The hallmark of my research career is the development of novel antibodies and applying them toward the development of new immuno-biotechnological tools. My lab has developed an antibody discovery platform in chickens that goes from in silico sequence to epitope-specific chicken IgG (IgY) in less than 3 weeks based on in vivo CD40-targeted immunogen delivery.

Research projects include the study of the immune response in the chicken, especially the function of CD40-positive antigen presenting cells (such as the dendritic cells) in activating the humoral immune response and the development of chicken egg yolk antibodies, monoclonal antibodies and recombinant antibodies for diagnostic, prophylactic and therapeutic purposes. a Dr. Berghman was the recipient of the 2016 Zoetis Fundamental Science Award.
