In 1961 he began postgraduate study and became a lecturer at the Department of Machines and Instruments for Chemical Production at Kharkiv Polytechnic Institute.
In 1966 Leonid Leonidovych defended his thesis «Research of the heat exchange process during condensing of steam and steam admixture in the channels of plate-type condensers for chemical production».
In 1969 — Associate Professor of the Department of Mechanical Equipment for Chemical Production.
In 1970 — appointed to the post of Vice-rector for academic work of Kharkiv Polytechnic Institute.
From 1977 up to present — Head of the Department of General Chemical Technology of Processes and Instruments of NTU «KhPI» (since 2005 — the Department of Integrated Technologies, Processes and Instruments).
In 1989 — defended his doctoral thesis «Principles of intensification of heat exchange, development and optimization of plate heat exchangers for chemical production».
In 1989 — Professor of the Department of General Chemical Technology of Processes and Instruments.
In 1990 — appointed to the post of the first Vice-rector for academic work at KhPI.
In 1995 — Director of the Center for Energy Saving Integrated Technologies of Kharkiv State Polytechnic University, created with the support of the British Council.
From 1999 to 2015 — Rector of Kharkiv State Polytechnic University (since 2000 — National Technical University «Kharkiv Polytechnic Institute»)
In 2015 — elected Honorary Rector of NTU «KhPI» and Adviser to the acting Rector.
Professor L. L. Tovazhnyanskyy is a well-known specialist in the field of chemical technology, who has been conducting successful research into heterogeneous-catalytic processes, chemical reactors and ecology for many years. He has developed the theoretical foundations of kinetics, heat and mass exchange in chemical catalytic processes and also worked out the theoretical basis of modeling, calculations and designing chemical reactors and plate heat exchangers for hydrogen production, ammonia synthesis, methanol, concentrated and nonconcentrated soda ash and mineral fertilizers.
Professor L. L. Tovazhnyanskyy heads a scientific school on the theoretical foundations of chemical technology, which deals with optimal integration of chemical and technological systems to increase their energy efficiency and ecological safety in chemical, petrochemical, food and other industries.
The results of L. L. Tovazhnyanskyy's scientific research are the basis for the development of numerous physical and chemical fundamentals of technologies, including technologies for industrial waste disposal and environmental protection.
Under his leadership the fundamentals of new chemical technologies and modern designs of chemical reactors, high-efficiency heat exchange apparatus have been created. They have become the basis for the creation of large-scale industrial production of bound nitrogen technology.
Scientific developments have been implemented at enterprises in Ukraine, Russia, Belarus, Uzbekistan, Kazakhstan, etc.
L. L. Tovazhnyanskyy is the author of 609 scientific publications (73 for the last 4 years), among which 20 monographs and 25 inventions. Under his guidance 8 Doctors of Science and 20 Candidates of Sciences were prepared.
