Malgo Peszynska received her Ph.D. in Mathematics from University of Augsburg, and M.S. 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; 2017 Kosciuszko Foundation College of Eminent Scientists, OSU Mathematics Graduate mentoring award (2016), Joel Davis Excellence award (2016), 2009-10 Fulbright Research Fellow, as well as Mortar Board professor (2004). Malgo also is the 2022-24 Joel Davis Faculty Scholar. She believes in "paying it forward" : 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) and AWM (Association for Women in Mathematics), is serving on editorial boards for 4 journals, and on the Executive Board of Pacific Math Alliance. 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.


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 2019-2023 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.
