Saahir Khan

Saahir Khan serves as a Clinical Assistant Professor of Medicine (Clinician Educator) at the University of Southern California, where he focuses on immunological responses to SARS-CoV-2. His research bridges clinical medicine and laboratory science, with significant contributions to understanding antibody dynamics during the COVID-19 pandemic through rigorous serological analysis and innovative diagnostic development.

Dr. Khan's primary research domains include Immunology, Virology, Infectious Diseases, Serology, Public Health, and Vaccinology. His work has advanced knowledge in antibody characterization in pathogen-reduced plasma, seroprevalence risk factors among healthcare workers, and comparative immune responses between natural infection and mRNA vaccination. He pioneered the application of coronavirus antigen microarrays for high-specificity antibody profiling, enabling detailed analysis of cross-reactivity and temporal antibody persistence.

Analysis of his 15 most recent publications (2020-2023) reveals consistent methodological innovation in serological techniques applied to critical pandemic questions. His studies frequently compare infection versus vaccination-induced immunity, evaluate pathogen reduction efficacy in convalescent plasma, and assess real-world infection control measures. The research demonstrates strong translational impact, directly informing clinical protocols for plasma therapy and occupational safety in healthcare settings through data-driven risk assessment.
