Overview

Michael Levitt (Hebrew: מיכאל לויט) was born 9 May 1947 and is a South African-born biophysicist best known for founding computational approaches to structural biology. He is a Fellow of the Royal Society (FRS) and has held a long-term professorship in structural biology at Stanford University. Levitt's work helped make it possible to simulate large biomolecules and the chemistry that occurs within them.

Research and contributions

Levitt pioneered methods that combine different levels of physical description — from simplified, coarse-grained models to detailed quantum mechanical calculations — to study proteins, nucleic acids and enzyme reactions. These multiscale techniques allow researchers to treat the chemically active site of a molecule with high precision while representing the surrounding structure in a computationally efficient way.

Key ideas and methods

  • Multiscale modeling: integrating quantum and classical descriptions to capture chemical reactivity in large systems.
  • Coarse-graining: simplifying parts of a macromolecule to reduce computational cost while retaining essential behavior.
  • Computer simulation of protein structure and dynamics, enabling hypotheses about folding, stability and mechanism.

Career highlights

Levitt trained and worked across physics, chemistry and biology, bringing computational tools into structural problems that had previously been accessible only to experimental techniques. Since joining Stanford in 1987 he has supervised students and collaborated widely across disciplines, contributing software, algorithms and conceptual frameworks that influenced computational molecular science.

Nobel Prize and significance

In 2013 Levitt shared the Nobel Prize in Chemistry with Martin Karplus and Arieh Warshel for "the development of multiscale models for complex chemical systems." The award recognized how their work bridged theoretical chemistry and biological function, enabling detailed studies of enzyme mechanisms and other biomolecular processes that are crucial to life.

Applications and legacy

Methods that grew from Levitt's research are applied in enzyme mechanism studies, rational drug design, protein engineering and the interpretation of structural data. His influence is both practical — through tools that speed up simulation and modeling — and conceptual, by showing how different levels of theory can be combined to address complex biological problems.
