Department

Animal and Poultry Science

Research Interests

1. Patho-physiological and biochemical mechanisms leading to heart failure in fast growing broiler chickens, with emphasis on dietary risk factors associated with predisposition of rapidly growing broilers to heart failure.

2. Molecular mechanisms associated with weaknesses of first line of defence mechanisms against pathogens involved in cellulitis in meat type poultry.

3. Pathogenesis of necrotic enteritis, with emphasis on host-pathogen interaction, pathogen mediated cellular and tissue signaling.

Education

DVM. (Poland), B.Sc., M.Sc., Ph.D. (Sask.)
