Professor of Natural sciences, working as a professor at the Department of Animal Anatomy and Physiology, Faculty of Biology and Biotechnology (WBiB), University of Warmia and Mazury in Olsztyn (UWM). Research in the field of hormonal regulation of mammalian reproductive processes. Reproductive endocrinology, especially the role of adipokines (molecules such as leptin, adiponectin, chemerin, visfatin, produced and secreted by the white adipose tissue cells, adipocytes) and orexins (hormones responsible for the regulation of, among others, appetite) in the regulation of the reproductive system. The expression and role of adipokines and orexins in the control of the hypothalamic-pituitary-ovarian axis and in the regulation of processes occurring in the uterus of domestic pigs during early pregnancy (period critical for embryo survival) and during the oestrous cycle. The expression and role of orexins and their receptors in the structures of the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes of the European beaver depending on sex and the season of the reproductive activity. Determination of the transcriptomic changes (global gene expression, alternative splicing, long non-coding RNAs and single nucleotide polymorphism) in the adrenal cortex and the endometrium cells of domestic pig under the influence of lipopolysaccharide (LPS) Salmonella Enteritidis.
