Igor Buzalewicz graduated in Biomedical Engineering in 2007 and Optometry in 2009 from Wroclaw University of Science and Technology. In 2013, he obtained a Ph.D. degree with honors in Technical Sciences in the field of Biomedical Engineering from the Institute of the Biocybernetics and Biomedical Engineering of the Polish Academy of Science. Currently, he is an Assistance Professor at the Department of Biomedical Engineering at the Faculty of the Fundamental Problems of Technology of the Wroclaw University of Science and Technology in Poland. He has been working on the application of the optical phenomena in medical and microbiological diagnostics, on the biological matter–light interaction-based therapeutic procedures and on the development of novel optical systems for diagnostics purposes. He is an author and co-author of several national and international patents concerning the configuration of novel optical systems for microbiological diagnostics and phototherapy. His main interests are digital diagnostics based on optical phenomena, applications of spectral imaging, digital holographic tomography, and interferometry for characterization of single-cells (prokaryotic, eukaryotic), and cytopathic effects, bacterial biofilms, and photodynamic therapy.
