Research Interests

Research in Dr. Abasht’s lab has focused on studying Wooden Breast, a novel muscle disorder of unknown etiology in commercial broiler chickens. The most severe cases of the disease are characterized by extreme stiffness of the breast muscle (pectoralis major), which can be detected by manual palpation. Using a combination of methods, including transcriptome sequencing (RNA-seq), histology, electron microscopy, and bioinformatics, Dr. Abasht’s lab investigates and hopes to identify factors causing this myopathy in modern broiler chickens. The lab group also studies genetic regulation of myogenesis and adiposity as they relate to healthy muscle growth in chickens.
