Elle is a bit of a rolling stone as DC is the 10th State (or district) where she has lived. However, she has found a great sense of home amongst family, friends and on the saddle of one of her bicycles. Elle is passionate about all things endurance sport, particularly triathlons and open water swimming. She particularly enjoys eating: the fourth event of triathlon, and has never met a Bahn Mi she didn’t like. She hopes to combine her love of research, public health and disaster medicine. She looks forward to a career with the USPHS, and considers it an honor to serve.
