Hristina Mitrović is a research assistant in the Group for probiotic and microbiota-host interactions at the Institute of molecular genetics and genetic engineering, University of Belgrade. Her research focuses on the gut-brain axis and the role of probiotics and postbiotics in the regulation of intestinal and neuroinflammation, as well as depression.

The main focus of her work is isolation and characterization of anaerobic GABA-producing bacteria and the investigation of their effects through in vitro and in vivo models. By integrating approaches from microbiology, immunology, and neurobiology with genomic, transcriptomic, metagenomic, and metabolomic analyses, she aims to better understand the mechanisms through which microorganisms influence the intestinal, nervous, and immune systems.

Alongside her scientific research, she is actively involved in science communication and popularization through educational programs, lectures, and interactive exhibitions dedicated to the microbiome and its importance for human health.
