Roland Pellenq’s office is both tidy and cluttered. It’s built around the centerpiece of a stack of papers and manilla folders that sits one foot high on a corner of his desk, right next to his Mac desktop. On the windowsill is a variety of interesting trinkets—a mug, an hourglass filled with black sand, a replica of what looks to be a fanciful tower of some kind—and opposite the small, round table I sit at is a wall of books. The organized chaos reminds me of someone who makes a mess when working and then cleans up before they leave, enacting the process so consistently and repetitively that they end up with a perfectly efficient system.
On paper, Dr. Pellenq is an accomplished academic. Beyond a Master of Science from Marseilles in France and a doctorate from London, he is the director of the CNRS branch at MIT—a joint lab effort that links MIT to Marseilles, where they study complex porous materials. He’s also one of the founders and leading researchers at MIT’s Concrete Sustainability Hub (“Not cement,” he interjects quickly ), but he assures you right away that he isn’t the only one, and he’s happy to talk about the people who work for him or who have helped him in his career. He’s published several papers over the years, some under the auspices of industry giants like Shell, and, although modest, he enjoys pointing out how his research has led him to meet some of the top leaders in the gas and cement industry.
Such is the man who greets me outside of his office. I had knocked on his door and hadn’t gotten an answer, but Pellenq emerged minutes later from the office just next door to his, apologizing for not realizing I was there. He’s dressed in jeans and a gray sweater, with a blue scarf wrapped loosely around his neck, and he balances the hanger holding his suit jacket on bookshelf before he ushers me to a seat.
“The reason I’m here is kind of random,” he tells me with a laugh as he eases into his office chair. He pauses to consider this. Then: “Well, not random. What happened is that I work for CNRS. Do you know what that is?”
As happens with most of the questions he asks me, Pellenq gives me no chance to respond before launching into an answer: CNRS is the largest governmental research agency in France—“probably the biggest one, actually,” Pellenq adds—and he is one of its most productive members. (In fact he was Director of Research there from 2002 to 2007.) It’s clear that this is a man who loves his work and loves explaining to others what he does, and it takes very little prodding for him to jump on a new story or explain another process. I barely even ask how he ended up at MIT before he launches into the tale of working with a fellow MIT civil engineering professor, Franz-Josef Ulm, when he first arrived in the States.
“We were still smokers back then,” he says with a laugh, as if that has everything to do with the story. He tells me how the CNRS approved his visit to the US and sent him on his way, and how he bridged the gap between MIT and CNRS to create a joint lab. I press him for details, and it’s hard to hold back a laugh at his earnestness when he says, “I sent a text message congratulating Alain for the new job, blah blah blah blah. And then I say, ‘What, by the way, why don’t you come to MIT,’ and he said, ‘Yes, okay, alright, okay,’”—as though texting Alain Fuchs, then acting president of CNRS, was no big deal.
But for Pellenq, it isn’t a big deal. His relationship with his home country and the people there is one of fondness and familiarity, though after eleven years of living here he’s very comfortable with his situation in the United States. Perhaps a little too comfortable, even—at one point he says excitedly, “What we have,” only to stop and correct himself by saying, “Or rather, what you have,” before going on to explain that while at MIT he has plentiful resources, it’s in Marseilles where some of the really snazzy tech work like three-dimensional imaging takes place.
Pellenq’s openness isn’t limited to the candor with which he speaks of his own work and life. At the end of the interview, he pelts me with questions about my interests and majors and plans for the summer, suggesting several places that I might find good to work at and encouraging me to apply. I laugh and thank him as I leave his office. Then I recall that we hadn’t shaken hands or even introduced ourselves. He had simply checked that I was who I said I was before he settled in to speak. Clearly, the niceties of formal introductions are, for him, unnecessary.
