Prof. Ragulya received his Ph.D. (1993) and D.Sc. (2001)
from the Frantsevich Institute for Problems of Materials Science, NAS of Ukraine, where he has been based since 1985, working at the forefront of nanomaterials and sintering technology.

In the early 1990s, he developed the theoretical foundations of Rate Controlled Sintering (RCS) – building on the experimental groundwork laid by Prof. H. Palmour – and proposed a broader framework of rate-controlled thermally activated processes, subsequently validated across a range of technological applications including the synthesis of nanosized ceramic and metallic particles. This body of work was recognised with the State Prize of Ukraine in 2015.

Since 2002, he has served as Deputy Director of the Frantsevich Institute, leading research into nanosized particles, nanostructured ceramics, and ceramic composites. In 2023, he co-founded IRC NANO. He is the author of 6 books, 1 textbook, more than 270 papers, and 16 patents in the field of nanomaterials.
