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.

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.
