Alexandra Valsamakis, M.D., Ph.D.

Primary Appointment in Pathology; Joint Appointment in Molecular Medicine and Immunology (BSPH)
Member, Graduate Program in Molecular Microbiology and Immunology (BSPH)

My research is focused on the detection, identification, and therapeutic monitoring of infectious diseases, particularly viral infections. My 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, and 3) investigation of the performance and utility of automated nucleic acid preparation instrumentation in the clinical laboratory. We utilize a variety of conventional (cell culture, antigen detection) and molecular techniques (nucleic acid amplification, primarily PCR and real time PCR).
