Barbara joined the mathematics department in 2002. Previously, she earned her masters degree at the University of Gdansk and a PhD at Adam Mickiewicz University in Poland. She held postdoctoral positions at Katholieke Universiteit Leuven in Belgium, then at Leiden University in The Netherlands, and then at the University of Strathclyde in the United Kingdom. She also held an assistant professorship at the University of Gdansk and a visiting professorship at Arizona State University before joining Boise State University.

Barbara’s area of expertise is in the numerical and theoretical analysis of ordinary differential equations, partial differential equations, delay differential equations, Volterra integro-differential equations and functional differential equations. Applications of her work include medicine, cancer research, biology, neuroscience, population dynamics, electromagnetics and fluid mechanics. She also works on mathematical modeling, stability, well-posedness, the development and implementation of numerical methods, and the development of numerical software.
