Joyce McLaughlin

Ford Foundation Professor of Mathematics, IPRPI Director

Inverse Problems in Acoustics and Mechanics, Biomechanical Imaging, Inverse Spectral Theory and Inverse Nodal Problems

McLaughlin is the Ford Foundation Professor in the Department of Mathematical Sciences and the director of IPRPI, the Inverse Problems Center at Rensselaer Polytechnic Institute. She frequently lectures on her work, where applications include medical imaging, ocean acoustics, and inverse problems in vibrating systems.

McLaughlin was first known for her work in inverse spectral theory, in which national frequencies and/or subsets of mode shapes, such as nodal sets, of a vibrating system are used to identify physical properties.  She presented this work in 8 Conference Board of Mathematical Sciences Lectures in 2001.  Furthermore, her work in this area was presented at the International Congress of Mathematicians in Zurich in 1994,

More recently she has become known for her work in biomechanical imaging of tissue.  The physical process that produces the data is the dynamic movement of tissue at a low amplitude of displacement (on the order of microns) and the model for that process is used to create images of biomechanical tissue properties.  These images are being utilized, together with ultrasound or MRI images, as a new medical diagnostic tool.  The biomechanical imaging work was the subject of McLaughlin’s AWM/SIAM 2004 Kovalevsky Lecture and prize.

McLaughlin also works in shallow water acoustics finding biomasses in ocean waveguides and in geophysics where the goal is to identify fault geometry from frequent low level earthquakes in the fault region.

She is an inaugural Fellow of the Society for Industrial and Applied Mathematics Society (SIAM), an inaugural Fellow of the American Mathematical Society, a member of the Scientific Board of (AIM) American Institute for Mathematics, and a member of the International Advisory Board for the journal Inverse Problems.
