Ivan lgnjatovic has more than 14 years of experience of scientific and research activities in the field of concrete material and reinforced concrete structures. He obtained his Ph.D. with the thesis: Ultimate limit strength of reinforced recycled aggregate concrete beams. During his phd research he carried out a lot of experimental work on the properties of the recycled aggregate concrete and flexural and shear behavior of the structural elements - beams made with such a concrete. Dr. lgnjatovic is the author or co-author of several reviewed papers published in journals, scientific and professional periodicals, international and domestic congresses and symposia. These papers present results of investigation of possibilities for utilization of recycled aggregate concrete in structural elements, as well as durability and service life design of reinforced concrete structures. His research includes also utilization of supplementary cementitious materials (fly ash, slag) in structural concrete covered by investigation of high volume fly ash concrete and alkali activated fly ash concrete. A part of his research field is dedicated to the seismic analysis of reinforced concrete and masonry structures.

As a researcher and professor of concrete structures, Dr lgnjatovic is fully interested in research related to the durability of structural elements which are exposed to combination of loads/stresses and deterioration processes. Dr lgnjatovic is a mentor of PhD thesis with the subject ,,Influence of cracks on the deterioration mechanisms and durability of reinforced concrete structures': which is complementary to the research planned to be conducted under the WG4 activities.
