Biography

Dr. Alexandra Valsamakis is an associate professor of pathology at the Johns Hopkins University School of Medicine. She holds joint secondary appointments in molecular medicine and immunology, and serves as director of Clinical Virology and Molecular Microbiology.

She received an M.D. from University of Pennsylvania and a Ph.D. in microbiology from the Medical College of Pennsylvania. After a residency in pathology at the University of California-San Diego, she completed two fellowships at Johns Hopkins, one in medical microbiology and a second in microbiology and immunology.

Dr. Valsamakis’ research focuses on the detection, identification, and therapeutic monitoring of infectious diseases, particularly viral infections.

She serves on the editorial boards of Diagnostic Microbiology and Infectious Diseases and Manual of Clinical Microbiology, and is an ad hoc reviewer for Clinical and Diagnostic Laboratory Immunology, Journal of Clinical Microbiology, Journal of Molecular Diagnostics and Journal of Viral Hepatitis. She is a member of the American Society for Microbiology, the Association for Molecular Pathology, the Infectious Disease Society of America and the Pan-American Society for Clinical Virology. She is certified in clinical pathology by the American Board of Pathology.

    Research Summary

    Dr. Valsamakis’ research focuses on the detection, identification, and therapeutic monitoring of infectious diseases, particularly viral infections. Her current work entails:

    1. Improving molecular assays that are critical for the management of hepatitis C and hepatitis B infections
    2. Devising quantitative assays for viral infections and studying their clinical utility particularly in immunocompromised patients
    3. Investigation of the performance and utility of automated nucleic acid preparation instrumentation in the clinical laboratory. Her lab uses a variety of conventional (cell culture, antigen detection) and molecular techniques (nucleic acid amplification, primarily PCR and real time PCR).
