Natural infections informing immunotherapies

Research Overview

The Juelg lab aims to link preclinical and clinical studies to identify and test the most promising immunological strategies to prevent and treat infections. The lab is specifically interested in evaluating passive and active immunization approaches using broadly neutralizing antibodies and novel vaccine candidates.


Dr. Juelg received an MD and PhD from Christian Albrecht University in Kiel, Germany. He completed a postdoctoral research fellowship with Dr. Bruce Walker before undergoing internal medicine training at MGH and a fellowship in infectious diseases through the combined program at MGH and Brigham and Women’s Hospital.
