Maureen Lagos

Associate Professor in Materials Science and Eng

Dr. Lagos is an Associate Professor in the Materials Science and Engineering (MSE) Department at McMaster University. He currently oversees the design and construction of an ultra-quiet room for a new state-of-art microscope at the CCEM. By harnessing the power of electron spectroscopic and imaging techniques, he investigates low-energy excitations (phonon, plasmons) and transitions in novel materials with potential for infrared photonic, heat transport and quantum material applications. He also possesses expertise in temporal aspects of the inelastic electron scattering associated with collective excitations, quantum electronic transport, and mechanical properties of nanostructures.

Affiliation: Materials Science and Engineering (MSE)
