Petro Kostrobiy was born on December 19, 1949, in the village of Bohorodchany, Bohorodchany District, Ivano-Frankivsk region. In 1966, he graduated with a gold medal from Secondary School No. 2 in Ivano-Frankivsk. That same year, he entered the Faculty of Physics at Ivan Franko Lviv State University, graduating in 1971. From December 1971 to November 1974, he studied in the graduate school at the Lviv Branch of the Institute of Theoretical Physics (ITF) of the Academy of Sciences of the Ukrainian SSR. His scientific supervisor was the outstanding scientist in the field of statistical physics of condensed systems, now the academician of the National Academy of Sciences of Ukraine, Ihor Rafailovych Yukhnovskyi. In November 1975, he defended his candidate dissertation in the specialty 'Theoretical and Mathematical Physics' at the ITF of the Ukrainian SSR Academy of Sciences, becoming a Candidate of Physical and Mathematical Sciences in March 1976. From September 1979, after winning a competition, Petro Kostrobiy began his scientific and pedagogical activity at the Department of Higher Mathematics of Lviv Polytechnic Institute as a senior lecturer, associate professor (since 1983), and professor (since 1999). While working at Lviv Polytechnic, he completed and defended his doctoral dissertation in 2009. After defending his doctoral dissertation, he continued his active scientific work on the development of a statistical theory of reaction-diffusion processes in ‘metal–gas’ systems. New approaches proposed by P.P. Kostrobiy together with M.V. Tokarchuk have been effectively used in solving a number of problems in the quantum-statistical theory of thin-film metallic systems (together with B.M. Markovych), the study of proposed mathematical models of catalytic-diffusion processes on metallic catalysts (together with V.I. Alekseyev and I.A. Ryzhyi), and electro-diffusion processes in solid-state batteries (together with O.V. Viznovych, M.V. Tokarchuk, B.M. Markovych). The results of this work have been published in more than 200 scientific papers and four scientific monographs. The development of this topic led to increased cooperation with academic institutions of the National Academy of Sciences of Ukraine (Institute of Theoretical Physics named after M. Bogolyubov, Institute of Condensed Matter Physics, Institute of Applied Problems of Mechanics and Mathematics named after Y. Pidstryhach, Center for Mathematical Modeling of the IPPMM NAS of Ukraine). As a result of this cooperation, branches of the department were created at the IPPMM and IFCS. This allowed leading scientists from these institutions to be involved in teaching and supervising master’s students and PhD candidates. His active scientific activity has been recognized with an honorary certificate from the Cabinet of Ministers (2017) and an award from the Ministry of Education and Science of Ukraine 'For Scientific Achievements' (2019). Petro Kostrobiy is a member of the Expert Council on Mathematical and Natural Sciences of the Ministry of Education and Science of Ukraine, a member of two specialized Academic Councils for defending doctoral dissertations (in the DO35.052.06 council – the leading expert in the specialty 01.05.02 – 'Mathematical Modeling and Computational Methods'). He is also the deputy editor-in-chief of the English-language scientific journal 'Mathematical Modeling and Computing'. Under his guidance, 1 doctoral and 7 candidate dissertations have been defended. From June 1991 to September 2005, P.P. Kostrobiy worked as Vice-Rector for Educational Work (1991–1993) and First Vice-Rector (1993–2005) of Lviv Polytechnic. During his time in these positions, he actively participated in the work of reforming the higher education system of Ukraine. Under his direct leadership, the multi-level system (bachelor–specialist, master’s) of training specialists was first implemented in Ukraine at Lviv Polytechnic. He developed and implemented the concept of training military specialists in civilian higher education institutions; created the department of military training (now the Academy of Land Forces of the Ukrainian Armed Forces); and developed and implemented the concept of educational-scientific institutes. As a member of the author teams, he participated in the development of the first Ukrainian Law 'On Higher Education,' as well as ministerial regulations on 'Higher Educational Institutions,' 'Multi-level System of Specialist Training,' 'Organization of the Educational Process,' and others. For his significant contribution to the work of reforming higher education in Ukraine, P. Kostrobiy was awarded the title 'Honored Worker of Education' in 2003, the Ministry of Education and Science of Ukraine Badge 'Petro Mohyla' (2005), and numerous honorary certificates from the Ministry of Education and Science of Ukraine.
