Dr Karl Deisseroth had barely begun processing the news that he had won the 2026 Nobel Prize in Physiology or Medicine when everyday family responsibilities called.
After spending hours answering congratulatory calls, speaking with journalists and discussing his groundbreaking work in neuroscience, the Stanford University professor took a break from the celebrations to make school lunches for his children.
The 54-year-old California scientist had received the early-morning call from the Nobel Assembly in Stockholm after working late into the night. Yet despite the significance of the announcement, his next morning still included a familiar task for any parent: getting his children ready for school.
From Nobel Call to School Lunches
Deisseroth was at his home in Stanford, California, when the Nobel news arrived.
A self-described night owl, he had been working late, reviewing papers and emailing students before finally lying down. Then his phone rang with the news that he had been selected for one of the world’s most prestigious scientific honours.
He said he was initially so stunned that he briefly struggled to speak.
“I almost felt as if I’d lost the power of forming words,” he told the Associated Press, although he quickly recovered enough to begin a series of interviews.
Sleep, however, was not really an option.
As journalists and Stanford communications staff continued contacting him, a photographer arrived at his home at around 3.30am.
Inside, Deisseroth was taking calls from the couch while his wife, Dr Michelle Monje-Deisseroth, helped make coffee for members of the Stanford team who had joined the celebration.
But by 6.30am, Deisseroth told university staff that he needed an hour away from the interviews.
His children would soon be awake.
And they needed their lunches.
A Nobel Laureate and a Parent
The contrast between the extraordinary news and the ordinary family routine quickly became one of the most memorable details surrounding Deisseroth’s Nobel win.
On one hand, he had just been recognised internationally for research that transformed modern neuroscience.
On the other, he still had to prepare food for his children before they headed to school.
The moment offered a glimpse into the family life behind the scientist’s public achievements.
Deisseroth’s wife is also a scientist. Michelle Monje-Deisseroth is a Stanford professor and pediatric neuro-oncologist, as well as an investigator with the Howard Hughes Medical Institute.
She was beside him as the Nobel announcement unfolded and was reportedly less surprised than her husband that his work had received the honour.
The couple live in Stanford faculty housing, where Nobel laureates are not exactly unusual neighbours.
As Monje-Deisseroth reportedly put it when someone wondered whether the late-night activity might bother the neighbours, there are “a lot of Nobels in the neighborhood.”
The Science Behind the Nobel Prize
Deisseroth shared the 2026 Nobel Prize in Physiology or Medicine with German scientists Peter Hegemann and Georg Nagel.
The three researchers were recognised for pioneering work on optogenetics, a technique that allows scientists to use light to control the activity of nerve cells.
The field combines genetics and light-sensitive proteins to give researchers an unusually precise way of switching neurons on and off.
Hegemann and Nagel’s discoveries involving light-sensitive proteins helped establish the foundations of the technology, while Deisseroth played a crucial role in adapting the approach for neuroscience and demonstrating how it could be used to control specific brain circuits.
Their work has transformed the way scientists study the brain.
Instead of simply observing neural activity, researchers can use optogenetic methods to manipulate particular groups of neurons and investigate how they influence behaviour and biological processes.
Research With Potential Medical Impact
For Deisseroth, the significance of the Nobel Prize goes beyond scientific recognition.
He is both a psychiatrist and a physician-scientist, and he said he is particularly interested in what the research could eventually mean for people living with neurological and psychiatric conditions.
He specifically mentioned patients with autism and depression, while also emphasising the importance of understanding how the brain functions at a fundamental level.
Optogenetics has become an important research tool for investigating conditions and processes involving the brain and nervous system.
Researchers are also exploring whether technologies inspired by the approach could eventually contribute to treatments for conditions ranging from neurological disorders to vision problems.
The technique remains primarily a research tool, but its ability to precisely manipulate neural circuits has opened new possibilities for understanding diseases that have historically been difficult to study.
A Groundbreaking Career Meets an Ordinary Morning
The Nobel announcement marked a major moment in Deisseroth’s scientific career.
The prize carries an award of 12 million Swedish kronor, shared among the three laureates, and recognises discoveries that have fundamentally changed neuroscience.
Yet the morning after his historic achievement was not spent entirely discussing neurons, laboratories or Nobel ceremonies.
It involved school schedules, children waking up and packed lunches.
For Deisseroth, that ordinary responsibility could not simply be postponed because he had become a Nobel laureate overnight.
After a night of interviews and congratulations, the scientist had a more immediate assignment waiting at home — making sure his children had something to take to school.
It was an unusually relatable moment following an extraordinary achievement: a Nobel Prize winner stepping away from the spotlight to do one of the everyday jobs of parenthood.
