Biography

Katherine Muller is an Earth scientist at Pacific Northwest National Laboratory (PNNL). She received her doctoral in environmental engineering from Tufts University in Medford, MA and completed her post-doctoral training at Oak Ridge National Laboratory. Her research focuses on linking experimental testing to contaminant fate and transport modeling to understand, predict, and inform subsurface models and remediation.
