Stephanie Wehner is a professor at QuTech, Delft University of Technology. Her research advances quantum information theory and its applications to both computer science and physics. From 2010 to 2014, her research group was located at the Centre for Quantum Technologies, National University of Singapore, where she was first an Assistant and later Associate Professor.

Before coming to Singapore, Stephanie was a postdoctoral scholar at the California Institute of Technology in the group of John Preskill. In Singapore, she was awarded the position of Dean's Chair. In Europe, she was awarded an ERC Starting Grant. In a former life, she worked as a professional hacker in industry.

Stephanie is one of the founders of QCRYPT, which has become the largest conference in quantum cryptography.
