Main research interest of K. Zub is the ecology, physiology and genetics of small mammals. He also has conducted studies (based on pellet analyses) on diet composition in many raptor and owl species breeding in Poland. His current research focus on: (1) energy expenditures in small mammals (using doubly labeled water technique and measurements of resting metabolic rates); (2) effect of body mass and metabolic rates variation on winter survival of small mammals (weasels, voles); (3) quantitative genetics (heritability of body mass and metabolic rates in weasels and voles), (4) genetic structure of small mammals populations, and (5) population dynamics of weasels and voles.
