My research focuses on developing novel soft materials and device architectures for biomedical sensors and drug delivery. I am currently a postdoctoral fellow in Prof. Daniel Anderson and Prof. Robert Langer’s group at MIT/Boston Children’s Hospital. I received my PhD in Materials Science and Engineering from the University of Illinois at Urbana-Champaign, under Prof. John Rogers, and was a visiting fellow at Northwestern University, at the Center for Bio-Integrated Electronics, from 2016-2019. I am also a co-founder of Rhaeos, a company spun out from my PhD research in wearable sensors for patients with hydrocephalus. I received my BS and MS in Mechanical Engineering from Washington University in St. Louis.
