Research Interests

My research concerns innate immunity and the pathogenesis of Salmonella infections. We have been studying the immune response to Salmonella and the fungus Coccidioides immitis. We have use Salmonella and mouse mutants to help elucidate the complicated interplay between host and pathogen. We also use mutant mice to study coccidioidomycosis, emphasizing the role of pattern-recognition receptors in innate immunity.

Dr. Fierer graduated from NYU School of Medicine and then did a residency in Internal Medicine at Yale-New Haven Hospital, sandwiched around a two year stint in the Epidemic Intelligence Service at CDC. He did his Infectious Diseases Fellowship training with Abraham Braude at the University of Pittsburgh and then at UCSD. He joined the faculty at UCSD School of Medicine as an Assistant Professor in 1971 and has remained at that institution ever since.
