Research Interests

Discovery and characterization of diagnostic and therapeutic monoclonal antibodies

Research Summary

My laboratory studies human immune repertoires in health and disease using phage display technologies for the production of human and non-human monoclonal antibodies relevant to transfusion medicine, benign hematology, infectious diseases, and oncology. Current studies focus on developing targeted drug delivery methods using red cell antibodies coupled to novel anti-thrombotic/anti-inflammatory molecules; cloning monoclonal primate neutralizing Dengue, Ebola, MERS and Zika virus antibodies for human in vivo antibody gene expression therapy; and isolating recombinant human and humanized antibody fragments for the design of T-cell chimeric antigen receptors for cancer therapy.
