PhD Student
Full Field Fourier Domain OCT, Translational Research, Computational optics, Physical Optics,
Description
An inexhaustible generator of ideas, which he turns with determination into reality. Piotr is currently a PhD student at the International Center for Translational Eye Research Center (ICTER) and the University of Warsaw. He is developing a new implementation of optical coherence tomography (OCT) using ultras fast cameras and various light modulation scenario. He graduated from the Universitat Politècnica de Catalunya in Barcelona, where he prepared his Master’s thesis on medical optics in Turgut Durduran’s group at ICFO. In 2017 he graduated from the University of Warsaw with a bachelor degree in physics.
During his studies, Piotr was involved in grants funded by the FNP, NCN and Horyzont2020 framework. Based on his scientific achievements, he received scholarships from the Rector of the University of Warsaw, the Minister of Science and Higher Education and the La Pedrera Foundation within the “ICFO Summer Fellowship”. He gained experience and knowledge about optics and photonics by participating in the most important international conferences and summer schools.
