Biography:
Dr. Miroslaw Jonasz was born in 1949 in Poland. He completed his M.Sc. in physics in 1972 at the University of Gdansk and obtained his Ph.D. degree in physics in 1980 at the Institute of Geophysics of the Polish Academy of Sciences. Before founding his firm in 1991, he held research positions at the Polish Academy of Sciences, Stockholm University (Sweden), and Dalhousie University (Canada). He also held senior R&D engineering positions at Technicon Instruments Corporation (USA), a major manufacturer of optics-based clinical instrumentation.
