Irina Pettersson is an academic affiliated with the University of Gothenburg, focusing on research in asymptotic analysis, homogenization, and partial differential operators. Her work addresses mathematical physics problems that describe physical phenomena such as electromagnetic wave scattering by small particles and heat transfer. Pettersson specializes in classical homogenization theory, which studies the properties of mixtures of materials across different scales—from the microscopic level that details microstructures to a macroscopic perspective that represents the overall size and behavior of the material. This theory offers rigorous methods to substitute heterogeneous materials with new, homogeneous materials, allowing for simplified calculations and analyses. Notable applications of her research include the derivation of the Darcy law for transport in porous media and the Navier-Stokes equations. Additionally, she is interested in signal propagation in neurons, particularly in deriving the 1D nonlinear cable equation and developing a 3D model based on the Hodgkin-Huxley model, which explores current flow through ionic channels in neural membranes.
