Janik is now heading the group on Physical Foundations of IT Security at the German Aerospace Center (DLR) Institute of Optical Sensors in Berlin / TU Berlin. The information below may no longer be current.



I studied physics at the Technische Universität (TU) Berlin, and Universidad Complutense de Madrid, graduating in Febuary 2009. I did my PhD on Integrated Quantum Hybrid Systems in the Benson Group at Humboldt Universität zu Berlin. I worked in the Grangier group in Institut d'Optique in Paris and the Reitzenstein Group at TU Berlin. My prize-winning research comprises nano photonics, quantum dots, NV centers and atomic physics. Beginning of 2016 I joined the Treutlein Group in Basel as a Marie Curie Fellow working in the project 3-5-First! on the realization of a cold atom-semiconductor quantum interface.
