Dr. Brian Ladman is a Senior Scientist in the Department of Animal and Food Sciences at the University of Delaware. He helps lead the University of Delaware Poultry Health System (UDPHS) which provides diagnostic testing and technical assistance to poultry integrators, growers, veterinarians and members of allied industries around the world.  This work often leads to research projects to develop or improve diagnostic tools for avian pathogens as well as develop and/or evaluate avian vaccines and vaccination programs for such pathogens like AIV, IBV, IBDV, ILTV, and NDV. Recent projects include: development and evaluation of an emergency vaccine to protect against a novel strain of IBV, evaluation of feed supplements to improve avian gut health, evaluation of international IBV and IBDV vaccines, and evaluation of avian influenza vaccines held in the National Stockpile. To support these efforts of the UDPHS, Dr. Ladman has become an expert in USDA/CDC Select Agent regulations, Biosafety level 3 laboratory management and ISO17025 accreditation.
