She lives in the Shaw neighborhood with her husband, daughter, two dogs, and a giant African sulcata tortoise. She enjoys spending time outdoors, exploring her vibrant neighborhood, and walking through Tower Grove Park.

Outside of her professional life, Erin stays busy coaching soccer and leading a Girl Scout troop. She has a passion for traveling with friends and family, discovering new restaurants, and staying active at the gym. For her, working at WashU has been a cornerstone of her career, and she couldn’t imagine being anywhere else.
