Abstract:
Variable projection methods are among the classical and efficient methods to solve separable nonlinear least squares problems. In this talk, I will present the original variable projection method, its use to solve large-scale  blind deconvolution problems, and some new variants that preserve the edges in the solution.

Speaker Bio:
Dr. Malena I. Español is an assistant professor in computational mathematics at the School of Mathematical and Statistical Sciences at Arizona State University. She earned her B.S. in mathematics from the University of Buenos Aires, Argentina, and M.S. and Ph.D. in mathematics from Tufts University. After graduation, Dr. Español was a postdoctoral scholar at the California Institute of Technology. In 2012, she started a faculty position at The University of Akron where she stayed until 2019, when she joined ASU. Her research interests are in the development, analysis, and application of mathematical models and numerical methods for solving problems arising in science and engineering, with a focus on problems related to materials science, image processing, and medical applications. She leads the Inverse Problems and Imaging research group at ASU and her research has been supported by NSF and DOE.  She has been an active member of the Association for Women In Mathematics (AWM) and the Society for Industrial and Applied Mathematics (SIAM), by serving in multiple committees. She is a Math Alliance and AWM mentor, a 2013-2014 MAA Project NExT Fellow, and the 2022 Karen EDGE Fellow.

Intended Audience:
Undergraduates, graduates, and experts. Those with interest in the topic.
