Sarah Louise Waters is a British applied mathematician whose research interests include biological fluid mechanics, tissue engineering, and their applications in medicine. She is a professor of applied mathematics in the Mathematical Institute at the University of Oxford, a Fellow of St Anne's College, Oxford,^[1] and a Leverhulme Trust Senior Research Fellow of the Royal Society.^[2]

Waters completed her Ph.D. at the University of Leeds in 1996. Her dissertation, Coronary artery haemodynamics: pulsatile flow in a tube of time-dependent curvature, was supervised by Tim Pedley.^[3] She was named a professor at Oxford in 2014.^[4]

In 2012 she won a Whitehead Prize "for her contributions to the fields of physiological fluid mechanics and the biomechanics of artificially engineered tissues".^[5]

In 2019, Waters was elected a fellow of the American Physical Society.^[6]
