Mohammad Abbas Yaseen is an Assistant Professor in the Department of Bioengineering at Northeastern University's College of Engineering, where he has been on the faculty since January 2020. He earned his B.S. in Biomedical and Electrical Engineering from Johns Hopkins University in 2002 and his Ph.D. in Bioengineering from Rice University in 2008. At Northeastern, Yaseen directs the Optical Microscopy & Neuro-Imaging (OMNI) Lab, which develops and applies high-resolution optical technologies to investigate brain function in rodent models of human disease. The lab focuses on advanced optical microscopy methods to study metabolic and immune features during healthy brain function and their disease-related alterations, with the goal of characterizing the etiologies of debilitating brain pathologies such as stroke and neurodegenerative diseases. His current NIH-funded work examines neuroimmune and neurovascular alterations during Alzheimer's disease progression. His research sits at the intersection of optical microscopy, brain function, and energy metabolism, and his publications—appearing in venues such as the Journal of Cerebral Blood Flow and Metabolism, eLife, and PLoS One—have explored topics including two-photon imaging of capillary red blood cell flux in the mouse brain and phasor analysis of NADH fluorescence to detect mitochondrial metabolic disruptions in the cerebral cortex. Prior to joining Northeastern, he was affiliated with the Optics Division at the Massachusetts General Hospital Martinos Center for Biomedical Imaging.
