At an age when most teenagers are still navigating secondary school, choosing subjects, and beginning to wonder what they might study at university, Laurent Simons had already reached an academic milestone that normally takes decades to achieve.
At just 15 years old, the Belgian-Dutch prodigy successfully defended a doctoral thesis in physics at the University of Antwerp.
On November 17, 2025, Simons presented his doctoral research, titled Bose Polarons in Superfluids and Supersolids, at the university's Campus Drie Eiken. His supervisors were professors Jacques Tempere and Michiel Wouters of the Department of Physics.
The University of Antwerp officially lists the defence, making one of the most extraordinary chapters of Simons' accelerated education a matter of academic record.
Yet focusing only on his age risks missing the more interesting part of his story.
For Laurent, earning a doctorate was never supposed to be the final destination.
It was another step toward a much larger ambition: combining different areas of science in an attempt to understand human biology, slow ageing, extend healthy life, and perhaps one day challenge the biological limits of the human lifespan.
It is an enormous ambition, and one that remains far beyond what contemporary science can promise. But Laurent has been moving toward it for years.
An Extraordinary Academic Journey
Long before his doctorate, Laurent Simons was attracting international attention because of the unusual speed at which he progressed through school.
He completed secondary education when he was only eight years old.
He later studied physics at the University of Antwerp, where he completed the standard three-year bachelor's curriculum in roughly 18 months.
By the time he was around 11, he had earned his bachelor's degree in physics.
His academic trajectory was already so unusual that universities and research institutions across Europe began paying attention.
In January 2022, the Max Planck Institute of Quantum Optics in Germany published an article about Laurent after he joined researchers at the institute and Ludwig Maximilian University of Munich for an internship.
The institute described him as one of the youngest university graduates in the world.
Researchers there were struck not simply by his age, but by the fact that he had already completed a bachelor's degree in physics and wanted to participate seriously in scientific research.
Laurent's own explanation was much simpler.
He loved learning.
During his time with the attoworld research team, he was exposed to laboratory techniques involving molecular analysis, blood samples and laser technologies with possible medical applications.
That experience also reflected something that would increasingly shape his long-term goals: Laurent did not want to remain confined to one scientific discipline.
Physics fascinated him, but so did biology, medicine, chemistry and technology.
Eventually, those interests would begin to converge.
Beyond the Headlines About IQ
Media coverage of gifted children often focuses heavily on IQ scores, and Laurent has frequently been described as having an IQ of at least 145.
The Max Planck Institute itself reported that scientists had assessed his IQ at 145 or higher.
That number has inevitably become part of the public story surrounding him.
But Laurent's academic record is more tangible than any single intelligence score.
An IQ test measures certain cognitive abilities under specific testing conditions. It does not automatically produce scientific discoveries, nor does it guarantee creativity, perseverance or success in research.
Scientific work requires much more.
Researchers have to absorb existing knowledge, identify worthwhile questions, understand mathematical and experimental methods, work with supervisors and colleagues, cope with failed ideas, and communicate their findings in ways that other scientists can evaluate.
Laurent's progression therefore cannot be reduced to a number.
By his early teens, he was not simply completing accelerated school examinations. He was participating in university-level physics and eventually doctoral research.
That distinction matters.
Entering the Strange World of Quantum Physics
Quantum physics is famously counterintuitive.
At the scale of atoms and subatomic particles, matter can behave in ways that have little resemblance to the everyday world.
Particles can display wave-like behavior. Quantum systems can exist in unusual combinations of states. Under extreme conditions, groups of particles can collectively exhibit properties that seem almost impossible when judged by ordinary experience.
One of the phenomena central to Laurent's broader research environment is the Bose-Einstein condensate, commonly abbreviated as BEC.
A Bose-Einstein condensate forms when certain particles known as bosons are cooled to extraordinarily low temperatures, close to absolute zero.
Under those conditions, many particles can occupy the same quantum state, producing collective quantum behavior on a scale much larger than that of an individual atom.
The University of Antwerp describes these ultracold atomic gases as exceptionally useful systems because researchers can control variables such as temperature, particle number, interaction strength and geometry.
That controllability allows physicists to use them as quantum simulators — systems through which complicated many-body phenomena can be investigated under carefully controlled conditions.
Laurent had already been studying this world before beginning his PhD.
The University of Antwerp lists his 2021–2022 master's thesis as Analog Physics with Excitations in Bose-Einstein Condensates, supervised by Jacques Tempere and Michiel Wouters.
His later doctoral research moved deeper into this field.
What Laurent's PhD Actually Studied
Laurent's doctoral thesis was titled:
Bose Polarons in Superfluids and Supersolids.
Although the terminology sounds intimidating, the central idea can be approached with an analogy.
Imagine placing an impurity — essentially a different particle — inside a surrounding quantum medium.
The impurity interacts with that environment.
As it moves, it affects the particles around it, and those interactions in turn change the way the impurity behaves.
The combined object is known as a polaron.
The University of Antwerp offers an intuitive description of the concept. An impurity traveling through a Bose-Einstein condensate can disturb the surrounding gas and create a deformation that effectively travels with it.
The university compares this loosely to someone walking across a trampoline: the person is not moving independently of the surface because the material beneath them deforms as they move.
In a Bose gas, the impurity together with the effects it creates in its surrounding quantum environment can be described as a Bose polaron.
Laurent investigated such systems in superfluids and supersolids.
A superfluid is a quantum state of matter capable of flowing with extraordinary properties, including behavior associated with effectively zero viscosity under appropriate conditions.
A supersolid is even stranger.
It combines crystalline order — the structured arrangement normally associated with solids — with superfluid behavior.
Those two characteristics appear, at first glance, difficult to reconcile.
Yet quantum mechanics allows matter to enter regimes where familiar categories such as "solid" and "fluid" become less rigid than they appear in ordinary life.
The University of Antwerp's official announcement for Laurent's doctoral defence explains that supersolidity combines superfluidity and crystalline order and that Bose-Einstein systems provide powerful platforms for studying many-body quantum phenomena.
This was the scientific territory Laurent was exploring at 15.
A Correction to a Popular Version of His Story
Some online accounts have described Laurent's PhD as research specifically exploring similarities between Bose-Einstein condensates and black holes.
That description mixes together different stages of his academic work.
The University of Antwerp's official records show that his PhD concerned Bose polarons in superfluids and supersolids.
His earlier master's research involved analog physics using excitations in Bose-Einstein condensates.
Analogue-gravity research can use condensed-matter or quantum systems to investigate mathematical behavior analogous to phenomena associated with gravitational systems, including aspects of black-hole physics.
But describing his 2025 doctoral dissertation simply as a study of the similarities between Bose-Einstein condensates and black holes would therefore be misleading.
