Dimitar’s research interests are in the fields of Microbial Ecology, Bioinformatics and Biogeochemistry. Special interests include:

• The role of iron and sulfur cycling to soil organic carbon storage and carbon capture through enhanced rock weathering.
• Use of bacteria and their products for biotechnological acceleration of carbon capture.
• The genomics and transcriptomic mining of basalt-colonising bacteria in soil including heterotrophic and lithoautotrophic groups.

Some of his contributions include:

• Development of novel techniques for measuring weathering in soils through Magnetic separation and sequential Phosphoric acid digest and ICP-OES (MagPI).

• Development of synthetic chelator formulations for modulating the soil native microbiome towards accelerated rock weathering.

• Unearthing a distinct and functionally important community of microorganisms specifically colonising basalt grains weathered in soil generating energy and organics through oxidation of basalt-derived sulfur and hydrogen.

• The discovery that N₂-fixing legume trees interact with their microbiomes to drive greater weathering rates and targeted nutrient extraction (P, K, Mo) in both Neotropical and Australasian forest systems helping forest recovery and re-growth.
