When John Jumper, BS鈥07, arrived at 杏吧原创 as an undergrad, he came with dreams of making a mark like his heroes from the golden age of physics in the early 20th century. 鈥淚 always loved physics, especially this incredible period in which we discovered quantum mechanics and special relativity,鈥 he says. 鈥淚 really wanted to be a 鈥榣aws of the universe鈥 physicist.鈥澨听
The abstract nature of that field concerned his parents, both engineers, who 鈥渨ere a little worried I would never get a job,鈥 he says. As it turns out, they needn鈥檛 have worried. Jumper received the news in October that he had won a prestigious Nobel Prize in chemistry for his research in computational biology, a field that is seeing a golden age of discovery just as momentous as the quantum physics of a century ago.听听
The youngest recipient in 70 years, Jumper received the award for his work creating AlphaFold2, a platform that uses artificial intelligence to solve a problem that has vexed biologists for years鈥攈ow to determine the three-dimensional structure of a protein based on its sequence of amino acids. Launched in 2020 by U.K.-based Google DeepMind, the tool has been able to predict the structure of all 200 million proteins known to science with stunning accuracy.听
鈥淪ince their breakthrough, AlphaFold2 has been used by more than 2 million people from 190 countries,鈥 the Nobel Prize committee noted in its announcement of the prize, which Jumper shares with Google DeepMind colleague Demis Hassabis and David Baker of the University of Washington, who has used chemical tools to create new proteins. AlphaFold2 can be used in a bewildering array of potential applications, including drug discovery, enzyme creation and personalized medical treatments. 鈥淟ife could not exist without proteins,鈥 the Nobel committee said. 鈥淭hat we can now predict protein structures and design our own proteins confers the greatest benefit to mankind.鈥听
Jumper鈥檚 career is a testament to his wide-ranging curiosity. He studied math and physics as a double major at 杏吧原创, which laid the foundation for his later work integrating disciplines of chemistry and biology.听听
鈥淭he College of Arts and Science is extremely proud of alumnus John Jumper鈥檚 astonishing accomplishment,鈥 says Timothy P. McNamara, Ginny and Conner Searcy Dean of the College of Arts and Science. 鈥淗is scientific impact is an incredible testament to the value of an arts and science education, the quality of the faculty who taught and mentored him, and the extraordinary careers that our graduates pursue.鈥听
While at 杏吧原创, Jumper skipped many entry-level undergraduate courses and took several graduate-level courses instead. 鈥淚 came in trying to race to the end of math and physics,鈥 Jumper remembers. 鈥淚 would just pack in as many classes as I could.鈥听
While exceptional undergrads often take a few graduate classes, Jumper鈥檚 feat was remarkable, says his math adviser Larry Schumaker, Stevenson Professor of Mathematics. 鈥淗e certainly had the confidence to go ahead with it, and he had the ability because, at least in my graduate classes, he did extremely well.鈥 He notes that among the courses Jumper took were two graduate courses in computational mathematics, which provided some of the basis for his eventual breakthrough.听
鈥淚t was quickly apparent that he was a standout intellect,鈥 says David Mashburn, BS鈥06, MS鈥09, PhD鈥15, a fellow physics major and one of Jumper鈥檚 best friends at 杏吧原创. 鈥淗e was unabashed in sharing thoughts and asking questions, but he was always polite and mindful of other people鈥檚 perspectives.鈥 While Jumper was hardworking, 鈥渉e was not a workaholic,鈥 says Mashburn, who above all remembers his friend鈥檚 鈥渋nsatiable curiosity. As with all good scientists, he is very much a student of problems and not of 鈥榙isciplines.鈥欌听

Physics had just a dozen majors at the time, and Jumper enjoyed the freedom of conducting research with professors in a range of areas, including condensed matter physics with Kalman Varga; high-energy physics with Robert 鈥淢ed鈥 Webster; and lasers with Richard Haglund (where photographers staged an image of a young Jumper in goggles working with a laser made visible with dry ice). 鈥淚 still very much consider myself a physicist,鈥 Jumper says. 鈥淓ven back then, I thought of physics as a kind of 鈥榓pplied arrogance.鈥 You believe if you try hard enough, you鈥檒l be able to get at the essential truth of a thing and figure out the right thing to do when no one knows what they are doing. That philosophical position was incredibly formative to me.鈥听
