About

I am a trial lawyer with experience spanning more than 170 trial days. I have particular expertise representing clients in the life sciences industry in complex product liability and mass tort litigation. As a member of eight trial teams, I have experience crafting opening statements and closing arguments, and examining key fact and expert witnesses at trial. I was a member of the team that tried the only opioids case involving wholesale distributors to verdict, resulting in a complete defense win. I also participated in trial wins involving Pradaxa and Roundup. I am skilled in all stages of litigation, including taking and defending depositions, preparing witnesses, and drafting Daubert and dispositive motions. I have argued numerous motions in state and federal court, including recently in the first multi-plaintiff trial in St. Louis involving allegations that Roundup causes non-Hodgkin’s lymphoma. I also represent clients on appeal and have authored amicus briefs before the United States Supreme Court. Super Lawyers has recognized me as a Products Liability “Rising Star.” I joined Covington following a clerkship with the Honorable Paul V. Niemeyer on the United States Court of Appeals for the Fourth Circuit. Prior to my clerkship, I graduated magna cum laude from Harvard Law School, where I served as an Executive Editor of the Harvard Law Review.
