Education and Career

John Bush received his BSc and MSc in physics from the University of Toronto. He acquired his Ph.D. in geophysics at Harvard University in 1993. Bush pursued a postdoctoral program from 1993 to 1997 at the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. He joined the Massachusetts Institute of Technology faculty in 1998, was tenured in 2004, and was promoted to a professor’s position in 2009.

Research Interests

Initially, Bush worked on environmental and geophysical flow and later shifted to surface tension-driven phenomena and their applications in biology. Here are the key directions of John’s research:

Geophysical flows

Early research work has been dedicated to the dynamics of extensive flows dominated by the Earth’s rotation and the influence of stratification. His other geophysical research interests have included the Earth’s lithosphere dynamics, tektites, and sedimentation dynamics. 

Pilot-wave hydrodynamics

Yves Couder and Emmanuel Fort discovered that droplets walking on a vibrating fluid bath exhibit features previously thought to be unique to the quantum realm. Since 2010, their research has focused on identifying new hydrodynamic quantum analogs in the laboratory and theoretically rationalizing the emergent quantum-like behavior. John Bush has developed and explored a broader class of pilot-wave systems that provide a mathematical bridge between the walking-droplet system and the dynamics proposed by Louis de Broglie and others. Bush suggests reading the reviews on the subject, especially the most recent one, Hydrodynamic Quantum Analogs, as published in 2020 in Reviews of Progress in Physics.

Interfacial flows

Much of Bush’s work at MIT has been directed toward fluid systems dominated by the influence of surface tension.

Fluid dynamics of the pandemic

John Bush and Lydia Bourouiba conducted an integrated experimental and theoretical study of the dynamics of coughing and sneezing, which revealed that small respiratory drops are transported farther than larger drops due to the gas flows associated with exhalation. Bush has also studied the fate of the smallest pathogen-bearing droplets, which may be mixed uniformly throughout an indoor space by ambient air flows.

Biocapillarity and biofluids

Biocapillarity is the study of biological systems dominated by interfacial effects, with Bush’s studies focusing on natural strategies for water-repellency, walking on water, underwater breathing, and drinking.
