ABBL Welcomes Our Newest Scientists

Dr. Charles Li

Research Veterinary Medical Officer


Investigate the pathogenesis of Clostridium perfringens in inducing necrotic enteritis (NE) in chickens, and develop an effective challenge model and vaccines specific for NE; Develop immune reagents to support immunology research for avian communities; Study the effects of antibiotics alternatives products on the gut microbiota in metagenomics and metatranscriptomics approaches. The ultimate research goal is to promote poultry health and enhance food safety:

Dr. Monika Proszkowiec-Weglarz

Research Molecular Biologist (poultry)


Assess, develop and apply microbiome- and metagenomic-based strategies in poultry to define the role of the microflora in the regulation of nutrient uptake and utilization in the gastrointestinal tract during post-hatch development in broilers.

Dr. Katie Summers

Research Microbiologist (swine) 

Develop alternative strategies to replace or reduce the use of conventional antibiotics for improved growth, swine health, and product safety. Identify biomarkers of gut health and efficient nutrient utilization that are associated with specific changes in the microbiome of the weanling pig gut. Use of molecular tools to understand the role of genes relevant to health, growth, or intestinal function in swine with the goal of identifying targets for alternatives to antibiotic growth promotants.
