s Space Exploration Sector in 2015. She focuses on radiation hardness assurance for all electric, electrical and electrochemical parts of missions, specifically NASA’s planned Europa Clipper mission to Jupiter’s icy moon. She also manages the sector’s Radiation Analysis and Test section.

Three years before she arrived at APL, Porter was the first black woman to earn a Ph.D. in nuclear engineering from the University of Tennessee. It’s likely, Porter said, that she was just the second black woman in the country to do so, after J’Tia Hart, who received hers from the University of Illinois and subsequently appeared on Season 28 of the CBS show Survivor.

After completing her undergraduate studies, Porter said her goal was to get a master’s. Her professor and graduate advisor, Lawrence Townsend, told her a Ph.D. was what she needed. Porter credited Townsend for pushing her—from undergraduate classes through her doctorate, and even a postdoctoral fellowship. “He told me, ‘You need to do this for yourself, and you need to do this for other people,’” Porter said.

It wasn’t until Porter was nearing her graduation that Tennessee discovered she’d be their first. They didn’t publicize it at the time—a decision reached through a conversation with Porter, where the school admitted embarrassment that it took until 2012 to reach the milestone. They later acknowledged regret at not celebrating it more publicly.

“I actually got to be the speaker at the hooding ceremony the year after I graduated, and it resonated with a lot of people,” Porter said.

When Snowden became the first black woman to earn a nuclear engineering Ph.D. from MIT in 2018, on the contrary, it was well publicized, particularly after her own Instagram post from graduation day went viral. That doesn’t mean her path to that moment was smooth. In retrospect, it wasn’t even a path she necessarily chose.

“People ask me, ‘How did you pick nuclear engineering?’ and I’m like, ‘Nuclear engineering picked me.’ You get a ticket, you get on the train,” she said.

Snowden credited her father, Bill Robinson, with guiding her into studying physics as an undergraduate at Florida A&M University, a historically black college in Tallahassee. It was a visit with a friend of a friend who worked at the school that started her trajectory.

The mantra of FAMU is they don’t expect you to be the best student on the way in, but you will be the best and most competitive student on the way out. That, Snowden said, was absolutely her experience.

It was acceptance into a summer research program at MIT after her freshman year that set Snowden on a firmer course. “It was the only application I sent out because I just knew I was going to be at FAMU doing research in the lab like normal,” she said. “But they messed around and accepted me. And we celebrated like I got into the Ph.D. program.”

A few years later, she did that, too.

Snowden, whose work at APL leverages her technical training in nuclear engineering on current and future national security challenges, applied to eight graduate schools. She got into one.

That’s where she met Sivels.

Sivels and Snowden first connected when the former was an undergraduate MIT student in nuclear engineering and the latter was working toward her Ph.D. That fact alone would knock a 16-year-old Sivels over with a feather.

Originally wanting to be a chef, Sivels’ chemistry teacher pushed her to explore her options—urging her to take his class (advanced placement chemistry) as a senior, recommending she look into chemical engineering schools, and turning her down time after time as she suggested potential colleges that might be a good fit.

“He kept saying, ‘This isn’t good enough, this isn’t good enough,’” Sivels recalled.

To boost her credentials for engineering school, Sivels enrolled in a local community college physics class that covered the history of the discipline. Fascinated by antimatter, she read about work at the California Institute of Technology. The Virginia native showed that school to her mom, who nixed the idea. But as she researched Caltech further, their rival, MIT, popped up.

“I didn’t know what MIT was, the prestige associated with it, anything,” said Sivels, whose work at APL focuses on how radiation interacts with and changes the properties of various types of materials. “It just came up in the sentence with Caltech, so I took it back to my teacher, Robert Harrell, and he was like, ‘Oh yeah, that’s the kind of school you need to be applying to.’”

Even after she was accepted, Sivels was certain she’d be attending Virginia Commonwealth University. It was a campus visit to MIT—coupled with the release of the movie 21—that helped convince her of the school’s esteemed reputation.

