Scientific biography

In 2015 Myron Rudysh graduated from the Faculty of Physics of Ivan Franko National University of Lviv with honors. Has received the full higher education in the specialty “Physics of Condensed Matter” and got a Master’s degree in Physics of Condensed Matter (Bachelor’s degree in Physics, qualification – Bachelor of Applied Physics, Teacher of Physics, Applied Physics (2013)).

From November 2015 t0 April 2016 he was a postgraduate student of the Department of Solid State Physics. From May 2016 to October 2018 he was a postgraduate student of the Department of General Physics. He graduated from the Ph.D program in October 2018.

From November 2017 to October 2018 Myron Rudysh received the academic scholarship of the President of Ukraine for university students and postgraduate students.

From November 2018 to February 2019 Myron Rudysh worked as an Engineer of the General Physics Practical Work Laboratory of the Department of General Physics of the Faculty of Physics. From February 2019 he was transferred to the position of Lead Engineer of the same laboratory and worked until August 2020.

In September 2020 he worked as an Assistant at the Department of General Physics, and from October 2020 he was enrolled as Researcher (0.25 rate) on State budget theme Fz-08F “Transformation of the optic-electronic parameters and structure of new crystalline materials for sensor devices and optoelectronics” (2020-2022 years).

The thesis is “Electronic and optical properties of lithium ammonium sulfate crystals under uniaxial stress”. Professor V. Yo. Stadnyk was a supervisor of his thesis. In 24 October 2018 Myron Rudysh defended his Ph.D. thesis. In 18 December 2018 he has been granted the degree of Candidate of Physical and Mathematical Sciences by spesiality Physics of Semiconductors and Dielectrics.

In November 2019 Myron Rudysh received the Award of the Regional State Administration and the Regional Council for Employees of Scientific Institutions and Higher Educational Institutions (Universities, Academies, Institutes) of the Lviv Region.

He was the executive of the state budget theme. By now Myron Rudysh published 98 scientific works and received 3 pathent of Ukraine for useful model.
