Matthew Stephens (born in 1970) is a smart scientist who works with statistics and genetics. He is a professor at the University of Chicago. He is famous for creating a special way to understand genetic information called the Li and Stephens model.

Education and Early Research
Matthew Stephens studied at Magdalen College at Oxford University. He earned his PhD there, which is a very high university degree. His main teacher and guide for his PhD was a scientist named Brian D. Ripley.
After finishing his PhD, he continued his research with another scientist, Peter Donnelly. This kind of research after a PhD is called postdoctoral research.
Career and Discoveries
While working with Peter Donnelly at Oxford University, Matthew Stephens helped create an important computer program. This program is called Structure. He worked on it with Jonathan Pritchard.
Understanding Population Structure
The Structure program helps scientists figure out how different groups of people are related. It looks at their DNA to see how populations have mixed over time. Imagine trying to trace your family tree back many generations; this program helps do that for whole groups of people. It helps understand population structure (how groups are organized) and genetic admixture (how genes from different groups have mixed).
The Li and Stephens Model
Later, Matthew Stephens helped develop another very important idea called the Li and Stephens model. This model is a clever way to understand how genes are passed down and how they change over time. It helps scientists study linkage disequilibrium, which is when certain genes or traits tend to be inherited together more often than expected. This model is very useful for studying human diseases and how populations have moved around the world.
Awards and Recognition
Matthew Stephens has received special awards for his important work.
- In 2006, he was given the Guy Medal (bronze) for his contributions to statistics.
- In 2023, he was chosen to be a Fellow of the Royal Society. This is a very high honor for scientists in the United Kingdom. It means he is recognized as one of the best scientists in the country.