Her undergraduate studies were difficult. Sivels noted, among other setbacks, she failed a class and shed many a tear. She got through it, and knew she wanted to further her impact in the field. That’s when her advisors suggested moving on to Michigan for her graduate education.

And it wasn’t until she went searching for a mentor there—preferably another black woman who’d gone through the program—that Michigan noted she’d be the first.

 The Challenges of Being the First

In many ways, these women know they are the exception, not the rule. They were able to navigate turbulent waters and persevere through biases and other challenges.

It doesn’t mean, however, that just because they did it, black women trying to get nuclear engineering Ph.D.s are suddenly no longer the exception.

“I come from an HBCU [Historically Black Colleges and Universities], and so much of that culture and legacy is about that question of responsibility,” Snowden said. “FAMU was intentional about teaching us the context—about what it meant to be black in America and in professional spaces. I went into my Ph.D. process with that context, so when I came up against a challenge, or a person coming at me sideways, I could leverage that context to help me interpret the situation.”

“Both of my parents went to HBCUs, so I had that training, too,” Sivels added. “My parents didn’t want to jade me, but they knew I was smart, and they knew it was coming…When I used to cry to them at MIT, my parents were like, ‘You’ll get over it. Welcome to the world—something is finally hard for you.’”

Porter, who grew up in Tennessee with a white mother and a black father, said, “There are moments when I am like gosh, I do feel the pressure, because I have to deal with comments or expectations that my counterpart does not. Sometimes I will send out an e-mail that says, ‘This is a learning moment, please do not do this [thing you may not think is offensive, but is offensive],’ and I’ll put it out there because I feel like…”

As Porter trails off, Sivels jumps in. “If you don’t, who will?”

“That’s exactly right,” Porter said. “But it’s hard. You have to pick and choose your battles. You have to think, ‘How is this going to affect me if I react right now?’”

“I read a paper once that talked about that,” Snowden said. “They called it the tax. It’s the tax you have to pay of being ‘one of only’ of an identity. That extra calculation you have to do in your mind of ‘How am I going to be perceived in this environment? How do I respond to this stimulus?’ That’s a tax your counterparts from majority populations don’t have to pay.”

And that, the women noted emphatically, doesn’t even include bouts of impostor syndrome that often lurk just around the corner even as they continue their ascents.

Eyes on the Future

To listen to Porter, Snowden and Sivels, you’d think their trailblazing happened with a shrug of the shoulders—they just put their heads down and did what they thought they were supposed to do. It wasn’t nearly so simple.

They also know the rewards of their perseverance come with a duty to future generations.

“I definitely feel a responsibility,” Porter said. “I am the lead radiation engineer for a billion-dollar flagship NASA mission, and when I do reviews, most often I am the only black person in the room. So, I try really hard to bring people with me.”

They make an effort to mentor those behind them. They work on committees and in outreach programs, like the IF/THEN Ambassador program, of which Sivels is a part.

And they tell their stories. They talk about their journeys so that their shared experiences as “the first” are ultimately just a way to pave the road for those behind them.

“I look at the diversity and inclusion conversation as two sides to one coin,” Snowden said. “You have the recruitment piece, and the second, less-talked-about part, is the retention piece. Once they’ve gotten into these programs, and they’ve gotten their Ph.D.s and they’re STEM professionals, how do we get them to and through mid-career, promoted up to senior levels, given power so they can hire, and all of those types of things that will make an impact?

“Now, I think the mission is to preserve the recruitment momentum but create a new body of momentum on the retention piece, but it’s the harder challenge to me.”

In a way, what Porter, Snowden and Sivels would like is for their accomplishments as “the firsts” to fade. For them to be the firsts of many—and for that to extend through to professional life.

“I love outreach,” Porter said. “It’s telling your story. It’s letting a little girl see what’s possible. [Snowden and Sivels] saw each other [at MIT], but they didn’t really see it was possible until it happened. I didn’t see anybody and it was just like, ‘Well, this is happening.’

“But it all goes back to that responsibility and the fact that now we have that responsibility to put ourselves out there—so other girls can see it’s possible.”
