Much of Christian's experience also includes taking the lead with factual and evidentiary development of cases, drafting and responding to discovery requests, preparing corporate designee witnesses for deposition, and taking and defending fact witness depositions of plaintiff-related parties and treating physicians. He works with expert witnesses in various areas, including epidemiology, neurology, psychiatry, U.S. Food and Drug Administration (FDA) regulations, and pharmaceutical product labeling. Christian also has experience in courtroom client advocacy — obtaining favorable rulings after successfully arguing expert-related motions, motions in limine, a motion for summary judgement, and a protective order in Maryland state court.
