• Title:
    Assistant Professor, Biology
  • Department:

William Schmidt



Dr. William Schmidt has been part of the Biology faculty since August 2020. He earned his Ph.D. from Boston University School of Medicine in 2014 and performed his postdoctoral research at Johns Hopkins School of Medicine in the Cardiology Division. Dr. Schmidt’s research has focused on elucidating the underlying molecular mechanisms responsible for modulating skeletal and cardiac muscle contraction with a focus in understanding the mechanistic bases for pathological and disease development. Since coming to Rivier, Dr. Schmidt has pursued a passion for teaching undergraduates and has experience teaching introductory biology, human anatomy and physiology, genetics, and cell and molecular biology. He continues to pursue his research interests at Rivier University and encourages any student who might be interested in investigating molecular mechanisms related to disease to contact him directly.
