The Best is Yet to Come: Dr. Ronald Desrosiers’ Breakthrough HIV Research at the Miller School
Dr. Ronald Desrosiers has shaped modern HIV research while mentoring generations of scientists at the University of Miami Miller School of Medicine.
The NBA’s loss is the University of Miami’s and science’s gain.
As a young athlete growing up in New England, Ronald Desrosiers, Ph.D., professor of pathology and laboratory medicine and vice chair of basic research at the University of Miami Miller School of Medicine, once imagined a very different future.
“I have always advised my trainees, when choosing a career path, to follow their instincts, qualified by ‘within reason.’ I wanted to be a professional basketball player,” he said with a smile. “That was not within reason.”
Instead, Dr. Desrosiers followed a path grounded in curiosity, discipline and instinct. In lieu of free throws and bank shots, Dr. Desrosiers reshaped the global understanding of viruses and helped lay the foundation for a potential cure for HIV. In 2026, that journey was recognized with the Outstanding Alumni Award from the Michigan State University College of Natural Science, a fitting honor for a scientist whose influence continues to ripple across generations and disciplines.
Harvard Foundations and the Move to the University of Miami
After a distinguished career at Harvard Medical School and its Primate Research Center, which he chose over an industry position that would have doubled his salary, Dr. Desrosiers could have remained in one of the world’s most established academic circles. But a moment of personal clarity and a bit of marital serendipity shifted his trajectory.
How did Dr. Desrosiers get to Miami? The cold winter winds of Massachusetts blew him there.
“I came home from work one day in the middle of winter, and I walked in the door,” he recalled. “My wife threw her arms up in the air and said, ‘That’s it. I hate winter. We have to move someplace warm.’”
A visit to Florida for a Miami Center for AIDS Research (CFAR) symposium in 2013 led to an offer that aligned perfectly with his next chapter, as well as his wife’s preference to not have to dig their car out of deep snowbanks in January.
“I jokingly told Mario (longtime friend Mario Stevenson, Ph.D.) about my conversation with my wife,” Dr. Desrosiers said. “Three months later, my wife and I were living in Miami, and we’ve been here ever since.”
“The secret to recruiting to Miami is to bring someone down in December, January or February,” said Dr. Stevenson, professor in the Division of Infectious Diseases at the Miller School and Miami CFAR co-director. “It was an easy sale.”
But the decision was about more than the climate. After years of leadership roles, Dr. Desrosiers sought a return to pure scientific inquiry.
“I wanted to step away from administrative duties and focus on science, focus on research, day to day, hour to hour,” he said. “I can spend the vast majority of my time doing research, and that’s important to me.”
Foundational Discoveries That Shaped Modern Virology
That focus has defined a career of extraordinary breadth and impact. From his early work identifying the major methylated nucleoside in messenger RNA to discovering simian immunodeficiency virus (SIV), Dr. Desrosiers’ contributions have shaped modern virology and HIV research.
“Ron has long been one of the most cited scientists in the AIDS field,” Dr. Stevenson said.
Among his many breakthroughs was the identification of critical viral mechanisms, including the role of the nef gene in HIV pathogenesis. The discovery reshaped understanding of how the virus causes disease and opened new avenues for vaccine research.
“His work put us on a path to try and use HIV against itself,” Dr. Stevenson said, “by taking HIV variants that have mutations and using them in a vaccine approach.”
Within a career defined by foundational science, Dr. Desrosiers’ work in Miami evolved into something different. He soon made the transition from understanding disease to potentially eliminating it.
Advancing HIV Cure Research
Recently, Dr. Desrosiers’ work has been pivotal in progressing toward one of medicine’s most elusive goals: curing HIV.
Over the past decade, infectious diseases researchers have been investigating broadly neutralizing antibodies present in a small subset of people who were infected with HIV but didn’t develop the disease. The antibodies recognize most strains of HIV and are potent enough to deter them.
The discovery shifted the field. But the “Why?” behind the “What?” remained elusive.
Building on advances in gene therapy and immunology, Dr. Desrosiers’ lab developed a strategy using adeno-associated virus (AAV) vectors to deliver broadly neutralizing antibodies directly into the body.
The pre-clinical research suggests the approach completely mitigates HIV. Unlike traditional therapies, which require lifelong treatment, the approach turns muscle cells into permanent “factories” producing protective antibodies.
“Those muscle cells produce those potent, broadly neutralizing antibodies for the rest of their lives,” Dr. Desrosiers explained.
“This strategy,” Dr. Stevenson said, “might actually achieve a cure.”
It’s a milestone in the field, and in the career of the man who engineered it.
“This is the first time I’ve had a discovery that’s applicable to human use, that’s applicable for impacting human disease,” he said.
Inspired by Uncle Charlie
Beneath these achievements lies a deeply personal origin story that Dr. Desrosiers himself only fully recognized later in life. His uncle Charlie, who lived with the family when Dr. Desrosiers was growing up, suffered from paralytic polio before advent of the polio vaccine.
“He was the kindest and gentlest human being you could imagine,” Dr. Desrosiers reflected. “He meant the world to me.”
Charlie’s lifelong disability, the result of a disease now largely preventable through vaccination, quietly shaped Dr. Desrosiers’ scientific path.
“Somewhat late in my career, I realized the extent my career decisions were influenced by him,” he said.
That memory now informs his lifelong commitment to science and, to his mind, validates his profession in a time when it’s come under intense scrutiny.
“Without basic science, we wouldn’t be where we are now,” he said.
Mentorship, Leadership and Lasting Scientific Impact
Beyond his research, colleagues emphasize Dr. Desrosiers’ role as a mentor and collaborator.
“I couldn’t want better as a colleague and friend,” Dr. Stevenson said. “He loves science. Every day, he’s either in my office or I’m in his office.”
“Beyond his extraordinary scholarly record, he has been an invaluable asset to the Department of Pathology and Laboratory Medicine through his sustained extramural funding, mentorship of faculty and leadership as vice chair for basic research, markedly strengthening the department’s national and international research profile,” said Merce Jorda, M.D., Ph.D., M.B.A., professor and J.R. Coulter Chair of Pathology and Laboratory Medicine at the Miller School.
His influence extends through generations of scientists trained in his lab.
“My description of a great scientist is someone who trains great scientists,” Dr. Stevenson said. “Some of the most accomplished scientists in the AIDS field were trained by Ron.”
Despite his stature, Dr. Desrosiers remains focused on the work itself and what lies ahead.
“I’m going to be 78 years old in a couple of months. My wife has asked me, ‘Why aren’t you retired?’ But how can I walk away from this?” he said of his current research.
It’s a question that captures the essence of a career still unfolding.
“The best is yet to come,” Dr. Stevenson said.
