Maureen Joel Lagos

Adjunct Professor in Materials Science and Engineering

Dr. Lagos is an Adjunct Professor in the Materials Science and Engineering (MSE) Department, at McMaster University, and he has joined the CCEM as an Adjunct Research Associate in 2018. His current research focuses on the understanding of low-energy excitations (phonon, plasmons) in novel materials using electron probes. He has also worked on the temporal aspects of the inelastic electron scattering associated with plasmons excitations. In addition, he also has devoted efforts to understand the structural effects on the quantum conductance of metal nanowires using in-situ HRTEM.
