Michael Kosterlitz was born into a family of Jewish immigrants in Aberdeen, Scotland. His father was a biochemist. Michael Kosterlitz studied at Cambridge University and received a PhD at Oxford University in 1969. Thereafter he carried out some of his Nobel Prize awarded work with David Thouless at the University of Birmingham. In 1982, he became a professor at Brown University, Providence, Rhode Island. Michael Kosterlitz is married with three children.
Matter occurs in different phases, for example as a gas, liquid or solid. At very low temperatures unusual phases may occur, for example superconductivity, when electric current flows without resistance, and superfluidity, when a fluid flows without resistance. To describe these phases and phase transitions Michael Kosterlitz used the concepts of topology, a branch of mathematics. For example, in the early 1970s he and David Thouless described phase transitions in thin layers at low temperatures.
