Dr Joanna M Zajac is a scientist working on quantum networks and sensing specializing in condensed matter physics and Quantum Information Science and Technology (QIST). Joanna joined Brookhaven National Laboratory in 2022 as a Quantum (Staff) Scientist. In 2023, she was awarded Department of Energy Early Career Award for her research on hybrid quantum repeaters and their applications for Quantum Networks. Before joining BNL, Joanna contributed to the development of quantum memories based on defect centers in diamond during her work at Oxford University, UK. Previously, Joanna spent 3 years working in industry. She obtained her PhD from Cardiff University working on polariton quantum fluids and their applications to optoelectronics and fundamental science. During her PostDoc appointment at Heriot-Watt University, Edinburgh, UK, she worked on quantum dot single photon emitters and their applications to Quantum Technologies.
