Current Research Interests
Dr. Cousins’ research has evolved from understanding the nutritional significance of zinc to elucidating how this micronutrient acts as a signaling molecule through regulated cellular transporters to produce influences on cellular function, host defense mechanisms and specific diseases. The laboratory members work as a team but on individual projects built around the central theme of zinc metabolism and function using the latest available technologies. The laboratory is unique in that this experimental theme is maintained from experiments at the molecular level, to those with isolated cells, with mutant mouse models, and to those with human subjects.
