Malgorzata Peszynska

Department of Mathematics



Malgo Peszynska received her PhD in Mathematics from University of Augsburg, and MS and Habilitation from Warsaw University of Technology. She held academic positions at Polish Academy Of Sciences, Warsaw University of Technology, Purdue University, and The University of Texas at Austin. She has been at Oregon State since 2003, as a full professor since 2012, and as Graduate Chair 2015-2019. In 2019-21 she served as a Program Director at the NSF DMS (National Science Foundation, Division of Mathematical Sciences). She is a 2020 AAAS Honorary Fellow; 2021 SIAM Geosciences Career Prize recipient; OSU Mathematics Graduate mentoring award and Joel Davis Excellence award, as well as Mortar Board professor (2004). She believes in "paying it forward" and is engaged in external and university service via editorial work and conference organization: M. Peszynska also held leadership and service positions at SIAM (Society for Industrial and Applied Mathematics) including President of SIAM Pacific Northwest Section (2018-20) and SIAM Geosciences (2009-10). She directed several postdocs, doctoral, masters and undergraduate students; see MP people. Her research is in broadly defined applied and computational mathematics modeling of real life phenomena, with foundations in analysis and other core mathematics, and with interdisciplinary applications and collaborations in geosciences (hydrology and oceanography), engineering, and material science.


Ph.D. in Mathematics, University of Augsburg, 1992

Habilitation in Mathematics, Warsaw University of Technology, 2011

M.Sc. in Applied Mathematics, Warsaw University of Technology, 1986


Malgo Peszynska's research interests are in applied mathematics and computational modeling of real life phenomena. Originally trained in pure mathematics, she came to applied mathematics projects through her interest in parallel and high performance computing. Since her PhD she has worked on models of flow and transport using mathematical and numerical analysis as well as computer simulations to understand these phenomena better across the various time and spatial scales. She is involved in a variety of interdisciplinary projects with academic, national lab, and industry collaborators from hydrology, oceanography, statistics, environmental, petroleum, civil and coastal engineering, physics, and materials science. Her research projects were funded by NSF, DOE-NETL and by DOE; her recent projects include the 2015-2021 NSF-DMS 1522734 "Phase transitions in porous media across multiple scales", and 2019-2024 NSF-DMS 1912938 on "Modeling with Constraints and Phase Transitions in Porous Media". Her recent work involves modeling flow, mass and energy transport, and coupled geomechanics processes in the Arctic as well as under seafloor and terrestrial reservoirs. She also worked on mathematical modeling of microbial competition and biofilm formation in porous media, as well as on semiconductor models across the scales.
