Three new faculty members have joined Mallinckrodt Institute of Radiology (MIR) at Washington University School of Medicine in St. Louis.

Matthew Glasser, MD, PhD, joins the neuroradiology section as an instructor. Glasser recently completed his diagnostic radiology residency at Mallinckrodt Institute of Radiology (MIR) as a part of the American Board of Radiology’s Holman Research Pathway. He will be completing a neuroradiology fellowship while pursuing his research on developing and applying new brain imaging analysis methods to tackle important questions in systems neuroscience.

Glasser is best known for mapping the human brain’s neocortical areas non-invasively with a multi-modal approach as a part of the Human Connectome Project. He co-leads a brain imaging laboratory with David Van Essen, PhD, in the Department of Neuroscience and the Computational Imaging Research Center at MIR.  Glasser also co-leads with Daniel Marcus, PhD, the informatics, data analysis and statistics core of the Adult Aging Brain Human Connectome project, a longitudinal continuation of the Human Connectome Aging project funded by the National Institute on Aging. He has been recognized as a “Highly Cited Researcher” by the Institute for Scientific Information annually since 2018.

Glasser earned both his medical degree and doctorate in neuroscience from Washington University in St. Louis. He obtained his bachelor of science in neuroscience from Emory University in Atlanta and completed post-baccalaureate pre-medical studies at Johns Hopkins University in Baltimore.


Scott Marek, PhD, joins the Neuroimaging Labs Research Center as an assistant professor. Marek comes to us from the Department of Psychiatry, where he has been an instructor since 2020. As a pediatric neuroimaging investigator, his research primarily involves applying innovative neuroimaging on single individuals and big data approaches to understanding and eventually treating the neurodevelopmental processes that contribute to the emergence of psychiatric illness during adolescence.

Marek earned his doctorate in neuroscience from the University of Pittsburgh and his bachelor of science in psychology from John Carroll University in University Heights, Ohio.


Arash Nazeri, MD, joins the neuroradiology section as an assistant professor. Nazeri recently completed a neuroradiology fellowship with MIR after having completed a diagnostic radiology residency, also at MIR. His research focus is on imaging and perturbing brain microstructure and neurofluids in health and disease using diffusion-weighted MRI and focused ultrasound. His other interests include developing and optimizing MRI protocols for advanced neuroimaging studies.

Nazeri will be pursuing this research as a member of the Biomedical MR Center. He has been the recipient of numerous awards such as the Canadian Institute of Health Research (CIHR) Fellowship award in 2015, the Radiological Society of North America (RSNA) Research and Education Foundation Research Resident Grant for 2019, and RSNA Roentgen Resident/Fellow Research award in 2021. Recently, he received the Foundation of the American Society of Neuroradiology (ASNR) grant to support his research on early postnatal maturation of white matter microstructure.

Nazeri earned his medical degree at Tehran University of Medical Sciences in Iran and completed a three-year postdoctoral research fellowship at the University of Toronto. He then did a one-year internship in internal medicine at the Nassau University Medical Center, East Meadow in New York.
