Dr. Marcus received his PhD from Washington University, studying the neurophysiology of the primate cerebral cortex in the laboratory of Dr. David Van Essen. He then went on to do post-graduate work in neuroinformatics in the Department of Psychology at Washington University prior to forming his own laboratory in the Mallinckrodt Institute of Radiology at Washington University School of Medicine. His laboratory, the Neuroinformatics Research Group (NRG), includes an interdisciplinary team of engineers, scientists, software developers, and informaticists all contributing towards the common goal of enabling imaging in biomedical research. The laboratory develops XNAT, the world’s most widely used imaging informatics platform, and contributes to the international biomedical informatics infrastructure through a portfolio of NIH-funded projects. Dr. Marcus directs imaging informatics operations for a number of large scale research programs, including the Human Connectome Project, the Dominantly Inherited Alzheimer Network, and the Neuroimaging Informatics and Analysis Center. Dr. Marcus is also founder and president or Radiologics, Inc., which has developed a XNAT CR, a 21 CFR Part 11 compliant version of XNAT, and provides custom imaging informatics and cloud-hosted applications to academic and industry organizations.
