  • Senior Associate Scientist at Biogen
    Apr 2015 - Dec 2015 · 9 mos

    Tissue injury and fibrosis were the primary focus of my work at Biogen. Our group was in process of developing lung fibrosis rodent models and discovering key endpoints that are relative to disease. As a unit we were developing: • Lung fibrosis models, primarily optimizing bleomycin lung induced fibrosis • My role was characterizing key markers critical to the development of idiopathic lung fibrosis • Assisted in developing LMW therapies that suppress lung fibrosis
