Research Interests:

Dr. Wahid studies T and B cell mediated host-immune responses and induction immune memory by immunization with licensed or candidate vaccines in humans. He primarily utilizes the clinical samples obtained from volunteers participating in various vaccine trials. His ultimate goal is to enhance the endeavors of developing efficient vaccines, especially against enteric pathogens by understanding the immune correlate of protection against those diseases in humans.
