Stephanie Danyluk, M.S.
Stephanie is a Clinical Research Coordinator for the DeFrate Lab. Her role in the lab is mostly regulatory, as she manages all clinical studies involving patients. She makes sure that each study is conducted efficiently, safely, and within the guidelines of ICH’s “good clinical practice.” Within her role, she deals directly with research participants, investigators, and the Institutional Review Board.
