Early Life and Education
The public record contains no detailed account of Fauci’s early life or undergraduate education. What is known is that she entered the mathematical sciences in the 1980s, a period when computational methods were rapidly expanding in both engineering and biology. Her doctoral work laid the foundation for a career that would bridge rigorous mathematics and complex living systems.
Academic Career
Tulane University
Lisa Fauci is currently the Pendergraft Nola Lee Haynes Professor of Mathematics at Tulane University. In this role, she teaches advanced courses in numerical analysis and computational fluid dynamics, mentors graduate students, and directs research projects that explore the mathematical underpinnings of biological systems.
Leadership in Professional Societies
Fauci’s influence extends beyond her university. She served as president of the Society for Industrial and Applied Mathematics (SIAM) from 2019 to 2020, a period during which she helped steer the society toward greater interdisciplinary collaboration and outreach. Her election to the National Academy of Sciences in 2023 further underscores her standing among the country’s leading scientists.
Research Focus
Lisa Fauci’s research portfolio is organized around three interrelated domains: computational fluid dynamics (CFD) applied to biology, numerical analysis, and mathematical biology. Each area informs the others, creating a cohesive research agenda that advances both theory and application.
Computational Fluid Dynamics in Biology
CFD traditionally deals with the numerical simulation of fluid flow governed by the Navier–Stokes equations and related models. Fauci adapted these tools to biological contexts where fluid–structure interactions are crucial. By resolving the motion of fluids around microscopic organisms or within cellular environments, her work illuminates how physical forces shape biological function.
Sperm Motility
One of Fauci’s most cited research areas concerns sperm motility. Sperm cells swim through viscous fluids using flagellar waves. Modeling this motion requires coupling the fluid dynamics of the surrounding medium with the elastic properties of the flagellum. Fauci’s computational models provide insight into how sperm generate propulsion, how they respond to chemical gradients, and how physical constraints affect fertility.
Phytoplankton Dynamics
Phytoplankton—microscopic photosynthetic organisms—play a critical role in global carbon cycling. Their movement, aggregation, and distribution are influenced by fluid flows in the ocean. Fauci’s CFD simulations help predict how phytoplankton respond to turbulence, how they form blooms, and how these processes impact marine ecosystems and climate models.
Numerical Analysis and Scientific Computing
Numerical analysis is the mathematical study of algorithms that approximate solutions to continuous problems. Fauci’s work in this area focuses on developing stable, accurate, and efficient algorithms for solving partial differential equations that arise in CFD and biological modeling. Her contributions include error estimation techniques, adaptive mesh refinement strategies, and parallel computing frameworks that enable large-scale simulations.
Mathematical Biology
Mathematical biology applies mathematical reasoning to biological questions. Fauci’s interdisciplinary approach combines rigorous analysis with biological relevance, ensuring that models capture essential mechanisms while remaining tractable. Her research spans from single-cell dynamics to population-level phenomena, demonstrating how mathematics can illuminate the behavior of living systems.

- Educational Influence: Through her teaching and mentorship at Tulane, Fauci has trained a generation of mathematicians who continue to push the boundaries of computational and biological research.
Future Directions
While Fauci’s current work focuses on sperm motility and phytoplankton dynamics, her broader research interests suggest several promising directions:
- Multiscale Modeling: Integrating molecular, cellular, and ecosystem-level models to capture complex biological behavior across scales.
- Machine Learning Integration: Employing data-driven techniques to complement physics-based simulations, especially in parameter estimation and uncertainty quantification.
- Climate Impact Studies: Extending phytoplankton models to assess how ocean warming and acidification affect marine carbon sequestration.
These trajectories align with the growing need for quantitative, predictive tools in biology and environmental science.