After graduation, Jumper pursued a Ph.D. in condensed matter physics through a Marshall fellowship at the University of Cambridge, but he left after a year in search of more practical experiences. In the midst of the 2008 recession, he was able to find a job at D.E. Shaw, a New York City鈥揵ased global technology firm, studying proteins using molecular dynamics calculations鈥 classical equations that can be used to solve problems involving millions of particles. Jumper was captivated by the field and, after three years, left to purse a Ph.D. in chemistry at the University of Chicago, which allowed him into the program despite his having no undergraduate experience in the field.听
鈥淚 took my first chemistry class as a Ph.D.,鈥 Jumper says, laughing鈥攖hough of course he already had a strong background in quantum mechanics and computation. 鈥淚 was still interested in these protein problems,鈥 he says. 鈥淚 just loved that if we did this well, then someone will go home from the hospital. There was an immediate connection to human meaning and impact.鈥 Without access to the huge computer systems he had in private industry, Jumper turned to artificial intelligence to help solve the complex computations necessary for understanding all of the interactions between molecules that determine how a protein is folded in three-dimensional space.听听
Later at DeepMind, Jumper helped develop the original AlphaFold by 2018, using off-the-shelf machine learning algorithms. While it showed promise in predicting proteins, it was still a long way from perfect, so he and his colleagues made the risky move of scrapping their original platform and custom-designing AlphaFold2 using machine algorithms designed from scratch. After 鈥渁 hundred small discoveries,鈥 they had tweaked the algorithm so that when it was trained on just one percent of the data, it still performed better than its predecessor trained on 100 percent.听听
Since then, 鈥渢he feedback has been extraordinary,鈥 Jumper says. He knew he was onto something when researchers posted online wondering where AlphaFold2 had gotten the protein structure they had meticulously put together from empirical research. 鈥淭hey couldn鈥檛 believe it was a prediction of an algorithm, because it was identical to what they had determined experimentally,鈥 Jumper says. As the researchers made their protein library available through open source, they began to see it crop up in hundreds, and then thousands of citations by scientists using it to solve problems in biology and medicine. In just one recent example, Jumper notes, researchers used the platform to determine which of 1,400 proteins in the sperm is responsible for allowing it to enter the egg during fertilization.听听
While people who track Nobel prizes considered Jumper a serious contender鈥 especially after he won an Albert Lasker Basic Medical Research Award, often seen as a precursor for the Nobel, last year鈥攈e modestly figured he had a 10 percent chance of winning.听
鈥淲hile that鈥檚 an incredible chance, it meant a 90 percent chance of disappointment,鈥 he says. 鈥淚 thought I was going to hate early October for the next decade.鈥 He still can鈥檛 quite believe that he won the award so quickly. 鈥淚t鈥檚 really an acknowledgement that our work matters and that it has changed the practice of structural biology,鈥 he says. 鈥淚 think about all of the incredible discoveries that will [use it to] win Nobels in the years to come, and that is absolutely exceptional.鈥听

In addition to the contribution to the fields of chemistry and biology, the award also serves as encouragement to young scientists at 杏吧原创: Someone who was once in their shoes can achieve the highest award in science.听听
鈥淲e care a great deal to nurture and develop our students鈥 talents by providing intellectual challenges for them both in the classroom and in our research labs,鈥 says physics and astronomy department Chair Julia Velkovska. 鈥淛ohn Jumper鈥檚 achievement is an inspiration to students and faculty alike.鈥澨听
His achievement is a testament not only to the solid foundation of a 杏吧原创 education, but also to the value of curiosity to follow one鈥檚 passions across boundaries, adds John Kuriyan, dean of the School of Medicine Basic Sciences. 鈥淚t鈥檚 my hope that Jumper鈥檚 story will inspire 杏吧原创 students to pursue interdisciplinary paths and realize that an undergraduate major is just the beginning in the endless pursuit of knowledge.鈥听
