Scott Weber

Associate Professor
Microbiology & Molecular Biology

3137 LSB
Provo, UT 84602


I am an Associate Professor in the Department of Microbiology and Molecular Biology at BYU. My research is centered on improving the immune system response to infectious disease, asthma, and cancer. I teach Advanced Molecular Biology, Immunology and Flow Cytometry courses.

Previously I was an Instructor and Postdoctoral Fellow at Washington University School of Medicine in St. Louis. I earned my Ph.D. from the University of Illinois and my undergraduate and masters degrees are from Brigham Young University.

Teaching Interests

Immunology, Molecular Biology, and Flow Cytometry

Research Interests
T cells play a critical role in protection from infectious disease, cancer, Alzheimer's disease, and asthma. Helper T cells coordinate the adaptive and innate immune responses and deliver essential survival signals for the generation of cytotoxic memory T cells, antibody responses, and protective immunity. A better understanding of T cell activation and memory formation may enable improvement of infectious disease vaccines, help with the discovery of cancer treatments, and decrease Alzheimer's disease and asthma development.

The main areas of research in the Weber Lab are: 1) Understanding the molecular basis of T cell activation and improving the T cell memory response to infectious disease 2) Engineering improved immunological proteins to combat cancer 3) Determining the involvement of the immune system in Alzheimer's disease and 4) Understanding how environmental exposures influences asthma development.
