In a time marked by turbulence and intricate challenge, few have helped to light the way from difficulty to possibility as much as Professor Richard C. Larson. Popular around the world as “Doctor Queue,” Larson’s professional journey at MIT and beyond has served as a witness to the transformative power of inquiry, persistence, and the ongoing human urge to make a positive impact.
Early Life: Origins of Curiosity and Autonomy
Richard Larson’s journey starts in Bayside, Queens, New York, in 1943. His early years, though, played out against the backdrop of various American landscapes, each contributing to his worldview and personality. When Larson was five, his family relocated to Sunbury, Pennsylvania-a small, rural farming town. There, set amidst open fields and woodlands, Larson learned the importance of exploring and being independent for the first time.
A pivotal experience in his youth says a lot about how he grew up and what values were imparted by his parents. When he came of age for kindergarten, his parents gave him a choice: go to kindergarten or stay at home another year. “I thought that was pretty cool,” he remembered. Following a weekend of consideration, young Larson decided to stay a child for another year, playing outside and learning from the world around him. When he finally enrolled in first grade, he lagged behind his peers, unable to count to ten or sign his name. But with typical resolve, he soon caught up-a harbinger of the persistence and flexibility that would characterize his subsequent career.
The Spark of Science: Falling in Love with Learning
Richard Larson’s interest in math and the physical sciences began early and intensified each year. At Needham High School, outside Boston, he was one of the first to enroll in MIT’s new PSSE physics course, a byproduct of the post-Sputnik era’s emphasis on scientific achievement. This mathematics-infused course, which connected math with the physical world, revolutionized Larson’s learning. “I sort of fell in love with that way of learning, and of research, and of science,” he said.
This experience did not only solidify his love for science, but also place MIT on his radar as a destination where those passions could be pursued at their highest level. By his fourth year, MIT was his “stretch school”-something he hoped to aim for, but never thought that he would ever actually get there.
MIT: Finding Belongingness in a World of Possibility
Richard Larson’s acceptance to MIT was exciting and daunting. As with many outstanding students, he at first assumed that his invitation was an error. The cultural diversity and academic excellence of the students around him-from Argentina, Austria, Italy, Cuba, Iowa, and California-was inspiring and, at times, humbling. But as he became immersed in MIT’s cooperative culture of analytical intensity, he found his niche.
“When you work hard, and you earn competitive grades, and your peers accept you as a supporting colleague, you know you belong,” he said. He decided to major in Electrical Engineering (Course 6), motivated by both family tradition-his father was an electrical engineer-and the field’s reputation for developing systematic, quantitative thinking. “If you don’t know what you’re going to do, but you want to bring systematic reasoning, quantitative reasoning, to bear on the world, the default choice here on campus has been, and remains, I think, Course 6, Electrical Engineering and now Computer Science. Because it conditions your mind to think systematically about hard problems in ways which are very useful, regardless of what you do later,” Larson said.
The Accidental PhD: Seizing Opportunity
Richard Larson’s course to graduate studies at MIT was, according to his own self-description, unplanned. Brought into MIT on a Master’s degree invitation through a fellowship from Bell Laboratories, he was urged on by mentors to follow through on earning a PhD. In spite of his own feelings that he wasn’t “doctoral material,” he was badgered-frequently at great length-by teachers and peers into preparing for and sitting the qualifying exams.
Paying them left the way to Ph.D. study, one which he didn’t expect but to which he would be outstandingly well-adjusted.
A turning point came during his MIT residency, when an theft in his residential group got him interested in examining police investigation practices. Browsing through titles, he found himself borrowing an entire pile of detective novels in the library which became noticed by his advisor Professor Al Drake. Seeing the potential for academic research, Drake urged Larson to make this a formal area of study. This resulted in his master’s and doctoral theses on policing, his first book (Urban Police Patrol Analysis), and even a position as the youngest member of the Science and Technology Task Force of the President’s Crime Commission.
From Student to Faculty: Finding a Voice
Becoming a faculty member at MIT was its own challenge. “You glance around, you see all these Nobel laureates, and members of the National Academy of Sciences and Engineering, you say, why am I here?” Larson confesses. But as he sat down to write, do research, and work with students, he came into his own. “You begin receiving research funding, and all of a sudden you feel you are in,” he adds. Larson’s humility and humor-he compares his early imposter syndrome to a Groucho Marx routine-have won him over colleagues and students alike. Over time, he has become not only a respected scholar, but a beloved mentor and leader.
Teaching at MIT: A Laboratory of Ideas
Larson’s teaching style is marked by experimentation, activity, and a fundamental respect for his students. “The greatest asset of MIT is our students,” he declares. “They’re very, very smart, they’re very, very energetic, and you can experiment with them. Provided you challenge them and keep them engaged, they always return more than you give to them.” He has instructed everything from large undergraduate lectures in applied probability-sometimes with more than 350 students-to small graduate seminars and freshman seminars with only eight students. He enjoys the various dynamics each environment presents, from the challenge of motivating a large lecture hall to the pleasure of rich discussion in smaller groups.
As a thesis advisor, Larson has supervised countless master’s and doctoral students, whom he regards as his ‘academic children.’ Several of them have become professors in their own right, resulting in a scholarship genealogy that has expanded to include ‘grandchildren’ and ‘great-grandchildren.’ Larson counts the legacy of mentorship among his most cherished achievements.
Operations Research: The World’s Most Important Invisible Profession
Richard Larson is a self-described “OR enthusiast.” He likes to tease about the misunderstanding of the term-people think it has to do with medical operating rooms. In fact, OR is the study of decision-making in complicated systems, combining industrial engineering, management science, and applied mathematics. “I like to refer to it as the physics of the real world that includes people and technology,” he says.
His initial work in optimizing police patrols and emergency service systems was establishing new benchmarks for the industry. Gradually, he widened his research to cover a broad array of service systems, such as healthcare, disaster management, manpower planning, and dynamic pricing of key infrastructures.
Richard Larson’s work in queueing theory, specifically, earned him the moniker “Doctor Queue.” Not only did he create new computational methods, but he also investigated the psychological and experiential dimensions of waiting, so his work is applicable to both scholars and practitioners. His work has been extensively reported in the media, demonstrating its wide-ranging impact on society.
Innovations in Queueing Theory and Service Systems
Richard Larson’s contributions to queueing theory have been especially far-reaching. He created the Queue Inference Engine, a computer program that can estimate queueing parameters from sparse data-a breakthrough with implications across the spectrum from telecommunications to healthcare. His Hypercube Queueing Model is a widely referenced standard and has become the go-to tool for analyzing emergency service systems.
In addition to the math, Larson has probed the psychology of waiting, seeing that judgments about fairness, openness, and communication can significantly impact people’s experiences. His work has been embraced by hospitals as well as amusement parks, indicating the applied significance of his studies.
Larson’s work has also translated to disaster planning, where he has simulated evacuation plans and emergency response supply chains, and public health, where his research into disease dynamics and vaccine distribution has been used to inform policy and practice.
