Personal History:

Dr. Alan Schmaljohn is known principally as a virologist, with breadth of knowledge and expertise in vaccine discovery, immune responses, and antibody-based therapies for hazardous and emerging arboviruses and viral zoonoses. Currently a Professor of Microbiology and Immunology at the University of Maryland School of Medicine in Baltimore, Dr. Schmaljohn retired in 2007 from a 21-year civilian career with the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) in Frederick, MD. There, he served principally as leader of research and development teams, much of it in the capacity of Chief, Viral Pathogenesis and Immunology Branch. Before USAMRIID, Dr. Schmaljohn had been an Assistant Professor at the University of Maryland, this after postdoctoral positions at UMB and Johns Hopkins. In graduate school, he had transformed his undergraduate degree in Medical Technology (from the University of Nebraska) into a passion for infectious diseases, which flourished at Colorado State University (CSU) in a scientific milieu that included the veterinary school and the nearby arbovirology branch of the CDC. Dr. Schmaljohn received his PhD in Microbiology from CSU in 1981. His laboratory interests and published works have spanned several viral genera (filoviruses, orthopoxviruses, alphaviruses, hantaviruses, bunyaviruses, arenaviruses); immunologic niches (cytotoxic T lymphocytes, humoral immunity including monoclonal antibodies, peptides, anti-idiotypes, dendritic cells); virologic topics (isolation and characterization of new viruses, receptors, antibody escape mutants, epitope mapping, reassortants, envelope structure/function, pathogenesis); and vaccine strategies (alphavirus replicons, DNA vaccines, adenovirus, baculovirus recombinants, vaccinia virus recombinants, classical live or killed vaccines, virus-like particles). Seminal scientific contributions have included a candidate vaccine for Marburg virus, isolation of an American hantavirus now called Sin Nombre virus, and establishment of the importance of non-neutralizing antibodies in resistance to viral infections. Schmaljohn is an inventor on several patents, including new vaccines or treatments for poxviruses, Marburg, and Ebola viruses.
