William recently obtained the IST+ post-doctoral fellowship and will join the group in January 2018. He received his PhD degree from the Université Paris Diderot in France, under the supervision of Ivan Favero. His thesis mainly involved micro-fabrication of Gallium Arsenide disk resonators and cryogenic optomechanical experiments. He obtained his master of science from the university of Arizona’s College of Optical sciences. Email:


Martin Zemlicka
Superconducting Circuits

Martin studied physics at the Comenius University in Bratislava, Slovakia. During his master’s degree, he won the first place in Czech-Slovak Student Scientific International Conference in the field of applied physics, and defended his diploma thesis titled ‘Measurement and numerical analysis of superconducting coplanar resonators’. Following graduation, he started his PhD study as a part of Prof. Grajcar’s group and as a co-investigator of the European IQIT (Integrated Quantum Information Technology) project. He earned his PhD in 2016 with the dissertation thesis ‘Physical phenomena in disordered superconductors’ in which he analyzed prospective materials for superconducting nanotechnology applications. He received a postdoctoral fellowship from the Slovak academic information agency (SAIA) to work at IST Austria in the summer of 2017. Email:

Shabir joined the group as a Postdoctoral Fellow in February 2016. In 2012, he received a PhD degree from the University of Isfahan, under supervision of Prof. M. Soltanolkotabi and Prof. M. H. Naderi. He received the best PhD thesis award for his thesis titled “Nonlinear phenomena in optomechanical cavities“ and spent 6 months as a visiting researcher at the University of Camerino under supervision of Prof. D. Vitali and Prof. P. Tombesi.  After his PhD, he worked as a postdoctoral fellow in the group of Prof. D. DiVincenzo at RWTH Aachen University. Shabir recently won the Marie Skłodowska-Curie fellowship to work towards Quantum Teleportation and Quantum Illumination in Cavity Optomechanics. Email:

Matthias WulfPhoto_Matthias

Matthias finished his Master study in electrical engineering at the University of Kassel. He received the VDI award for the best thesis in a technical or natural science subject written at the University of Kassel in the year 2008 for his bachelor. He obtained his PhD in nanophotonics at the FOM Institute AMOLF under the supervision of Prof. Kobus Kuipers. His research focused on the investigation of the nonlinear effects occurring during the propagation of ultrashort pulses in nanoscale waveguides like photonic crystal waveguides. Matthias joined the lab as a Postdoctoral Fellow in January 2016. Email:

PhD Students

Farid Hassani Bijarboonehimg_20170316_153553.jpg
Superconducting Circuits

Farid graduated with a master of electrical engineering from K. N. Toosi University of Technology in Tehran under the supervision of Dr. Farshid Raissi. In his master thesis he investigated the exponential behavior of the I-V curve in high Tc superconductors by introducing a new mechanism for vortices and anti-vortices, which was published in Applied Physics Letters in June 2014. After graduation, he joined Dr.Raissi’s team to work on fabrication of superconducting circuits based on Nb/AlOx/Nb Josephson junctions technology. Farid joined IST as a PhD student in September 2017.

Georg Arnoldbewerbungsfotoga

Georg accomplished his MSc in Engineering Physics at the Graz University of Technology in the group of H. Plank. There he used additive particle beam based fabrication techniques for the development of a nano-mechanical gas sensor. His research was awarded with the Advancement Award of the Graz University of Technology and the Research Scholarship sponsored by the Chamber of Commerce. Georg visited the group for four months from Nov 2016. Now a PhD student of the IST graduate school and recently won a DOC fellowship. Email:

Elena RedchenkoV2k-of3uWFk
