Early life

Tuckerman was born in New York City in 1956. Her mother was a journalist for the Agence France Presse covering the United Nations who had left France during World War II, and her father was a New York City union negotiator and devoted amateur pianist. She attended Hunter College High School.

Education

Tuckerman attended Wesleyan University and Princeton University and obtained a PhD in applied mathematics from Massachusetts Institute of Technology in 1984.

Career

Tuckerman first worked at the Saclay Nuclear Research Centre in France and then at University of Texas at Austin, where she was a postdoc at the Center for Nonlinear Dynamics and then a faculty member in the department of mathematics. In 1994, she became a researcher at the Centre National de la Recherche Scientifique in France. She has also taught at Ecole Polytechnique and at École normale supérieure (Paris).

Research

Laurette Tuckerman studies hydrodynamic instabilities using the methods of computational fluid dynamics and of bifurcation theory. She has studied large number of these configurations: Couette, Poiseuille and von Karman flows, Rayleigh-Benard and Marangoni convection in simple and binary fluids, and in cylindrical, spherical and planar geometries. In some of these flows, she made the first observations of more exotic scenarios, including sniper (saddle-node infinite-period) bifurcations, robust heteroclinic cycles, and codimension-two points. In order to accomplish this, she developed a suite of methods for modifying a time-dependent nonlinear code to carry out Newton's method for computing steady states and traveling waves and Arnoldi's method for finding eigenvectors. These matrix-free methods have been used to study problems not only in fluid dynamics, but also in Bose-Einstein condensates and electrochemistry. She carried out the first linear stability analysis for viscous fluids of Faraday waves, the standing waves which appear on a vertically vibrated fluid layer, and their first full numerical simulation. She has also studied the laminar-turbulent patterns which occur during transition to turbulence in wall-bounded shear flows.

Awards

In 2002, she was elected as fellow of the American Physical Society and in 2018 she became a fellow of Euromech. She gave the Ludwig Prandtl Memorial lecture at the 2024 GAMM meeting. She received the Émilie Du Châtelet prize from the Société Française de Physique in 2025.
