In 1963 he entered secondary school and graduated in 1973 with a gold medal. Last years he was educated in a special mathematical class. In parallel, he graduated the music school at Dnepropetrovsk Music College in piano classes.
In 1973 he entered the Dnepropetrovsk State University (DSU) in Mechanics and Mathematics Faculty. After 5 years of studying he graduated with honors degree on a specialty "Dynamics and Strength of Machines". Starting from 3 year he engaged in scientific work under the guidance of academician of Ukrainian National Academy of Sciences, professor V.I. Mossakovski, who at this time headed the department of "Applied Theory of Elasticity" and was the rector of the university.

In autumn of 1978 A. Sładkowski became a postgraduate student in DSU at the department of "Applied Theory of Elasticity." Scientific leader at the preparation dissertation work was prof. V.I. Mossakovski. After finishing graduate courses in 1981, he continued the work in the Problem Scientific Research Laboratory of Strength and Reliability of Constructions DSU as a junior researcher. Based on work related to the study of contact interaction of elastic bodies and prepared research project "Study of microslip in contact of elastic bodies," which in 1983 won first prize of the All-Union Council of Scientific and Technical Societies (VSNTO).
From 1983 till 1986 he worked in the Diagnostic Branch Laboratory of Holography DSU as head of research sector. The main focus of research was the interpretation of holographic interferograms. At the same time he carried out functions of responsible executor of research.
From 1986 till 1987 he worked as a senior researcher in Research Laboratory of Economics of the Environment (NIL EKOOS) of DSU. Research during this period included the issues of statistical processing of economic information.
During 1986-1988 he also worked as an assistant in the department of "Mathematical Study of Software" DSU. He conducted lectures and workshops on programming and methods of computation.
In 1987 A. Sładkowski defended his dissertation "Microslip at a stationary interaction of elastic bodies" receiving a PhD degree in physics and mathematics in specialty 01.02.04 "Mechanics of deformable solids". Scientific supervisor of work was prof. V.I. Mossakovski. Defense of work was held on the specialized council of DSU.
Research and teaching activities of A. Sładkowski was awarded prizes and official gratitude of the Rector of DSU in 1983 (twice) and in 1987.

Until 1993 he worked as a senior researcher of the department of "Applied Mechanics". He headed the group and was responsible performer of number of research works on topics of the railway, as well as topics related to industrial vehicles. In parallel, he conducted lectures and workshops with students in a number of specialties as an assistant.
In 1989 the Higher Attestation Commission of the USSR awarded for A. Sładkowski the academic title of senior researcher in the specialty "Mechanics of deformable solids".
In 1993-1996 he trained on the habilitate courses in the department of "Applied Mechanics" DMetI, parallel he executed functions of associate professor of this department. Beginning from 1996 the position of associate professor for A. Sładkowski became the main professor, despite the fact that he carried out simultaneous research work as a senior researcher.
In 1997 A. Sładkowski defended his dissertation "Theoretical substantiation and development of rational designs of wheel-rail pairs for rail transport machines and units of mining branches." Defense of the thesis for the habilitate degree on technical sciences in specialty 05.15.16 "Mining machinery" was held on the specialized council of the National Mining Academy of Ukraine.
Since 1999 A. Sładkowski worked as a professor of the department of "Applied Mechanics" DMetI, at first in the staff of department, and since 2000 under the contract. This allowed him to combine teaching and research work in Ukraine and Poland until 2003.
In 2001 the decision of the Certifying Collegium of the Ministry of Education and Science of Ukraine awarded for A. Sładkowski the academic title of associate professor of applied mechanics, and in 2002 the same government body of Ukraine awarded the academic title of professor of the department of applied mechanics.
