Biography:
Dianne Prost O'Leary is a Distinguished University Professor Emerita of computer science, and also holds joint appointments in UMIACS and in the Applied Mathematics and Statistics and Scientific Computing Program.
O'Leary's research focuses on computational linear algebra and optimization, with applications including solution of ill-posed problems, image deblurring, information retrieval, protein configuration, and quantum computing.
She has authored two books, more than 100 research publications on numerical analysis and computational science, and 30 publications on education and mentoring. Perhaps her most widely-read publication is an online guide called, "Graduate Study in the Computer and Mathematical Sciences: A Survival Manual." Twenty-one students have received doctorates under her direction.
O'Leary is a member of AWM and a Fellow of SIAM and ACM. She was awarded a Doctor of Mathematics degree, honoris causa, from the University of Waterloo in 2005; received the Board of Visitors Distinguished Faculty Award, College of Computer, Mathematical, and Physical Sciences, University of Maryland, in 2007; and was chosen to be the 2008 AWM-SIAM Sonia Kovalevsky Lecturer.
She has chaired the program committees of major conferences and has organized two mentoring workshops. O'Leary is editor-in-chief of the SIAM Journal on Matrix Analysis and Applications, and co-edits the column, "Your Homework Assignment" for Computing in Science and Engineering.
She earned a B.S. in mathematics with a physics minor from Purdue University and a doctorate in computer science from Stanford University.
